CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] Pursuant to 35 U.S.C. .sctn. 119 (a), this application
claims the benefit of an earlier filing date and right of priority
to International Application No. PCT/KR2020/005494 filed on Apr.
27, 2020, the contents of which are hereby incorporated by
reference herein in its entirety.
BACKGROUND
1. Field
[0002] This disclosure relates to a mobile terminal for displaying
content of an application and a control method thereof. One
particular implementation relates to a mobile terminal for
displaying content of an application in an area corresponding to an
input received on a display based on the input, and a control
method thereof.
2. Description of the Related Art
[0003] Advances of network technologies and expansions of
infrastructures have enabled an electronic device to perform
various and professional tasks. In this regard, there has been an
increasing desire for an electronic device with a display that
displays content on a large screen.
[0004] However, a display providing a large screen may increase in
size in proportion to a screen size. Thus, it is necessary to
consider a portability along with a size of the display in terms of
an electronic device of which the portability is emphasized, such
as a mobile terminal.
[0005] For this, there can be considered a method to change a size
of a display as necessary by applying a foldable or rollable
display having a sufficient elasticity to the electronic device.
For example, a portion of a display may be rolled up to a rear side
of a mobile terminal, and rolled out or moved as necessary such
that an exposed area of the display increases.
[0006] When the size of the display is changed, a content display
area may also be changed to correspond to the change in size. For
example, while content is displayed on a front side of the mobile
terminal, a portion of the front side may be rolled to a rear side
so a front-side exposed display size is changed. In this example, a
size of an area displaying the content may be changed based on the
change of the display size. Therefore, there is a desire for a
method to effectively provide content by reflecting a size change
of a display in consideration of a user's convenience of use.
SUMMARY
[0007] An aspect provides a mobile terminal for providing content
and a control method thereof. The mobile terminal may display
content of an application in an area corresponding to a received
input when a display of the mobile terminal is changed in size,
thereby reflecting user's needs and achieving increased efficiency
in providing content.
[0008] Technical goals of the present disclosure are not limited as
mentioned above and, although not mentioned, may include goals that
can be clearly understood by those skilled in the art to which the
present disclosure pertains, from the following description.
[0009] According to an aspect, there is provided a mobile terminal
including a display and a controller. The display is located at a
first side and a second side of the mobile terminal such that a
size by which the display is located at the first side is
changeable, the second side facing the first side. The controller
is configured to display first content of a first application in a
first area of the display located at the first side and display
second content of a second application in a second area of the
display located at the first side, arrange at least a portion of
the first area of the display on another side, and display the
first content of the first application in at least a portion of the
second area when a first input related to the first application is
received.
[0010] According to another aspect, there is also provided a method
of controlling a mobile terminal. The mobile terminal includes a
display located at a first side and a second side of the mobile
terminal such that a size by which the display is located at the
first side is changeable, the second side facing the first side.
The method includes displaying first content of a first application
in a first area of the display located at the first side and
displaying second content of a second application in a second area
of the display located at the first side, arranging at least a
portion of the first area of the display on another side, and
displaying the first content of the first application in at least a

various embodiments as described below. Also, the operation,
control, or control method of the mobile terminal may be
implemented on the mobile terminal through an execution of at least
one application program stored in the memory 170.
[0047] FIG. 2 illustrates front views of a mobile terminal in a
first state and a second state, and FIG. 3 illustrates rear views
of the mobile terminal in the first state and the second state. (a)
of FIG. 2 and (a) of FIG. 3 illustrate the first state in which the
mobile terminal is retracted. (b) of FIG. 2 and (b) of FIG. 3
illustrate the second state in which the mobile terminal is
extended.
[0048] As illustrated, the mobile terminal 100 in the first state
is retracted and has a smaller size when compared to the mobile
terminal 100 in the second state. Also, in the first state, a
display part or display 151 located at a front side of the mobile
terminal 100 may be reduced in size when compared to the second
state. The mobile terminal 100 may be extended in a first direction
D1 in the first state to enter the second state. In the second
state, as shown in (b) of FIG. 2, the size of the mobile terminal
100 and the size of the display 151 located at the front side may
increase when compared to the first state. Also, in the second
state, the size of the display 151 located at a rear side may be
reduced as shown in (b) of FIG. 3. In other words, a display's
portion located at the rear side of the mobile terminal 100 in the
first state may move to the front side of the mobile terminal 100
in the second state.
[0049] In the following description, a direction in which the
mobile terminal 100 and the display 151 thereof are extended or
enlarged may be referred to as the first direction D1. In addition,
a direction in which the mobile terminal 100 and the display 151
thereof are contracted, retracted, or reduced in the second state
to enter the first state may be referred to as a second direction
D2. Also, a direction vertical to the first direction D1 and the
second direction D2 may be referred to as a third direction. The
following description may be based on a case in which the first
direction and the second direction are horizontal directions and
the third direction is a vertical direction. In some cases, based
on a placement of the mobile terminal 100, the first direction D1
and the second direction D2 may be vertical directions and the
third direction may be a horizontal direction.
[0050] The display 151 may use the flexible display 151 to be bent
so that a position of the display 151 is changeable. The flexible
display 151 may be maintained in a flat state like a typical flat
panel display and include a display (e.g., electronic paper) to be
curved, bent, folded, twisted, or rolled like a paper. Also, the
flexible display 151 may include a lightweight and durable display
fabricated on a thin and flexible substrate. The flexible display
151 may be bendable in a predetermined direction like a paper and
disposed such that a curvature is changed in the first
direction.
[0051] The electronic paper may be a display technology based on
characteristics of a general ink, and different from the typical
flat panel display in using reflected light. The electronic paper
may use a twist ball or electrophoresis using a capsule to change
information.
[0052] In a state in which the flexible display 151 is not deformed
(for example, a state having an infinite curvature radius,
hereinafter, referred to as a default state), a display area of the
flexible display 151 may be a plane. In the default state, when the
flexible display 151 is deformed by an external force (for example,
a state having a limited curvature radius, hereinafter, a deformed
state), the display area may be a curved plane. As illustrated,
information displayed in the deformed state may be visual
information displayed on the curved plane. The visual information
may be implemented by individually controlling light emission of
sub-pixels arranged in a matrix form. The sub-pixel may be a
minimum unit for implementing one color. When the external force is
applied to the flexible display 151, the flexible display 151 may
be changed from a flat state which is the default state to a curved
state.
[0053] The flexible display 151 may implement a flexible touch
screen in combination with a touch sensor. In response to a touch
being input to the flexible touch screen, the controller 180 of
FIG. 1 may perform a control corresponding to the touch input. The
flexible touch screen may be configured to sense a touch input even
in the deformed state as well as the default state.
[0054] The touch sensor may sense a touch (or touch input) applied
to the touch screen based on at least one of various touch types
including a resistive type, a capacitive type, an infrared type, an
ultrasonic type, and a magnetic field type.
[0055] As an example, the touch sensor may be configured to convert
a change such as a pressure applied to a predetermined portion of
the touch screen or a capacitance generated at the predetermined
portion into an electrical input signal. The touch sensor may be
configured to detect a position at which a touch object applying a
touch on the touch screen is touched on the touch sensor, an area,
a touch pressure, a touch capacitance, and the like.
[0056] The mobile terminal 100 may include a deformation detection
means that detects a deformation of the flexible display 151. The
deformation detection means may be included in the sensing part 140
of FIG. 1.
[0057] The deformation detection means may be provided in the
flexible display 151 or a case (a first frame 101 and a second
frame 102 described below) to sense information related to the
deformation of the flexible display 151. The information related to
the deformation may include, for example, a direction in which the
flexible display is deformed, a degree of deformation, a deformed
position, a deformation time, and an acceleration at which the
deformed flexible display 151 is restored. In addition, the
information related to the deformation may be various information
to be detected in response to the flexible display 151 being
bent.
[0058] Also, based on the information related to the deformation of
the flexible display 151 detected by the deformation detection
means, the controller 180 may change information displayed on the
flexible display 151 or generate a control signal for controlling
functions of the mobile terminal 100.
[0059] The deformation of the flexible display 151 may vary based
on positions of the first frame 101 and the second frame 102. As
illustrated in FIG. 2, since a bent position of the flexible
display 151 is determined based on the positions of the first frame
101 and the second frame 102, a front-side exposed area and a
bending-deformed position of the flexible display 151 may be
calculated based on the positions of the first frame 101 and the
second frame 102 instead of the deformation detection means of the
flexible display 151.
[0060] A state change (to the first state or the second state) of
the flexible display 151, for example, a size change of the display
151 occurring at the front side or the rear side of the mobile
terminal 100 in response to a size change of the mobile terminal
100 may be manually performed by force applied by a user but not be
limited to such a manual manner. For example, when the mobile
terminal 100 or the flexible display 151 is in the first state, the
mobile terminal 100 or the flexible display 151 may be changed to
enter the second state by a command of the user or an application
irrespective of the external force applied from the user. To
automatically deform the flexible display 151 without applying the
external force, the mobile terminal 100 may include a driving part
200 described below.
[0061] The flexible display 151 may be rolled and bent 180.degree.
with covering a first-direction side portion of the mobile terminal
100. Based on the side portion of the mobile terminal 100, a
portion of the flexible display 151 may be located at the front
side of the mobile terminal 100 and another portion of the flexible
display 151 may be located at the rear side of the mobile terminal
100. For ease of description, the flexible display 151 located at
the front side may be referred to as a front-side portion and the
flexible display 151 located at the rear side may be referred to as
a rear-side portion. The mobile terminal may extend in the first
direction or retract in the second direction opposite to the first
direction as illustrated in FIG. 2. In this case, an area of the
flexible display 151 located at the front side may be changed. In
other words, sizes of the front-side portion and the rear-side
portion may be changed based on a state change of the mobile
terminal.
[0062] A portion of the flexible display 151 located at the front
side of the mobile terminal 100 may be unmovably fixed to a front
side of the first frame 101 while another portion located at the
rear side of the mobile terminal 100 is movably provided at the
rear side.
[0063] The flexible display 151 may be rolled or released at a
first-direction side portion of the mobile terminal 100. In this
case, a portion located at the rear side of the mobile terminal 100
may be moved to adjust a size of an area of the flexible display
151 located at the front side of the mobile terminal 100. Since the
area of the flexible display 151 is set and the flexible display
151 is configured as one continuous body, an area of the rear-side
portion may be reduced when an area of the front-side portion is
increased. The display 151 may be rolled in the second frame 102
that is movable relative to the first frame 101, for example, on a
first-direction side portion of the second frame 102. Also, in
order to adjust the area of the display 151 at the front side of
the mobile terminal 100, the display 151 may be inserted or pushed
into the second frame 102 or withdrawn or pulled out from the
second frame 102 while being rolled up at the second frame 102
based on a moving direction of the second frame 102. Such operation
will be further described below along with other related components
of the mobile terminal 100.
[0064] In general, an antenna may be provided in a case or a
housing of the mobile terminal 100. However, due to the flexible
display 151 that covers the mobile terminal 100 from the front
surface to a rear surface thereof, a part for mounting the antenna
in the case or housing may be restricted. For this reason, the
antenna may be embodied on the flexible display 151. An antenna on
display (AOD) may be in a form of a transparent film in which an
electrode layer including a pattern and a dielectric layer are
laminated. The AOD may be implemented to be thinner than a laser
direct structuring (LDS) antenna implemented through copper nickel
plating, have a low thickness dependency, and be invisible on
appearance. Also, the AOD may transmit or receive a signal directly
to or from the display 151. Thus, the AOD may be used in the mobile
terminal 100 in which the display 151 is located at both sides as
described in the present disclosure.
