TECHNICAL FIELD
[0002] The present disclosure relates to the field of display
screen, and particularly to a display screen assembly, a terminal
front cover, and a terminal.
BACKGROUND
[0003] The display screen assembly of a traditional mobile phone is
composed of a cover plate and a display screen. The cover plate is
laminated on the display screen. The inner surface of the cover
plate is generally divided into two parts, that is, an ink area and
a display region. The ink area is formed by applying an ink layer
on the inner surface of the cover plate. The ink layer is used to
shield the area at the edge of the display screen where images
cannot be displayed, while the display region is an area where the
cover plate can effectively display images of the display screen.
Generally, the ink area does not display any images on the exterior
surface of the cover plate, and therefore, the ratio of the display
region to the exterior surface of the cover plate cannot be
improved. It can be difficult to obtain a larger display screen and
is not ergonomic.

[0022] Implementations of the present disclosure will be described
in detail. In the following, the same reference numerals are used
to refer to the same or similar elements throughout the
specification.
[0023] A display screen assembly 100 according to an implementation
of the first aspect will be described with reference to FIG. 1 and
FIG. 2.
[0024] As illustrated in FIG. 1, the display screen assembly 100
according to the implementation of the first aspect includes a
display screen 10 (specifically, a display panel), a lighting
assembly such as a light guide plate 20 and/or additional
components thereof (a light source for example), the touch panel
30, and a cover plate 40. As another implementation, the lighting
assembly can also be an annular LED array.
[0025] As illustrated in FIG. 1 and FIG. 2, the display screen 10,
the light guide plate 20, the touch panel 30, and the cover plate
40 are sequentially stacked. The display screen 10 includes a
display surface 11. The display surface 11 has a display region 111
and a non-display region 112. The non-display region 112 surrounds
the display region 111. The light guide plate 20 is arranged on one
side (for example, the upper side of FIG. 1 and FIG. 2) of the
display screen 10 that is adjacent to the display surface 11. The
light guide plate 20 covers the non-display region 112. The outer
edge of the light guide plate 20 is provided with a light source
20a. The light source 20a is configured to illuminate the light
guide plate 20.
[0026] The display surface 11 is disposed on one side of the
display screen 10 that is adjacent to the light guide plate 20. The
display region 111 is an area of the display screen 10 that can
display image information effectively. The non-display region 112
is an area of the display screen 10 that cannot display the image
information effectively. Normally, the non-display region 112 is
used for circuit connection, or is provided with a backlight lamp,
or is used for packaging a liquid crystal layer of the display
screen 10. The display screen 10 can be one of a LCD (Liquid
Crystal Display) screen and a LCM (LCD Module) component. The
display screen 10 can also be a widely used touch screen. For
example, the display screen 10 can be an in-cell touch screen in
which a touch layer is embedded into liquid crystal pixels. The
display screen 10 can be an on-cell touch screen in which the touch
layer is arranged on the liquid crystal pixels. The display screen
10 can also be a full-fit touch screen in which the touch layer is
fully attached to the cover plate.
[0027] The touch panel 30 is disposed on one side (for example, the
upper side of FIG. 1 and FIG. 2) of the light guide plate 20 that
is remote from the display screen 10. The touch panel 30 covers the
light guide plate 20. The touch panel 30 is provided with at least
one virtual key (not illustrated in the figures). For ease of
explanation, in the following, take one virtual key as an example
for description.
[0028] The cover plate 40 is provided on one side of the touch
panel 30 that is remote from the light guide plate 20. The cover
plate 40 includes a light transmitting portion 41 (can be referred
to as a light transmission window) and a light shielding band 42
enclosing the periphery of the light transmitting portion 41 (that
is, surrounding the light transmitting portion 41). The light
emitted from the light source 20a are adapted to pass through the
light guide plate 20, a keypad region 421, and the light
transmitting portion 41.
[0029] The keypad region 421 is configured to be illuminated by the
light of the lighting assembly such as the light guide plate, more
specifically, the light source 20a. The light transmitting portion
41 passes through the light of the display region 111
correspondingly. The light shielding band 42 includes the keypad
region 421 and areas other than the keypad region 421. The areas
other than the keypad region 421 can be provided around the keypad
region 421 and can be referred to as a shielding region 422. The
keypad region 421 can be illuminated by the light of the light
guide plate 20 and pass through the light of the light guide plate
20. The keypad region 421 can be disposed corresponding to the
virtual key of the touch panel 30 (that is, the keypad region 421
corresponds to the virtual key). The shielding region 422 shields
the light of the light guide plate 20.
[0030] In the display screen assembly 100 according to the
implementation of the present disclosure, the light guide plate 20
is configured to cover the light guide plate 20 correspondingly,
and the light source 20a is configured to illuminate the light
guide plate 20. Besides, the light shielding band 42 is configured
to include the keypad region 421 and the shielding region 422
provided around the keypad region 421. The keypad region 421 is
configured to pass through the light of the light guide plate 20
and is arranged corresponding to the virtual key of the touch panel
30. The shielding region 422 is configured to shield the light of
the light guide plate 20, such that the non-display region 112 of
the display screen 10 can be utilized and the space of the display
screen assembly 100 used to arrange keys can be saved, and
therefore, the display region of the display screen assembly 100
can be enlarged effectively and this is ergonomic. It is to be
understood that the display screen assembly 100 is applicable to a
terminal device. The terminal device can be one of a mobile phone,
a notebook computer, a tablet computer, an electronic reader, an
electronic album, a display and the like.
[0031] The light guide plate 20 has a first surface and a second
surface which are disposed opposite to each other. The first
surface is adjacent to the display screen 10 and the second surface
is adjacent to the touch panel 30. The first surface and the second
surface can be formed as planes parallel to each other, or, the