[0065] FIGS. 4 and 5 are exploded perspective views illustrating a
mobile terminal according to an example embodiment. Specifically,
FIG. 4 is an exploded perspective view illustrating a mobile
terminal from a front-side direction and FIG. 5 is an exploded
perspective view illustrating the mobile terminal from a rear-side
direction.
[0066] The mobile terminal 100 of the present disclosure may
include a frame, for example the first frame 101 and the second
frame 102 to mount components therein. As illustrated in FIG. 2,
the frame may be changed in size in the first direction. At least
one frame may relatively move so as to be changed in size in the
first direction. The frame may include an electronic component
mounted therein. Also, the flexible display 151 may be located
external to the frame.
[0067] Since the mobile terminal 100 of the present disclosure
includes the flexible display 151, the flexible display 151 may be
coupled in a form of covering a front side and a rear side of the
frame. The frame may include the first frame 101 and the second
frame 102 that moves relative to the first frame 101 in the first
direction. The first frame 101 and the second frame 102 may each
include a front portion, a rear portion, and a side portion and may
be coupled to each other.
[0068] The first frame 101 may correspond to a main body of the
mobile terminal 100 and have a space for accommodating components
between a first front portion 1011 and a first rear portion 1012.
Also, the first frame 101 may accommodate, in the space, the second
frame 102 that is movably coupled to the first frame 101.
Specifically, as illustrated in FIGS. 2 and 5, the first frame 101
may include the first front portion 1011 that is disposed in the
front of the mobile terminal 100 to support the front-side portion
of the display 151 and the first rear portion 1012 that is disposed
in the rear of the mobile terminal 100 so that various components
are mounted therein.
[0069] The first front portion 1011 and the first rear portion 1012
may be separated in a predetermined distance such that a
predetermined space is formed therebetween. Also, the first front
portion 1011 and the first rear portion 1012 may be connected by a
first side portion 1013. The first side portion 1013 may be
integrally formed with the first rear portion 1012 or the first
front portion 1011. The camera 121, the acoustic output part 152,
an input and output terminal, the controller 180, and the power
supply 190 may be accommodated in the space of the first frame 101
as components of the mobile terminal 100. For example, the
controller 180 may be a circuit board 181 including an electric
circuit and a processor provided to control an operation of the
mobile terminal 100. In addition, the power supply 190 may be a
battery 191 and related components. Also, the below-described
driving part 200 that controls a slide movement of the second frame
102 may be accommodated in the first frame 101.
[0070] As described above, the display 151 may have a continuous
body and rolled in the mobile terminal 100 to be located both front
side and rear side of the mobile terminal 100. The display 151 may
include a front-side portion located at the front side of the
mobile terminal 100, a rear-side portion located at the rear side
of the mobile terminal 100, and a side portion located between the
front-side portion and the rear-side portion to cover a side
surface of the mobile terminal 100. The front-side portion and the
rear-side portion of the display 151 may be flat and the side
portion of the display 151 may be curved. When the side portion is
bent to form an angle, the flexible display 151 may be damaged.
Thus, the side portion may be provided to be bent with a
predetermined curvature.
[0071] The display 151 may include a fixed portion and a variable
portion. The fixed portion may be a portion fixed to a frame. Since
the fixed portion is fixed at the frame, a bending degree of the
fixed portion may not be changed so that the fixed portion is
maintained in a predetermined shape. The variable portion may be a
portion in which an angle or position of a bent portion is
changeable. The variable portion may require a structure for
supporting a rear surface of the variable portion in in accordance
with a change in angle or position of the bent portion.
[0072] The fixed portion may be coupled to the first frame 101 of
the display 151 and located at the front side so as to be a part of
the front-side portion. The variable portion may include a side
portion located in a direction to a side surface of the mobile
terminal. In this case, a position of the side portion may be
changed based on a position of the second frame 102. An area
located at the front side and an area located at the rear side may
be changed in size based on the side portion. For example, based on
whether being in the first state or the second state, a portion of
the variable portion may be the front-side portion and another
portion may be the rear-side portion. The variable portion may be
located in the first direction with respect to the fixed portion
(e.g., a first area 151a and a second area 151b) based on the
mobile terminal 100. An end portion of the variable portion may be
bent in a direction to the rear side of the mobile terminal 100 and
slidably move on the rear side of the second frame 102.
[0073] The end portion of the variable portion of the display 151
may be coupled to a sliding frame 103 that guides the end portion
to slide on the rear side of the second frame. The sliding frame
103 may move on the second frame 102 in the first direction
simultaneously when the second frame 102 moves in the first
direction. As a result, the sliding frame 103 may move relative to
the first frame 101 by a distance twice that of the second frame
102. Referring to FIG. 3, the first rear portion 1012 of the mobile
terminal 100 may include an exposed rear portion 1015 that is not
covered by the display 151 and is exposed outside even in the first
state. In the exposed rear portion 1015, various buttons for
manipulating the mobile terminal 100, switches, the camera 121, the
physical input part 120 such as a flash, and the sensing part 140
such as the proximity sensor 141 and a fingerprint sensor may be
arranged. The first rear portion 1012 except the exposed rear
portion 1015 may be covered by display 151 in the first state as
shown in (a) of FIG. 3 and exposed in the rear-side direction in
the second state as shown in (b) of FIG. 3.
[0074] A typical bar-type terminal may provide a display on only a
front side of the terminal. In such terminal, a main camera may be
mounted on a rear side of the terminal to allow a user to capture
an object facing a side opposite to the display while the user is
viewing the object through the display. To allow the user to
capture himself or herself while viewing through the display,
another camera may be additionally required on a front side of the
terminal.
[0075] In the present disclosure, the display 151 may be located at
both front side and rear side of the mobile terminal 100. When the
user captures himself or herself, the display 151 on the same side
as the camera 121, that is, the rear-side portion of the display
151 may be used. When the user captures an object facing the side
opposite to the user, the front-side portion of the display 151
located on the side opposite to the camera 121 may be used. Through
this, the mobile terminal 100 may capture the user and the object
facing the side opposite to the user using the single camera 121.
The camera 121 may include a plurality of cameras having different
angles of view such as a wide angle, an ultra-wide angle, a
telephoto, and the like. In addition to the camera 121, a proximity
sensor, an acoustic output part, and the like may be located on the
exposed rear portion 1015. Also, the antenna 116 may be installed
thereto. In view of exterior design, an exposure decoration may be
attached to protect the camera and sensor of the exposed rear
portion 1015. In the exposure decoration, a portion corresponding
to the camera 121 or the sensing part 140 may be configured to be
transparent and another portion may have a predetermined pattern or
color in consideration of design so internal components are not be
exposed.
[0076] The first side portion 1013 may extend along edges of the
first front portion 1011 and the first rear portion 1012 to cover a
perimeter of the first frame 101 and form an appearance of the
mobile terminal 100. As described above, since the second frame 102
is accommodated in the first frame 101 and movably coupled thereto,
a portion of the first frame 101 may be open to allow a relative
movement of the second frame 102 with respect to the first frame
101.
[0077] Referring to FIG. 2, because the second frame 102 is movably
coupled to the first frame 101 in the first direction, the first
side portion 1013 may not be formed on the first-direction side
surface and thus, may be open. Since the first side portion 1013 is
exposed external to the mobile terminal 100, the interface 160 for
connecting a power port or an ear jack, or the user input part 120
such as a volume button may be disposed therein. When including a
metal material, the first side portion 1013 may serve as an
antenna.
[0078] The second frame 102 may include a second front portion 1021
located in the front of the mobile terminal 100 and a second rear
portion 1022 located in the rear of the mobile terminal 100. Like
the first front portion 1011 and the first rear portion 1012 of the
first frame 101, the second front portion 1021 and the second rear
portion 1022 may be formed as substantially flat panel members. The
second frame 102 may accommodate various components and may not
interfere with the components accommodated in the first frame 101
during the movement. The second front portion 1021 and the second
rear portion 1022 may be coupled to each other so that a
predetermined space is formed therebetween. Also, the second front
portion 1021 and the second rear portion 1022 may be shaped not to
interfere with the components included in the first frame 101.
[0079] FIG. 6 illustrates side views of the mobile terminal 100
from the third direction. FIG. 6 illustrates the first side portion
1013 of the first frame 101 and a second side portion 1023 of the
second frame 102. A first-direction end portion of the second frame
102 may not be exposed outside since the flexible display 151 is
located. Also, a second-direction end portion of the second frame
102 may be open to prevent interference with the first frame 101.
The second side portion 1023 of the second frame 102 located in the
third direction (in the drawings, an upper or lower direction or
including both upper and lower directions) may overlap the first
side portion 1013 of the first frame 101 not to be exposed outside
in the first state. In the second state, however, the second side
portion 1023 may be exposed outside because the second frame 102 is
pulled out.
[0080] The display 151 may be rolled in the second frame 102 and
bent at 180.degree. so as to be located at both front and rear
sides of the mobile terminal 100. For such arrangement of the
display 151, the second frame 102 may include a roller 210
rotatably disposed therein. The roller 210 may be disposed at a
predetermined position in the second frame 102. To provide a
high-quality display to a user, the display 151 may be flatly
spread on the front side and the rear side of the mobile terminal
100. For this, a sufficient tensile force may be provided to the
display 151. To provide the sufficient tensile force, the roller
210 may be disposed at the first-direction end portion of the
second frame 102. The roller 210 may be extended in the second
direction and rotatably coupled to the second frame 102.
[0081] The display 151 may be gently bent with a predetermined
curvature to be rolled on the roller 210. The flexible display 151
may include a first surface exposed outside to display an image and
an inner surface facing a frame on the other side. The roller 210
may be installed in the second frame 102 to be freely rotatable
while contacting the inner surface of the display 151. Practically,
the roller 210 may move the display 151 in a lateral direction,
that is, a direction vertical to a longitudinal direction of the
mobile terminal 100. As described below, when the second frame 102
slides, the display 151 having a direction (e.g., the first
direction D1 or the second direction D2) different from and
relative to the second frame 102 may be moved to the front side or
the rear side of the mobile terminal 100 by the tensile force
applied from the second frame 102. In this instance, the roller 210
may guide the movement of the display 151 while rotating.
[0082] The roller 210 may be disposed adjacent to the
first-direction end portion of the second frame 102 and include a
side frame 1024 disposed at the first-direction end portion of the
second frame 102 to prevent damage to the display 151 rolled on the
roller 210.
[0083] The side frame 1024 may extend in the longitudinal direction
of the second frame 102 (e.g., the third direction) to cover the
first-direction side portion, so as to protect the roller 210 and
the display 151 rolled thereon. Also, the side frame 1024 may be
relocated based on a state of the mobile terminal 100. The side
portion may have a predetermined curvature and be rolled by the
roller 210. An inner surface of the side frame 1024 may include a
curved surface corresponding to the curvature of the side
portion.
[0084] The side frame 1024 may substantially form an appearance of
the mobile terminal 100 along with the first side portion 1013 of
the first frame 101. Also, to minimize interference with the
components of the first frame 101 during the movement, a
second-direction side portion of the second frame 102 may be
omitted.
[0085] During expansion and retraction in the first direction D1
and the second direction D2, the second frame 102 may overlap the
first frame 101, for example, the first front portion 1011 and the
first rear portion 1012 of the first frame 101 to prevent the
interference with the first frame 101. Specifically, as described
above, the display 151 may be coupled to the first front portion
1011 of the first frame 101 and supported by the first front
portion 1011. Thus, the display 151 may not be additionally
supported by the second front portion 1021 of the second frame
102.
[0086] When the second front portion 1021 is located between the
first front portion 1011 and the display 151, the display 151 may
be deformed or damaged due to a friction with the second front
portion 1021 moving repetitively. To prevent this, the second front
portion 1021 may be disposed below the first front portion 1011 or
inserted between the first front portion 1011 provided as two
pieces. The second rear portion 1022 of the second frame 102 may be
disposed in a rear-side direction of the first rear portion 1012 of
the first frame 101. For example, a front side of the second rear
portion 1022 may face a rear side of the first rear portion 1012.
Also, to stably support a motion of the second frame 102, the rear
side of the first rear portion 1012 may contact the front side of
the second rear portion 1022. In such arrangement, the second rear
portion 1022 may be exposed external to the first frame 101, for
example, external to the first rear portion 1012 and coupled to the
display 151.
[0087] The second frame 102 may extend and retract in the first and
second directions D1 and D2 such that a size of the mobile terminal
100, for example, a size of the front side of the mobile terminal
100 is increased or reduced. In this instance, to obtain the
intended first and second states, the display 151 may be moved
based on the increased or reduced portion of the front side. When
the display 151 is fixed to the second frame 102, the display 151
may not be moved in response to the front side of the mobile
terminal 100 being extended or retracted. For this reason, the
display 151 may be movably coupled to the second frame 102.
[0088] Specifically, the display 151 may include the first area
151a located at the front side of the mobile terminal 100 and the
second area 151b coupled to the sliding frame 103 located at the
rear side of the mobile terminal 100. The display 151 may also
include a third area 151c located between the first area 151a and
the second area 151b. The third area 151c may be bent to cover the
roller 210 and may move to the front side or the rear side based on
a state change of the mobile terminal 100. The sliding frame 103
may be provided as a panel-type member that extends in the
longitudinal direction of the mobile terminal 100 (e.g., the third
direction) and may be coupled to the second rear portion 1022 to be
movable in the first direction D1 and the second direction D2.
[0089] The first area 151a, the second area 151b, and the third
area 151c may be connected to one another and form a continuous
body of the display 151. Also, as described above, to allow the
third area 151c to move to the front side or the rear side of the
mobile terminal 100 based on a moving direction of the second frame
102, the first area 151a may be unmovably fixed to the front side
of the mobile terminal 100 and the second area 151b may be movably
provided on the rear side of the mobile terminal 100. Such
configuration of the display 151 will be described in detail
below.
[0090] The first area 151a may be located at the front side of the
mobile terminal 100, for example, the front side of the first front
portion 1011 of the first frame 101. The first area 151a may be
fixed to the front side of the first frame 101, for example, the
front side of the first front portion 1011 so as not to move even
when the second frame 102 moves. Through this, the first area 151a
may always be exposed at the front side of the mobile terminal
100.
[0091] The third area 151c may be adjacent to the first area 151a.
The third area 151c may extend into the second frame 102 to be
rolled on the roller 210. Continually, the third area 151c may
extend out of the second frame 102 and partially cover the second
frame 102, for example, the rear side of the second rear portion
1022. Meanwhile, since the second frame 102, that is, the second
rear portion 1022 is adjacent to the first frame 101, for example,
the first rear portion 1012 and forms a rear case of the mobile
terminal 100 together, it can be understood that the third area
151c is also arranged at the rear side of the first frame 101.
[0092] The second area 151b may be adjacent to the third area 151c
and located at the rear side of the mobile terminal 100, for
example, the rear side of the second rear portion 1022 of the
second frame 102. The second area 151b may be coupled to the
sliding frame 103 instead of being coupled directly to the second
frame 102.
[0093] As a result, the first area 151a may be located at the front
side of the mobile terminal 100 to be always exposed at the front
side irrespective of the movement of the second frame 102. Also,
the second area 151b may be located at the rear side of the mobile
terminal 100 to be always exposed at the rear side irrespective of
the movement of the second frame 102. The third area 151c may be
between the first and second areas 151a and 151b and selectively
arranged at the front side or the rear side of the mobile terminal
100 based on the moving direction (e.g., D1, D2) of the second
frame 102.
[0094] In such a selective arrangement of the third area 151c,
since the third area 151c moves to the front side of the mobile
terminal 100 and the second rear portion 1022 moves in the first
direction D1 in the second state, a first rear portion 1012's
portion which is covered by the second area 151b and the third area
151c of the display 151 and the second rear portion 1022 in the
first state may be exposed external to the mobile terminal 100.
Also, in the first state, the second front portion 1021 of the
second frame 102 may be disposed hidden by the first front portion
1011 of the first frame 101. In the second state, however, the
second front portion 1021 may be moved out of the first frame 101
to support the third area 151c of the display 151 located at the
front side of the mobile terminal 100.
[0095] A separating plate may be further provided to prevent the
second front portion 1021 from affecting inside components during
the sliding movement. The separating plate may be located in a
rear-side direction of the second front portion 1021 and coupled to
the first front portion 1011. The second front portion 1021 may
move between the first front portion 1011 and the separating plate
in response to the slide movement of the second frame 102.
[0096] The third area 151c may be rolled on the roller 210 in the
second frame 102 to be curved. When the first state is changed to
the second state, the third area 151c may extend from the second
frame 102 to the front side of the mobile terminal 100 while being
rolled on the roller 210 in one direction. When the second state is
changed to the first state, the third area 151c may be rolled on
the roller 210 in a reverse direction to retract from the front
side of the mobile terminal 100 to the second frame 102.
Simultaneously, the third area 151c may return from the second
frame 102 to the rear side of the mobile terminal 100.
[0097] An opening-book-type foldable mobile terminal may be
repetitively folded at a predetermined position and thus, easily
damaged at the position. In contrast, a deformed portion of the
flexible display 151, that is, a portion to be rolled on the roller
210 may vary based on the first and second state of the mobile
terminal 100, that is, the movement of the second frame 102. As
such, the mobile terminal 100 of the present disclosure may
significantly reduce deformation and fatigue repetitively applied
to a predetermined portion of the display 151 so that the damage to
the display 151 is prevented.
[0098] Based on the above-described configuration, an overall
operation of the mobile terminal 100 will be described as follows.
In one example, a state transition may be performed manually by a
user, and an operation of the mobile terminal 100 performed during
such a manual state transition will be described. However, the
below-described operations of the first to third frames 101 to 103
and the display 151 may be equally performed even when a power
source other than user's power is used, for example, the driving
part 200 is applied as described later.
[0099] A rear cover 1025 may be further provided on the rear side
of the second rear portion 1022 to prevent an external exposure of
the rear-side portion of the display 151 located at the rear side
of the mobile terminal 100. When the rear cover 1025 includes a
transparent material, the rear-side portion may also be used even
in the first state. When an opaque material is used for the rear
cover 1025, the rear cover 1025 may cover the sliding frame 103
such that the moving of the sliding frame 103 is not exposed
outside. The sliding frame 103 and the second and third areas of
the display 151 may move in the first direction and the second
direction in a space between the second rear portion 1022 and the
rear cover 1025.
[0100] FIG. 7 illustrates the driving part 200 of the mobile
terminal 100 according to an example embodiment. The mobile
terminal 100 of the present disclosure may change a state of the
mobile terminal 100 using a method in which a user manually pulls
the second frame 102 out of the first frame 101 in the first
direction or pushes the second frame 102 into the first frame 101
in the second direction. However, the manual method may cause
damage when an excessive force is applied to a main body of the
mobile terminal 100. Thus, the mobile terminal 100 may further
include the driving part 200 using a motor 201 to stably move the
second frame 102 without twisting.
[0101] The motor 201 may use the motor 201 that provides a rotating
force as illustrated in FIG. 7 and may also use a linear motor that
performs a rectilinear motion. To increase the rotating force
provided by the motor 201, a diameter of the motor 201 may also be
increased. Referring to FIG. 7, two motors 201 may be used to
provide a predetermined intensity of driving force or more while
preventing an increase in thickness in a restricted space of the
mobile terminal 100. The second frame 102 moving too fast may lead
to damage or false operation. Thus, a planetary gear may be further
provided to reduce the speed of the motor 201 so the motor 201
moves at a stable speed. A planetary gear 202 may serve to amplify
or attenuate a number of revolutions of the motor 201 using a
plurality of disc gears with different numbers of teeth.
[0102] The motor 201 may be fixed to the first frame 101 as shown
in (a) of FIG. 7. Also, as shown in (b) of FIG. 7, a position of
the motor 201 may be fixed even when the mobile terminal 100 enters
the second state in response to the second frame 102 moving in the
first direction.
[0103] Since the second frame 102 linearly moves in the first
direction or the second direction with respect to the first frame
101, a rack and pinion that converts a rotating force of the motor
201 into the linear motion may be used. A pinion gear receiving the
rotating force of the motor 201 may be arranged to engage with a
rack gear 205 having teeth consecutively arranged in the first
direction. The pinion gear may be fixed to the first frame 101
along with the motor 201, and the rack gear 205 may be located at
the second frame 102. Conversely, the first frame 101 may also be
located at the rack gear 205, and the pinion gear may also be
located at the second frame 102 along with the motor 201. Since the
pinion gear is caught by the motor 201 so as not to rotate, the
second frame 102 may be maintained in the first state and the
second state. However, when a large external force is applied, the
pinion gear may rotate, which may lead to a displacement of the
second frame 102.
[0104] Although not shown, a stopper may be further provided to fix
a position between the first frame 101 and the rack gear 205 or the
second frame 102 so the mobile terminal 100 is fixedly in the first
state or the second state. When the motor 201 is driven in response
to current being applied, the stopper may be released to allow
movement of the second frame 102. When current is not applied so
the motor 201 does not rotate, the stopper may be engaged to fix
the second frame 102 and a position of the second frame 102.
[0105] When the driving part 200 is provided as a pair of driving
parts symmetrically disposed in a vertical direction (e.g., the
third direction) the driving part 200 may stably move. However, to
arrange a battery and the like in consideration of a limited
mounting space of the mobile terminal 100, the driving part 200 may
be disposed biasedly on one side as shown in (a) of FIG. 7. In some
cases, due to such an asymmetric position of the driving part 200,
an upper portion and a lower portion of the second frame 102 may
move at different speeds so the second frame 102 is twisted. To
prevent this, a linear guide 230 may be further provided in the
mobile terminal 100.
[0106] The linear guides 230 may be provided in both
third-direction ends, for example, an upper side and a lower side
of the mobile terminal 100 to complement a function of the driving
part 200 disposed biasedly on the one side. The linear guide 230
may include a guide rail 231 extended in the first direction and a
guide block 232 moving along the guide rail 231. The guide rail 231
may be disposed on the first frame 101 and the guide block 232 may
be disposed on the second frame 102, and vice versa. In the present
embodiment, the guide rail 231 may be disposed on the second frame
102 to cover upper and lower side surfaces of an extended portion
of the second frame 102 in the second state.
[0107] The guide block 232 may be coupled to the first frame 101,
the guide rail 231 may be coupled to the second frame 102, and then
the guide block 232 and the guide rail 231 may be slidably coupled.
For the convenience of installation, in a state of the guide block
232 and the guide rail 231 are coupled, the guide block 232 may be
fixed to the first frame 101, and then the second frame 102 may be
coupled to the guide rail 231.
[0108] The guide block 232 may include a guide groove into which
the guide rail 231 is inserted. The guide rail 231 may include a
rail groove into which a portion of the guide block 232 is
inserted. Projections may be formed on a fastening portion of the
guide block 232 and the guide rail 231 so the guide rail 231 and
the guide block 232 move in the first direction or the second
direction without deviating in a thickness direction of the mobile
terminal 100. To reduce a friction between the guide block 232 and
the guide rail 231, a member formed of a material having a high
wear resistance, a low friction resistance, and a self-lubricating
property such as polyoxymethylene (POM) or a bearing may be added
inside the guide groove.
[0109] FIG. 8 illustrates cross-sectional views taken along lines
A-A and B-B of FIG. 2. Specifically, (a) of FIG. 8 is a
cross-sectional view taken along the line A-A of FIG. 2 and (b) of
FIG. 8 is a cross-sectional view taken along the line of FIG. 2. As
illustrated in FIG. 2, when the second frame 102 moves in the first
direction and enters the second state, the third area 151c located
in the rear-side direction may move in the front-side direction. In
this case, a structure for supporting the rear side of the third
area 151c moved to the front side may be required. The second front
portion 1021 located at the front side of the second frame 102 may
be located at the rear side of the third area 151c in the second
state. However, because the second front portion 1021 may overlap
the first front portion 1011 of the first frame 101 in the first
state, the first front portion 1011 and the second front portion
1021 may have a level difference therebetween. The level difference
between the first front portion 1011 and the second front portion
1021 may create a boundary between the first area 151a and the
third area 151c of the flexible display 151. A rolling plate 104
may be used as a support structure for filling a space between the
second front portion 1021 and the third area 151c of the flexible
display 151.
[0110] The rolling plate 104 may be located at the rear side of the
flexible display 151 and may have a thickness corresponding to a
space between the second front portion 1021 and the flexible
display 151 in the second state. As shown in (a) of FIG. 8, in the
first state, the rolling plate 104 may be rolled on the roller 210
and located in a direction to the side surface and the rear side of
the mobile terminal 100. Also, the flexible display 151 and the
rolling plate 104 may be located between the rear cover 1025
covering the rear-side portion of the display 151 and the second
rear portion of the second frame 102. As shown in (b) of FIG. 8,
when switching to the second state, the rolling plate 104 may move
to the front side and thus, located in a front portion of the
second frame 102.
[0111] The third area 151c in which the rolling plate 104 is
located may be a portion in which bending deformation occurs when
the first state is changed to the second state. Thus, the rolling
plate 104 may be deformed based on the deformation of the third
area 151c. Simultaneously, the rolling plate 104 may have a
predetermined stiffness such that the flexible display 151 is
maintained as being flat when the flexible display 151 is located
at the front side or the rear side. As such, the rolling plate 104
may require a structure to be maintained as being flat in the third
direction and to be bending-deformable in the first direction.
[0112] FIG. 9 illustrates the rolling plate 104 and the display 151
of the mobile terminal 100 according to an example embodiment. The
rolling plate 104 may include a plurality of support bars 1041
extended in the third direction. The plurality of support bars 1041
may be arranged in parallel in the first direction at preset
intervals. Through such arrangement, even when the flexible display
151 is rolled on the roller 210 to be bent, the plurality of
support bars 1041 may be prevented from interfering with each
other. The support bar 1041 may be implemented as an
injection-molded object having a predetermined thickness to achieve
the stiffness and may include a metal material such as stainless
steel (SUS), for example.
[0113] The plurality of support bars 1041 may be directly attached
to the rear side of the display 151. In this case, however, it may
take a long time and a lot of defects, which may decrease
productivity. Also, in a case of directly processing the display
151, the display 151 may be easily damaged. To prevent this, the
mobile terminal 100 may further include a rolling sheet 1045 to fix
the plurality of support bars 1041. The rolling sheet 1045 may
include a metal material, and may use a material having
ultra-elasticity to be bending-deformed and maintained as being
flat after the bending deformation.
[0114] For example, an ultra-elastic metal sheet such as a thin STS
sheet having a thickness of 0.05 millimeters (mm) or less may be
used. To attach the support bar 1041 to the rolling sheet 1045 and
attach the rolling sheet 1045 to the rear side of the display 151,
an adhesive tape may be applied to both sides of the rolling sheet
1045.
[0115] The rolling sheet 1045 may have a kerf pattern in which a
groove extending in the third direction is provided in plural in
the first direction. The grooves of the kerf pattern may be formed
between the plurality of support bars 1041. Also, desirably, the
grooves may be formed in a side on which the support bars 1041 are
attached to the rolling sheet 1045. The kerf pattern may be formed
in a wedge shape such that a size is large in a surface part of the
rolling sheet 1045 and narrowed gradually.
[0116] Instead of using the rolling sheet 1045, a material having
elasticity such as silicon may be disposed between the support bars
1041 to couple the neighboring support bars 1041 so an angle
between the support bars 1041 varies. An elastic connecting part
may be bent at a position corresponding to the roller 210 and if
located at the front side or the rear side, may stretch so that the
support bars 1041 are arranged to form a plane.
[0117] The support bars 1041 may form a flat plane corresponding to
the rear side of the display 151. Also, as shown in (b) of FIG. 8,
the support bars 1041 may form a curved plane with a predetermined
curvature. The support bars 1041 of the curved plane may be in
close contact with a curved surface of the roller 210 when the
rolling plate 104 is rolled on the roller 210.
[0118] In some cases, the support bars 1041 may form a plane having
one flat surface in contact with the display 151 and the other
surface curved with a curvature corresponding to the curvature of
the roller 210. In such cases, the support bars 1041 may have
maximal thicknesses at a first-directional end and a
second-directional end and have a minimum thickness at a
center.
[0119] The rolling plate 104 may be located at a position
corresponding to the third area 151c, and rolled and bent over the
roller 210 to span the front side and the rear side. The rolling
plate 104 may be connected to the first front portion 1011 of the
first frame 101 in the front-side direction and connected to the
sliding frame 103 in the rear-side direction. In order for the
flexible display 151 to form a continuous surface without a level
difference, the first front portion 1011 of the first frame 101
located at the rear side of the first area 151a, the sliding frame
103 located at the rear side of the second area 151b, and the
rolling plate 104 located at the rear side of the third area 151c
may contact the display 151 at the same height. For example, since
the sliding frame 103 moves on the rear side of the mobile terminal
100 and moves in the same space as the rolling plate 104, the
rolling plate 104 may have a thickness corresponding to that of the
sliding frame 103.
[0120] FIGS. 10 and 11 illustrate a mobile terminal according to an
example embodiment of the present disclosure. Specifically, FIGS.
10 and 11 illustrate screens displayed on a mobile terminal in
response to a received input and a size change of a display.
[0121] Referring to FIG. 10, a first screen 1001 may be displayed
on a first side (e.g., a front side) of a mobile terminal. The
first screen 1001 may include content A of a first application and
content B of a second application provided based on executions of
the first application and the second application. Also, the content
A and the content B may include distinguishable contents provided
in the same application. For example, when a video is provided in a
specific application, the video may be included in an area A and
addition information associated with the video may be displayed in
an area B.
[0122] A size by which the display is located at the first side may
be reduced. In response to the size reduction, a second screen 1002
may be displayed on the first side. In this case, at least a
portion of the display may be located at a second side (e.g., a
rear side) facing the first side.
[0123] In response to at least a portion of an area of the display
located at the first side being relocated to another side, the
mobile terminal may suspend displaying at least a portion of
content corresponding to an area located at the other side. As an
example, when a portion of an area of the display is positioned to
the second side, the mobile terminal may suspend displaying the
content B in the second screen 1002 and a third screen 1003. As
another example, when an area including the content B corresponding
to the third screen 1003 in the display is arranged on the second
side, the mobile terminal may suspend displaying content displayed
in the area on the second side, for example, the content B
corresponding to the third screen 1003.
[0124] In response to at least a portion of an area of the display
located at the first side being relocated to another side, the
mobile terminal may display a separate layer to overlap at least a
portion of content corresponding to the at least the portion of the
area. For example, when a portion of the area of the display is
located at the second side, the mobile terminal may display a
separate layer to overlap the content B of the third screen
1003.
[0125] In some cases, the suspension of displaying the content
corresponding to the portion located at the other side or the
displaying of the separate layer may be performed after the size
reduction of the display is completed. In such cases, since the
second screen 1002 and the third screen 1003 are screens displayed
during the size reduction of the display, the displaying of the
content B may be maintained as illustrated. However, embodiments
are not limited thereto. For example, the suspension of displaying
the content on the area located at the second side or the
displaying of the overlapping separate layer may be performed in
real time. The separate layer may be a layer having a transparency,
so that content below the layer is viewed through the layer.
[0126] Referring to FIG. 10, the area corresponding to the content
B in the area of the display may be located at the second side so
the size reduction of the display located at the first side is
completed. In response to the completion, a fourth screen 1004 may
be displayed on the first side and a fifth screen 1005 may be
displayed on the second side. Here, the fifth screen 1005 may be a
screen in which a separate layer is superimposed on the content B,
but is not limited thereto. The fifth screen 1005 may include a
screen in which displaying of the separate layer is omitted in
accordance with the suspension of displaying the content B, a
locked screen, or a screen for which touch input sensing is
inactivated.
[0127] The mobile terminal may provide an icon 1010 indicating
related content on the first side in response to a size change (or
size reduction) of the display. For example, in a case in which the
area corresponding to the content B is located on the second side
and the separate layer is displayed to overlap the content B, or
the displaying of the content B is suspended, the icon 1010 related
to the content B may be displayed as shown in the fourth screen
1004. The icon 1010 may include an icon of an application that
provides the content B, for example, an icon of the second
application.
[0128] The suspension of displaying the content or the overlapping
displaying of the separate layer may be maintained for a
predetermined period of time. In this case, the mobile terminal may
provide information on the predetermined period of time around the
icon 1010 as shown in the fourth screen 1004. Specifically, the
mobile terminal may provide the information on the predetermined
period of time by displaying an image representing a lapse of the
predetermined period of time on a perimeter of the icon 1010.
However, it is merely provided as an example and the information on
the predetermined period of time may be provided in various forms.
Related examples will be described with reference to FIG. 22 or
23.
[0129] When a first input to the icon 1010 is applied within the
predetermined period of time, the content B may be displayed in an
area corresponding to the first input. Specifically, when the first
input to the icon 1010 is applied within the predetermined period
of time, the content B may be displayed in an area in which the
icon 1010 is displayed on the first side, that is, an area in which
the content A is displayed. For example, a sixth screen 1006 may be
displayed on the first side. In response to the first input, a
seventh screen 1007 may appear on the second side. The seventh
screen 1007 may be a locked screen, an empty screen, or a screen
for providing information based on an always on display (AOD).
[0130] The mobile terminal may be set to terminate an application
related to content or drive the application in a background region
when the predetermined period of time elapses without receiving an
input. Referring to FIG. 10, for example, when the predetermined
period of time elapses without receiving an input to the icon 1010,
the mobile terminal may terminate the second application providing
the content B. Through this, the displaying of the content B may be
terminated.
[0131] As described with reference to FIG. 10, even if a portion of
an area in which content is displayed moves to the rear side in
response to a display size reduction while a user is using the
content provided on the front side of the mobile terminal, it is
possible to easily use the content used on a screen of the front
side without making an additional motion of turning the mobile
terminal or moving to a home screen to re-execute an application on
the front side.
[0132] Although not shown, in some cases, the displaying of the
icon 1010 may be omitted. In such cases, when a predetermined first
input is applied instead of the input to the icon 1010, the content
B may be displayed in an area corresponding to the first input. An
example related to the predetermined first input will be described
with reference to FIG. 14.
[0133] FIG. 11 illustrates a case in which an input (e.g., a second
input) different from the input to the icon 1010 of FIG. 10 is
received. A first screen 1101 of FIG. 11 may correspond to the
fourth screen 1004 of FIG. 10. A second screen 1102 of FIG. 11 may
correspond to the fifth screen 1005 of FIG. 10.
[0134] Referring to FIG. 11, a second input (e.g., a touch input to
the second side) may be received in a state in which the first
screen 1101 is displayed on a first side of a mobile terminal and
the second screen 1102 is displayed on a second side. In this case,
content B may be displayed in an area corresponding to the second
input. For example, a fourth screen 1104 including the content B
may be displayed on the second side. In response to the fourth
screen 1104 being displayed, a third screen 1103 may be displayed
on the first side.
[0135] As illustrated in FIG. 11, the third screen 1103 may include
a screen in which a separate layer overlaps content A but is not
limited thereto. In some cases, the third screen 1103 may include a
screen in which the displaying of the content A and the separate
layer is omitted, a locked screen, a screen for providing
information based on an AOD, or a screen for which touch input
sensing is inactivated. The fourth screen 1104 may include a screen
on which the content B is displayed.
[0136] When the second input is received, a fifth screen 1105 may
be displayed on the first side and a sixth screen 1106 may be
displayed on the second side. For example, the content B may be
displayed on the second side in a state in which the displaying of
the content A is maintained on a screen of the first side.
[0137] The first input of FIG. 10 and the second input of FIG. 11
are not limited to the foregoing examples and may include
predetermined inputs distinguished from each other. As an example,
the first input may include a swipe input of a first direction and
the second input may include a swipe input of a second direction.
As another example, the first input may include a touch input to a
first position and the second input may include a touch input to a
second position. As another example, the first input may include a
left-direction swipe input applied to the icon 1010 and the second
input may include a right-direction swipe input applied to the icon
1010.
[0138] FIG. 12 is a functional block diagram illustrating a mobile
terminal according to an example embodiment of the present
disclosure. As described below, an element of a mobile terminal
1200 may be a unit that processes at least one function or
operation and may be implemented through hardware, software, or a
combination of hardware and software.
[0139] Referring to FIG. 12, the mobile terminal 1200 may include a
display 1201 and a controller (or processor) 1202.
[0140] The display 1201 may be located to be changed in size by
which the display 1201 is exposed at a first side of the mobile
terminal 1200 (e.g., a front side of the mobile terminal 1200). The
size by which the display 1201 is exposed at the first side may be
changed based on a control of the controller 1202 described
below.
[0141] A portion of the display 1201 may be located at the first
side of the mobile terminal 1200 and another portion may be located
at another side of the mobile terminal 1200 (e.g., a rear side or a
side surface of the mobile terminal 1200). As an example, a second
area of the display 1201 may be located at the first side of the
mobile terminal 1200 and a first area of the display 1201 may be
located at the second side facing the first side. As another
example, the second area of the display 1201 may be located at the
first side of the mobile terminal 1200, and at least a portion of
the first area of the display 1201 may be arranged on a third side
that is located between the first side and the second side and
wound on one side of the mobile terminal 1200.
[0142] A portion of the display 1201 may be located at the first
side, and another portion may be wound on one side of the mobile
terminal 1200 and located at the second side of the mobile terminal
1200. Specifically, the display 1201 may be bent at one end
adjoining with the first side, have at least a portion located at
the first side, and have at least another portion located at the
second side adjoining with the one end. However, embodiments are
not limited thereto. The display 1201 may be divided into a
plurality of areas connected using hinges. The display 1201 may be
arranged such that one area of the plurality of areas is fixedly
located at the first side and another area is located at the first
side or the second side based on hinge driving.
[0143] A variety of information associated with an operation of the
mobile terminal 1200 may be displayed on the display 1201. For
example, an icon of an application or content of the application
provided based on an execution of the application may be displayed
on the display 1201. Here, the icon of the application may include
an icon to which an input is applied for execution of the
application. Also, the content of the application may include
various contents related to a function of the application provided
when the application is executed.
[0144] The controller 1202 may control the mobile terminal 1200 or
an element of the mobile terminal 1200. For example, the controller
1202 may execute application programs or instructions stored in a
memory, thereby controlling an operation of the display 1201.
[0145] The controller 1202 may display the content of the first
application in the first area of the display 1201 located at the
first side based on the execution of the first application. The
first area may include at least a portion of the display 1201
located at the first side. The content of the first application is
content provided by the first application. For example, when the
first application is a photo album application, content provided by
the first application may be an image representing pictures.
[0146] The controller 1202 may execute a plurality of applications.
In this case, the controller 1202 may display content of each of
the applications. For example, based on execution of the first
application and the second application, the controller 1202 may
display the content of the first application in the first area of
the first side of the display 1201 and display content of the
second application in the second area of the first side.
[0147] The controller 1202 may arrange at least a portion of the
first area of the display 1201 on another side. For example, the
controller 1202 may move at least a portion of the first area of
the display 1201 to another side (e.g., the second side facing the
first side or a third side located between the first side and the
second side and wound at one side of the mobile terminal 1200) in
response to a size reduction of the display 1201 located at the
first side. Through this, at least a portion of the first area may
be located at the other side.
[0148] The controller 1202 may suspend displaying at least a
portion of the content included in the first area in response to
the at least the portion of the first area being arranged on the
other side. As an example, the controller 1202 may suspend
displaying the content in the first area when the first area is
relocated from the first side to the second side due to the size
reduction of the display 1201 located at the first side. As another
example, when the first area is relocated from the first side to
the second side due to the size reduction of the display 1201
located at the first side, the controller 1202 may suspend
displaying the content in the first area and then switch the first
area to a locked screen or display an AOD screen.
[0149] The controller 1202 may display a separate layer to overlap
at least a portion of the content in response to at least a portion
of the first area being located at the other side. Specifically,
when at least a portion of the first area of the display 1201
located at the first side is located to another side, the
controller 1202 may display a separate layer to overlap at least a
portion of the content displayed in the first area. For example,
the controller 1202 may display the separate layer to fully overlap
the content displayed in the first area in response to the first
area being located at the second side due to the size reduction of
the display 1201 on the first side. Here, the separate layer may
include an image having a predetermined transparency value but is
not limited thereto, and may be implemented in various ways.
[0150] In response to at least a portion of the first area being
located at the other side, the controller 1202 may deactivate touch
input sensing for an area located at the other side. For example,
when at least a portion of the first area is located at the second
side, the controller 1202 may deactivate touch input sensing of the
second side (or the first area located at the second side).
[0151] The controller 1202 may display an icon related to the first
application on the display located at the first side in response to
the first area being located the other side. For example, when the
display 1201 of the first side includes the first area and the
second area, and when the first area is located at the second side
in response to the size reduction of the display 1201, the
controller 1202 may display the icon related to the first
application in the second area. Here, the first application may be
an application that provides content displayed in the first area as
described above and the icon related to the first application may
include an icon indicating the first application.
[0152] The controller 1202 may display the icon related to the
first application based on a position of the first area. When the
display 1201 of the first side includes the first area and the
second area, the controller 1202 may display the icon related to
the first application in a portion of an area of the second area in
response to the first area moving to the second side. The area of
the second area may be close to an area in which the first area is
previously positioned. For example, the first area may be located
in a right portion of the first side and the second area may be
located in a left portion of the first area to be in contact with
the first area. In this example, when the first area is moved to
the second side, the controller 1202 may display the icon related
to the first application in a right portion of the second area in
contact with the first area.
[0153] The controller 1202 may display the icon related to the
first application in response to the first area being moved. When
the first area of the first side is moved to the second side, the
controller 1202 may display the icon related to the first
application in an area corresponding to a moving direction of the
first area in the second area of the first side. For example, when
the first area is wound on a right side of the mobile terminal 1200
and located at the second side, the controller 1202 may display the
icon related to the first application in a right portion of the
second area.
[0154] In some cases, content of the second application may be
displayed in the second area in which the icon is displayed. Here,
the content of the second application may include content displayed
on the first side along with the content of the first application
but is not limited thereto. When the content of the second
application is displayed in the second area, the icon related to
the first application may be displayed to overlap the content of
the second application.
[0155] The controller 1202 may display the icon related to the
first application at a predetermined position on the display 1201
of the first side. For example, the controller 1202 may display the
icon related to the first application at a first position in an
upper portion of the first side.
[0156] When at least a portion of the first area is located at
another side, the controller 1202 may suspend displaying at least a
portion of content for a predetermined period of time or display a
separate layer to overlap at least a portion of the content for the
predetermined period of time. In this case, the icon related to the
first application may be displayed for the predetermined period of
time. After the predetermined period of time elapses, the
controller 1202 may terminate the first application providing the
content.
[0157] When at least a portion of the first area is located at
another side, the controller 1202 may control a brightness of at
least a portion of the first area located at the other side to a
predetermined value. For example, in response to at least a portion
of the first area being located at another side, first content (or
at least a portion of the first content) may be displayed in an
area located at the other side. In this example, the controller
1202 may control a brightness of the area in which the first
content is displayed on the other side, to the predetermined value.
The predetermined value may be a value previously determined for
providing a relatively dark screen.
[0158] In some cases, when at least a portion of the first area is
located at another side, the controller 1202 may display a separate
layer to overlap the first content or control the brightness of the
first area in which the first content is displayed to the
predetermined value.
[0159] The predetermined period of time may be determined based on
a type of the content of the first application displayed in the
first area. For example, when a type of the content is image or
video content, the predetermined period of time may be determined
to be a first time. Also, when a type of the content is a text, the
predetermined period of time may be determined to be a second time.
Here, the first time may be a time longer than the second time but
is not limited thereto.
[0160] The controller 1202 may display at least one of at least a
portion of content, information on the content, and information on
the predetermined period of time on the display 1201 located at the
first side. Specifically, the controller 1202 may further display
at least one of the at least the portion of content, the
information on the content, and the information on the
predetermined period of time in response to an icon indicating the
first application being displayed.
[0161] In such cases, at least a portion of the content may be
displayed in a size less than an original size and displayed when a
type of the content is related to an image or video. An example
related to at least a portion of content will be described in
detail with reference to FIG. 20. The information on the content
may include, for example, information on a type, a name, and a size
of the content or a name of the first application. The information
on the predetermined period of time may include, for example,
information on an amount of time that elapses from a point in time
at which the first area is located at the other side, the
predetermined period of time, or a remaining time calculated based
on a difference between the predetermined period of time and the
amount of time. An example of information on a predetermined period
of time will be described in detail with reference to FIG. 22 or
23.
[0162] When an input related to the first application is received,
the controller 1202 may display the content of the first
application in an area corresponding to the input. Specifically,
when the first input is received, the controller 1202 may display
the content of the first application in an area corresponding to
the first input. Also, when the second input is received, the
controller 1202 may display the content of the first application in
an area corresponding to the second input.
[0163] As an example, in response to the first input, the
controller 1202 may display the content of the first application in
the second area on the first side. The first input may include, for
example, an input applied to the icon related to the first
application displayed in the second area within a predetermined
period of time or a swipe input applied in a first direction to at
least a portion of the first side within the predetermined period
of time. In some cases, before the first input is received, the
content of the second application may be displayed in the second
area. In such cases, in response to the first input being received,
the content of the second application may be replaced with the
content of the first application. Here, the first input may be an
applied input.
[0164] As another example, in response to the second input, the
controller 1202 may display the content of the first application in
the first area located at the second side (or the display located
at the second side). The second input may include, for example, an
input applied to the first area on the second side within a
predetermined period of time or a swipe input applied in a second
direction to at least a portion of the first side within the
predetermined period of time.
[0165] In this example, the controller 1202 may deactivate touch
input sensing for the display 1201 located at the first side or
switch a screen of the display 1201 on the first side to a locked
state. When the second input is received, the controller 1202 may
display the content of the first application in the first area
located at the second side, and deactivate the touch input sensing
for the display 1201 located at the first side or switch the screen
of the display 1201 on the first side to the locked state.
[0166] As still another example, the controller 1202 may display
the content of the first application in at least a portion of the
first area in response to an expansion input for the display 1201
being applied within a predetermined period of time. Specifically,
when the controller 1202 identifies the expansion input for the
display 1201 applied within the predetermined period of time, the
controller 1202 may relocate at least a portion of the first area
from another side to the first side and display the content of the
first application in the at least the portion of the first area
located at the first side.
[0167] The controller 1202 may verify whether the at least the
portion of the first area located at the other side is relocated to
the first side within a predetermined period of time. When the at
least the portion of the first area located at the other side is
relocated to the first side within the predetermined period of
time, the controller 1202 may display the content of the first
application in the at least the portion of the first area located
at the first side.
[0168] In some cases, the at least the portion of the first area
located at the other side may be relocated to the first side after
the predetermined period of time elapses. In such cases, the
controller 1202 may display, in the first area, the content that is
displayed on the first side (or in the second area of the first
side). The content displayed in the first area may include content
different from the previously displayed content of the first
application. For example, when the at least the portion of the
first area located at the other side is relocated to the first side
after the predetermined period of time elapses, the content
displayed in the second area may be extended so as to be also
displayed in the first area located at the first side. However,
embodiments are not limited to the example. Another content may be
displayed in the first area relocated to the first side.
[0169] The controller 1202 may determine an area corresponding to
an input related to the first application based on a position at
which the first input is received. For example, when an input is
received at the first position, the controller 1202 may determine a
predetermined area including the first position to be an area
corresponding to the input. A related example will be further
described with reference to FIG. 16.
[0170] FIG. 13 is a flowchart illustrating operations of a method
of controlling a mobile terminal according to an example embodiment
of the present disclosure. Operations illustrated in FIG. 13 may be
performed in different orders or irrespective of an order depending
on cases. Hereinafter, redundant description which has been made
above will be omitted.
[0171] Referring to FIG. 13, in operation 1301, a mobile terminal
may display content of a first application in a first area of a
display located at a first side. Specifically, the mobile terminal
may display the content of the first application in the first area
of the display located at the first side based on an execution of
the first application. In some cases, based on the execution of the
first application and the second application, the mobile terminal
may display the first application in the first area of the display
located at the first side and display a second application in a
second area of the display.
[0172] In operation 1302, the mobile terminal may arrange at least
a portion of the first area of the display on another side.
Specifically, the mobile terminal may arrange at least a portion of
the first area of the display on another side based on an operation
of reducing a size of the display located at the first side. Here,
the first area of the display may include an area neighboring one
side of the mobile terminal, the one side being an axis (or
origination) of expansion or retraction of the display. In response
to the size reduction of the display, at least a portion of the
first area may be located to another side. For example, in response
to the size reduction of the display, the display may be wound on a
third side of the mobile terminal and then located to the second
side. In this example, the first area may include an area more
adjacent to the third side when compared to the second area.
[0173] When at least a portion of the first area of the display is
located at the other side, the mobile terminal may suspend
displaying content corresponding to the first area for a
predetermined period of time or display a separate layer to overlap
the content corresponding to the first area. The separate layer may
include, for example, another content displayed to overlap the
content with a predetermined transparency to indicate that
displaying of the content is suspended or another content displayed
in response to an inactivation of the first area. The predetermined
period of time may be differently set based on a type of content
displayed in the first area or a corresponding application. For
example, when the content displayed in the first area is video
content, the predetermined period of time may be about 15 seconds.
Also, when the content displayed in the first area is text content,
the predetermined period of time may be about ten seconds.
[0174] In response to the at least the portion of the first area
being located at the other side, the mobile terminal may display an
icon related to the first application on the display of the first
side. When the second area is located at the display of the first
side in response to response to the at least the portion of the
first area being located at the other side, the mobile terminal may
display the icon related to the first application in the second
area.
[0175] In operation 1303, when the first input related to the first
application is received, the mobile terminal may display the
content of the first application in an area corresponding to the
first input. As an example, when the first input related to the
first application is received, the mobile terminal may display the
content of the first application in at least a portion of the
second area. As another example, when the mobile terminal receives
the first input within a predetermined period of time from a point
in time at which calculation is started based on at least a portion
of the first area being located at another side (or content
displaying being suspended or the separate layer being displayed to
overlap the content), the mobile terminal may display the content
of the first application in the area corresponding to the first
input. Here, the point in time for starting calculation of the
predetermined period of time may be determined in advance.
[0176] An icon related to the first application may be displayed
for a predetermined period of time. When a touch input to the icon
is received within the predetermined period of time, the mobile
terminal may display the content of the first application in the
second area located at the first side. When the input to the icon
is not received within the predetermined period of time, the mobile
terminal may terminate the first application. An example of the
touch input to the icon will be described with reference to FIG.
16.
[0177] The mobile terminal may receive an input applied to a
predetermined position of the first side within a predetermined
period of time. In this case, the mobile terminal may display the
content of the first application in the second area located at the
first side. When the input applied to the predetermined position is
not received within the predetermined period of time, the mobile
terminal may terminate the first application. An example of the
input applied to the predetermined position will be described with
reference to FIG. 14.
[0178] FIG. 14 illustrates an example of an input to a mobile
terminal according to an example embodiment of the present
disclosure.
[0179] Referring to FIG. 14, a first screen 1401 may be displayed
on a display located at a first side of a mobile terminal. Also, a
second screen 1402 may be displayed on the display located at a
second side. Specifically, based on at least a portion of a first
area being located at the second side, the first screen 1401 may be
displayed on the first side and the second screen 1402 may be
displayed in the first area located at the second side.
[0180] In this case, a separate layer may be displayed to overlap
content previously displayed in the first area. However,
embodiments are not limited thereto. In some cases, content
displaying may be suspended or an input to the second side may be
restricted.
[0181] The separate layer may be continually displayed for a
predetermined period of time. Whether to display the content again
or terminate an application providing the content may be determined
based on an input applied within the predetermined period of time.
When a touch input 1410 to a predetermined position on the first
side is received within the predetermined period of time as
illustrated in FIG. 14, the content may be displayed again. The
content may be displayed in an area corresponding to the input. As
an example, content B associated with a second application may be
displayed in an area on the first side, for example, the first
screen 1401 on which content A associated with the second
application is displayed. An example of displaying the content B
will be further described with reference to FIG. 15.
[0182] Although FIG. 14 illustrates that the touch input 1410 is a
swipe input sliding in a first direction as an example, the present
example is not to be taken as being limited thereto. The touch
input 1410 may be implemented as various types of input, for
example, an input including at least one of a touch input to a
predetermined position, a long-press input, and a knock-on
input.
[0183] Predetermined content, for example, a text may be displayed
on the separate layer displayed on the second screen 1402. The text
may include, for example, a text indicating a locked screen or a
text indicating information for releasing the locked screen. For
example, the text may include a text "back screen is locked" or a
text "slide screen to the right to use back screen."
[0184] When a predetermined input is applied to the second screen
1402, the mobile terminal may provide the content B on the second
screen, terminate displaying the separate layer, or unlock the
second screen. The predetermined input may be an input designated
in advance and may include, for example, a swipe input in a
predetermined direction.
[0185] FIG. 15 illustrates an example of a screen displayed on a
mobile terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 15 illustrates a case in which
content having been provided in a first area is displayed on a
screen located at a first side in response to an input being
received within a predetermined period of time after at least a
portion of the first area is located at the second side.
[0186] Referring to FIG. 15, when an input is received within a
predetermined period of time after at least a portion of the first
area is located at the second side, a first screen 1501 may be
displayed on a display of the first side and a second screen 1502
may be displayed on a display of the second side. Specifically, in
response to a first input (e.g., an input to a predetermined
position on the first side and a touch input to an icon displayed
on the first side) being received within the predetermined period
of time, content B 1510 of a first application may be displayed on
the first screen 1501 located at the first side.
[0187] As illustrated, content A of a second application may be
displayed on the first side. In this case, in response to the first
input, the content B may be displayed to overlap the content A as
shown in the first screen 1501. Here, the content B may correspond
to content of the first application displayed in the first area
before at least a portion of the first area is located at the
second side but is not limited thereto. Instead, at least a portion
of the content of the first application or another content of the
first application may be displayed.
[0188] Although not shown, in some cases, the content B may be
displayed on the entire of the first screen 1501 to replace the
content A in response to the input.
[0189] The second screen 1502 may correspond to an empty screen on
which provision of content is suspended. However, it is merely an
example and the second screen 1502 may include, for example, a
locked screen or an always-on-display (AOD) screen. Although not
shown, when the second screen 1502 includes an AOD screen,
predetermined information, for example, time or alarm information
may be displayed on the second screen 1502.
[0190] FIG. 16 illustrates an example of displaying content on a
mobile terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 16 illustrates a mobile terminal in
a case in which three contents are displayed based on an execution
of three applications.
[0191] Referring to FIG. 16, based on three applications being
executed, a first screen 1601 including content A associated with a
first application, content B associated with a second application,
and content C associated with a third application may be displayed
on a display of a first side. As illustrated in FIG. 16, the
content C may be displayed in a first area, and the content A and
the content B may be respectively displayed in an upper portion and
a lower portion of a second area.
[0192] In response to a size reduction of the display, at least a
portion of the first area may move from the first side to be
located at another side of the mobile terminal. In this case, a
second screen 1602 may be displayed on the first side of the
display and a third screen 1603 may be displayed on the other side.
For example, when the first area is located at the second side in
response to the size reduction of the display, the second screen
1602 including the content A and the content B may be displayed on
the first side and the third screen 1603 in which displaying of the
content C is suspended or a separate layer overlaps the content C
may be displayed on the other side. Here, the other side may
include the second side but is not limited thereto. The other side
may also include a third side located between the first side and
the second side.
[0193] As shown in the second screen 1602 of FIG. 16, in response
to at least a portion of the first area being located at the other
side, an icon 1610 related to an application corresponding to the
first area may be displayed on the first side. For example, the
icon 1610 may include an icon indicating an application providing
content displayed in at least a portion of the first area located
at the other side.
[0194] The icon 1610 may be displayed fora predetermined period of
time. Here, the predetermined period of time may be a predetermined
period of time (e.g., ten seconds) and calculated from a point in
time at which at least a portion of the first area is located at
the other side. However, the point in time for starting calculation
of the predetermined period of time is not limited thereto. For
example, the predetermined period of time may be calculated from a
point in time at which content displaying is suspended or a point
in time at which a separate layer is superimposed on content.
[0195] The icon 1610 may further include information on the
predetermined period of time in addition to the icon indicating the
application. For example, as illustrated, an image representing a
percentage of elapsed time in the predetermined period of time may
be displayed on a perimeter of the icon. However, it is merely an
example and the information on the predetermined period of time may
be displayed along with the icon in various ways. A related example
will be described in detail with reference to FIG. 22 or 23.
[0196] The icon 1610 may be implemented as a floating icon to move
based on an input of a user. Specifically, the icon 1610 may be
moved in response to a drag input to the icon 1610. For example, as
shown in a fourth screen 1604, the icon 1610 displayed to overlap a
portion of the content A in the second screen 1602 may be moved to
an area in which the content B is displayed. In this example, a
fifth screen 1605 may be displayed on the second side. The fifth
screen 1605 may correspond to the third screen 1603.
[0197] When an input to the icon 1610 is applied within a
predetermined period of time, the mobile terminal may display
content corresponding to the icon 1610 in an area corresponding to
the input. For example, when the icon 1610 is related to the third
application providing the content C in the first area located at
the second side, the mobile terminal may display the content C in
response to an input to the icon 1610 being received.
[0198] When a screen displayed on the first side includes a
plurality of contents as shown in the fourth screen 1604, a
position for displaying the content C may be determined based on an
input (or a position of the icon 1610). As an example, when an
input for the icon 1610 is applied to one area overlapping the
content B based on the icon 1610 displayed to overlap the content B
as shown in the fourth screen 1604, the content C corresponding to
the icon 1610 may be displayed in at least a portion of an area in
which the content B is displayed as shown in a sixth screen
1606.
[0199] As another example, when a first input is applied based on
the icon 1610 displayed to overlap the content B as shown in the
fourth screen 1604, the content C corresponding to the icon 1610
may be displayed in at least a portion of the area in which the
content B is displayed as shown in the sixth screen 1606. In this
example, the second application providing the content B may be
terminated. Here, the first input may include an input applied to
the icon 1610 but not is limited thereto. For example, the first
input may include an input to a predetermined position on the first
side or a predetermined type of input (e.g., a swipe input).
[0200] When the sixth screen 1606 is displayed through the display
of the first side, a seventh screen 1607 may be displayed on the
display of the second side. When the third screen 1603 or the fifth
screen 1605 is a screen in which a separate layer overlaps the
content C, the seventh screen 1607 may be a screen in which
displaying of the content C and the separate layer is
terminated.
[0201] FIG. 17 illustrates another example of displaying content on
a mobile terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 17 illustrates a case in which an
area located at a second side includes a plurality of contents to
correspond to a size reduction of a display or an input for
displaying content is received on the second side.
[0202] Referring to FIG. 17, contents (content A, content B,
content C, and content D) of different applications may be
displayed on a display of a first side. In this instance, in
response to a size reduction of the display, a first screen 1701
may be displayed on the display located at the first side and a
second screen 1702 may be displayed on the display located at a
second side. As illustrated, the first screen 1701 may include the
content A of a first application and the content B of a second
application. Also, the second screen 1702 may include the content C
of a third application and the content D of a fourth application.
In the second screen 1702, a separate layer may be displayed to
overlap the content C and the content D.
[0203] The mobile terminal may display an icon of an application
related to an area located at the second side as shown in the first
screen 1701 in response to the size reduction of the display. When
a plurality of applications are related to the area located at the
second side, icons (e.g., a first icon 1710 and a second icon 1720)
respectively indicating the applications may be displayed as
illustrated in FIG. 17.
[0204] When the plurality of applications is related to the area
located at the second side, the icons may be displayed based on
positions of contents related to the applications. For example,
when the content C and the content D are vertically arranged in the
area located at the second side, the first icon 1710 corresponding
to the content C and the second icon 1720 corresponding to the
content D may also be arranged vertically.
[0205] The mobile terminal may display contents corresponding to
the icons (e.g., the first icon 1710 and the second icon 1720)
based on inputs applied to the icons. Specifically, the mobile
terminal may receive the inputs applied to the icons within a
predetermined period of time and display the contents based on the
received inputs and the icons to which the inputs are applied. For
example, as illustrated, when a right-direction swipe input applied
to the first icon 1710 is received, the content C corresponding to
the first icon 1710 may be displayed on the second side. Through
this, a fourth screen 1704 may be displayed on the second side and
a third screen 1703 may be displayed on the first side. Here, the
right-direction swipe input may be an input for displaying content
on the second side and correspond to the second input described
with reference to FIG. 12.
[0206] Although not shown, when a left-direction swipe input to the
first icon 1710 is received, the content C corresponding to the
first icon 1710 may be displayed in at least a portion (e.g., an
area corresponding to the content A) of the first side. In this
case, the application providing the content D may be terminated and
a screen of the second side may be changed to a locked screen, an
empty screen, or an AOD screen. Here, the left-direction swipe
input may be an input for displaying content on the first side and
correspond to the first input described with reference to FIG.
12.
[0207] The third screen 1703 may include a screen in which
displaying of the first icon 1710 and the second icon 1720 is
terminated based on an input to the first icon 1710. For example,
the third screen 1703 may include, but not be limited to, content
1730 indicating a state of the second side as illustrated. The
third screen 1703 may include other contents or may not display the
content 1730.
[0208] On the fourth screen 1704, the content C corresponding to
the first icon 1710 may be displayed based on the input to the
first icon 1710. The fourth screen 1704 may include a screen in
which displaying of the content D corresponding to the second icon
1720 is terminated. In this case, the application providing the
content D may be terminated.
[0209] When the predetermined period of time elapses without
receiving the input to the first icon 1710 or the second icon 1720,
displaying of the first icon 1710 and the second icon 1720, the
application corresponding to the first icon 1710, and the
application corresponding to the second icon 1720 may be
terminated. In this case, the display of the second side may
display an empty screen or an AOD-state screen.
[0210] Referring to FIG. 17, when a plurality of contents is
displayed vertically, a button for discriminating the contents and
adjusting a size of each of the contents may be displayed. The
button may be vertically moved such that the vertically arranged
contents, for example, the content A and the content B, and the
content C, and the content D, are adjusted in size in response to
the movement of the button.
[0211] FIGS. 18 and 19 illustrate examples of displaying an icon on
a mobile terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 18 illustrates an example of
displaying an icon in a case in which different contents are
displayed horizontally in an area located at a second side and FIG.
19 illustrates an example of displaying an icon in a case in which
different contents are displayed vertically in the area located at
the second side.
[0212] Referring to FIG. 18, in a display-extended state, a first
screen 1801 in which content A, content B, and content C are
arranged in parallel may be displayed on a first side. In response
to a size reduction of a display, an area in which the content C is
displayed and an area in which the content B is displayed may
sequentially move to a second side and arranged on the second side.
In this case, an icon corresponding to the content C and an icon
corresponding to the content B may be sequentially displayed.
[0213] Specifically, in response to the area in which the content C
is displayed being located at the second side, a second screen 1802
may be displayed on the first side and a third screen 1803 may be
displayed on the second side. The second screen 1802 may include a
first icon 1810 for the content C. The first icon 1810 may be
displayed in response to the area in which the content C is
displayed being located at the second side. The third screen 1803
may include a screen in which a separate layer overlaps the content
C but is not limited thereto. The third screen 1803 may also
include a screen in which displaying of the content C is suspended,
a locked screen, an empty screen, or an AOD screen.
[0214] In response to the area in which the content B is displayed
being located at the second side, a fourth screen 1804 may be
displayed on the first side and a fifth screen 1805 may be
displayed on the second side. The fourth screen 1804 may include a
second icon 1820 for the content B in addition to the first icon
1810. The second icon 1820 may be displayed in response to the area
in which the content B is displayed being located at the second
side. The fifth screen 1805 may include a screen in which a
separate layer overlaps the content B and the content C but is not
limited thereto. The fifth screen 1805 may also include a screen in
which displaying of the content B and the content C is suspended, a
locked screen, an empty screen, or an AOD screen.
[0215] As illustrated in FIG. 18, on a perimeter of each of the
first icon 1810 and the second icon 1820, information on a
predetermined period of time calculated in response to a relocation
to the second side may be displayed in an area corresponding to the
content related to each of the icons. The information on the
predetermined period of time may include, for example, an image
representing an amount of time (e.g., three seconds) that elapses
from a point in time at which the area related to each of the icons
is located at the second side in the predetermined period of time
(e.g., ten seconds). When the predetermined period of time elapses
without receiving an input to the icon, displaying of the icon and
an application corresponding to the icon may be terminated. For
example, when an input to the first icon 1810 is not received until
the predetermined period of time elapses since the first icon 1810
is displayed, an application providing content related to the first
icon 1810, that is, the content C displayed on the second side may
be terminated. Accordingly, the content C may not be displayed on
the second side. When the first icon 1810 and the second icon 1820
have different points in time for starting calculation of the
predetermined period of time, applications related to the first
icon 1810 and the second icon 1820 may be terminated at different
points in time.
[0216] Referring to FIG. 18, the first icon 1810 and the second
icon 1820 may be arranged in parallel in response to the contents
corresponding to the first icon 1810 and the second icon 1820 being
arranged in parallel.
[0217] Referring to FIG. 19, content A, content B, and content C
may be displayed on a first screen 1901 in a display-extended
state. The content B and the content C may be arranged vertically.
In this case, in response to a size reduction of a display, at
least a portion of the content B and at least a portion of the
content C may be arranged at a second side together.
[0218] In response to at least a portion of the content B and at
least a portion of the content C being arranged at the second side
together, a first icon 1910 corresponding to the content B and a
second icon 1920 corresponding to the content C may be displayed
together. For example, a second screen 1902 including the first
icon 1910 and the second icon 1920 may be displayed on a first
side.
[0219] In response to the second screen 1902 being displayed, a
third screen 1903 may be displayed on the second side. The third
screen 1903 may include a screen in which a separate layer overlaps
the content B and the content C but is not limited thereto. The
third screen 1903 may also include a screen in which displaying of
the content B and the content C is suspended, a locked screen, an
empty screen, or an AOD screen, for example.
[0220] As illustrated, information on a predetermined period of
time may be displayed on perimeters of the first icon 1910 and the
second icon 1920. In the example of FIG. 19, since each icon has
the same point in time for starting calculation of the
predetermined period of time, the same information may be displayed
on the perimeters. If an input to at least one of the first icon
1910 and the second icon 1920 is not received within the
predetermined period of time, displaying of the first icon 1910 and
the second icon 1920 may be terminated and applications related to
the icons may also be terminated.
[0221] When an input to the first icon 1910 or the second icon 1920
is received within the predetermined period of time, content
corresponding to an icon to which the input is applied may be
displayed in an area corresponding to the received input. In this
case, displaying of other icons to which an input is not applied
and applications related to the other icons may be terminated.
However, it is merely an example, and the other icons may be
continually displayed until the predetermined period of time
elapses depending on a case.
[0222] FIGS. 20 and 21 illustrate screens displayed on a mobile
terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 20 illustrates a mobile terminal
that displays an icon in response to predetermined content being
arranged on a second side and controls displaying of the
predetermined content based on an input applied to the icon. FIG.
21 illustrates a mobile terminal that controls displaying of
predetermined content based on an input applied after the
predetermined content is arranged on a second side.
[0223] Reference numerals 20a, 20b, and 20c of FIG. 20 show a first
side (e.g., a front side) of the mobile terminal. Reference numeral
20d of FIG. 20 shows a second side (e.g., another side) of the
mobile terminal. As indicated by the reference numeral 20a, based
on a plurality of applications being executed, content for each of
the plurality of the applications may be displayed on the first
side. Specifically, on the first side, first content 2011
associated with a first application, second content 2012 associated
with a second application, third content 2013 associated with a
third application, and fourth content 2014 associated with a fourth
application may be displayed.
[0224] Based on a size reduction of a display, a first area
including the second content 2012 and the fourth content 2014 may
be located to another side (e.g., the second side) of the mobile
terminal. In this case, as indicated by the reference numeral 20b,
a second area including the first content 2011 and the third
content 2013 may remain and be displayed on the first side. Also,
an icon 2021 for content (e.g., the second content 2012) having
been displayed in the first area may be displayed on at least a
portion of the first side.
[0225] Although the reference numeral 20b shows the first side on
which the icon 2021 is displayed to overlap another content (e.g.,
the first content 2011) as an example, the present example is not
to be taken as being limited thereto. For example, the icon 2021
may be displayed in a separate area. In response to the second
content 2012 being arranged on another side, calculation of a
predetermined period of time may be started. The predetermined
period of time may be a period of time in which displaying of the
icon 2021 and the second application are maintained. In this case,
information on the predetermined period of time may be displayed.
The information on the predetermined period of time may be
displayed on a perimeter of the icon 2021 as illustrated but is not
limited thereto.
[0226] In response to content being arranged on the other side, at
least a portion of the content arranged on the other side or
information on the content may be displayed. As indicated by the
reference numeral 20b, in response to the fourth content 2014 being
arranged on the other side, at least a portion of the fourth
content 2014, for example, fifth content 2022 may be displayed on
the first side.
[0227] In some cases, when content arranged on the other side
includes a predetermined type of content, the mobile terminal may
display at least a portion of the content arranged on the other
side, on the first side. The predetermined type may include, but is
not limited to, an appreciation type such as a video or image, or a
type that requires at least a predetermined period of time for
loading content, for example. When the predetermined type includes
the appreciation type, at least a portion of content may include a
portion corresponding to an image or video included in the
content.
[0228] Like the aforementioned icons, the fifth content 2022 may be
displayed for a predetermined period of time from a point in time
at which the fourth content 2014 is arranged on the other side. In
some cases, as illustrated, information on the predetermined period
of time may be displayed on a perimeter of the fifth content
2022.
[0229] The predetermined period of time may vary based on a type of
content. For example, when content is a first type, the
predetermined period of time may be a first time. Also, when
content is a second type, the predetermined period of time may be a
second time. In some cases, the first time may be longer than the
second time. In such cases, the first type may include a content
type that requires at least the predetermined period of time for
loading, for example, streaming content such as a video.
[0230] The mobile terminal may receive an input to at least one of
the icon 2021 and the fifth content 2022. When an input to the icon
2021 is received, the mobile terminal may display content
corresponding to the icon 2021, for example, the second content
2012 in an area corresponding to the input. As an example, the
mobile terminal may receive a first input to the fifth content
2022. In this example, as indicated by the reference numeral 20c,
content corresponding to the fifth content 2022, for example, the
fourth content 2014 may be displayed in an area corresponding to
the first input.
[0231] As another example, when a second input (e.g., an input of
swiping the icon 2021 to the right) to the icon 2021 is received,
the mobile terminal may display content corresponding to the icon
2021, for example, the second content 2012 on the second side as
indicated by the reference numeral 20d. Although not shown, when
the first input (e.g., an input of swiping the icon 2021 to the
left or a touch input to the icon 2021) to the icon 2021 is
received, the mobile terminal may display content corresponding to
the icon 2021, for example, the second content 2012 on the first
side.
[0232] Reference numeral 21a of FIG. 21 may correspond to the
reference numeral 20a of FIG. 20. Likewise, first content 2111 of
FIG. 21 may correspond to the first content 2011 of FIG. 20, second
content 2112 of FIG. 21 may correspond to the second content 2012
of FIG. 20, third content 2113 of FIG. 21 may correspond to the
third content 2013 of FIG. 20, and fourth content 2114 of FIG. 21
may correspond to the fourth content 2014 of FIG. 20.
[0233] Based on a size reduction of a display, a first area
including the second content 2012 and the fourth content 2014 may
be located at another side of a mobile terminal (e.g., the second
side). In this case, content (or an application associated with the
content) corresponding to an area located at the other side may be
held on for a predetermined period of time.
[0234] For example, when an area including the second content 2112
is located to another side, an execution of an application
providing the second content 2112 may be suspended. In this
example, when a first input 2121 is applied within a predetermined
period of time as indicated by reference numeral 21b, the
suspension of the execution of the application may be canceled so
that the second content 2112 is displayed again in an area
corresponding to the input (for example, an area in which the first
content 2111 is displayed on the first side) as indicated by
reference numeral 21c. If the predetermined period of time elapses
without receiving an input, the application providing the second
content 2112 may be terminated.
[0235] As indicated by reference numeral 21c, when the second
content 2112 is displayed on the first side in response to the
first input 2121, the first content 2111 may be obscured by the
second content 2112. In this case, as indicated by reference
numeral 21d, the first content 2111 may be displayed again on the
first side based on a switch input 2122. When the first input 2121
has a predetermined direction, the switch input 2122 may include an
input of a direction opposite to that of the first input 2121.
However, it is merely an example and the switch input 2122 may
include a predetermined input.
[0236] When content arranged at another side includes a plurality
of contents, the mobile terminal may display at least one of the
arranged contents in an area corresponding to the first input 2121
based on the first input 2121 and a position to which the first
input 2121 is applied. For example, when the first input 2121 is
applied to a portion of the area in which the first content 2111 is
displayed as indicated by the reference numeral 21b, the second
content 2112 may be displayed in an area corresponding to an area
to which the first input 2121 is applied (e.g., the area in which
the first content 2111 is displayed) as indicated by the reference
numeral 21c. Although not shown, when the first input 2121 is
applied to a portion of an area in which the third content 2113 is
displayed, the second content 2112 may be displayed in the area in
which the third content 2113 is displayed.
[0237] Although FIG. 21 illustrates a case in which the first input
2121 is implemented as a swipe input of a left direction, it is
merely provided as an example and the first input 2121 may be
implemented as various types of inputs.
[0238] FIGS. 22 and 23 illustrate examples of icons displayed on a
mobile terminal according to an example embodiment of the present
disclosure. Specifically, FIG. 22 illustrates an example of
displaying an icon in association with information on a
predetermined period of time. FIG. 23 illustrates an example of
displaying an icon separate from information on a predetermined
period of time.
[0239] Referring to FIG. 22, when an area for displaying first
content is located at a second side and calculation of a
predetermined period of time starts, an icon related to an
application providing the first content may be displayed on a first
side as a (1-1).sup.th state 2201, a (2-1).sup.th state 2211, or a
(3-1).sup.th state 2221. In other words, at a point in time for
starting the calculation of the predetermined period of time, the
information on the predetermined period of time may be represented
as the (1-1).sup.th state 2201, the (2-1).sup.th state 2211, or the
(3-1).sup.th state 2221 in association with the icon.
[0240] When the information on the predetermined period of time is
displayed as the (1-1).sup.th state 2201, the (1-1).sup.th state
2201 may sequentially change to a (1-2).sup.th state 2202 and a
(1-3).sup.th state 2203 by lapse of time. The (1-1).sup.th state
2201 represents an icon around which a bar is provided. The bar may
gradually disappear over time. When the predetermined period of
time elapses, only the icon may remain without displaying the
bar.
[0241] When the information on the predetermined period of time is
displayed as the (2-1).sup.th state 2211, the (2-1).sup.th state
2211 may sequentially change to a (2-2).sup.th state 2212 and a
(2-3).sup.th state 2213 by lapse of time. The (2-1).sup.th state
2211 may correspond to a basic icon of an application. A color of
the icon may gradually change to another color over time. For
example, if the (2-2).sup.th state 2212 corresponds to a point in
time at which a quarter of the predetermined period of time has
elapsed, the (2-2).sup.th state 2212 may be a state in which about
a quarter of the icon is changed in color.
[0242] When the information on the predetermined period of time is
displayed as a (3-1).sup.th state 2223, the (3-1).sup.th state 2223
may sequentially change to a (3-2).sup.th state 2222 and a
(3-3).sup.th state 2223 by lapse of time. The (3-1).sup.th state
2221 may correspond to a basic icon of an application. A brightness
or shade of the icon may gradually change over time. As the
predetermined period of time elapses, for example, as a state of
the icon changes from the (3-1).sup.th state 2221 to the
(3-2).sup.th state 2222 and the (3-3).sup.th state 2223, the
brightness of the icon may decrease or the shade of the icon may
increase.
[0243] Referring to FIG. 23, in response to a size reduction of a
display, a first screen 2301 or a third screen 2303 may be
displayed on a first side. A second screen 2302 may be, for
example, a screen displayed on a display located at a second side
in response to the first screen 2301 being displayed. A fourth
screen 2304 may be, for example, a screen displayed on the display
located at the second side in response to the third screen 2303
being displayed.
[0244] In response to the size reduction of the display, at least a
portion of an area in which content of a first application is
displayed may be located at the second side. In this case,
displaying of the content of the first application may be suspended
for a predetermined period of time or a separate layer may be
displayed on the content of the first application for the
predetermined period of time. Also, as illustrated in FIG. 23,
information 2310 and 2320 on the predetermined period of time may
be displayed on the display of the first side, for example, the
first screen 2301 or the third screen 2303.
[0245] In one example, as shown in the first screen 2301, the
information 2310 on the predetermined period of time may be
displayed at a position corresponding to a direction in which the
display is previously located or a position at which the display is
wound due to the size reduction of the display. In another example,
as shown in the third screen 2303, the information 2320 on the
predetermined period of time may be displayed at a predetermined
position such as an upper end of a screen. As such, the information
2310 and 2320 on the predetermined period of time may be
information indicating an elapsed time with respect to the
predetermined period of time. The information 2310 and 2320 may be
displayed as a bar image as illustrated in FIG. 23 but is not
limited thereto.
[0246] In the present disclosure, in a case in which content
displayed on a front side is moved to a rear side due to a size
reduction of a display, a mobile terminal and a control method of
the mobile terminal may hold the content in a standby state for a
predetermined period of time instead of immediately terminating the
content so as to quickly display content when a user is to use the
content again.
[0247] Further, in the present disclosure, a mobile terminal and a
control method of the mobile terminal may terminate content and an
application providing the content after a predetermined period of
time elapses, thereby achieving increased efficiency in driving the
mobile terminal.
[0248] Further, in the present disclosure, a mobile terminal and a
control method of the mobile terminal may determine a position for
displaying content based on an input received within a
predetermined period of time, thereby appropriately providing the
content for use pattern of a user.
[0249] According to example embodiments, it is possible to provide
a mobile terminal for providing content and a control method
thereof. The mobile terminal may display content of an application
in an area corresponding to a received input when a display of the
mobile terminal is changed in size, thereby reflecting user's needs
and achieving increased efficiency in providing content.
[0250] According to example embodiments, it is possible to quickly
display content in response to a request for re-displaying by
holding an application related to the content in a standby state
instead of terminating the application even if a content display
area is reduced based on a size change of a display.
[0251] Effects are not limited to the aforementioned effects, and
other effects not mentioned will be clearly understood by those
skilled in the art from the description of the claims.
[0252] The above description is merely illustrative of the
technical idea of the present disclosure, and those skilled in the
art to which the present disclosure pertains can make various
modifications and changes without departing from the essential
quality of the present disclosure. Accordingly, the embodiments
disclosed herein are not intended to limit the technical spirit of
the present disclosure but to describe the present disclosure, and
the scope of the technical spirit of the present disclosure is not
limited by these embodiments. The scope of protection of the
present disclosure should be interpreted by the following claims,
and all technical ideas that fall within the scope of equivalents
thereof should be construed as being included in the scope of the
present disclosure.
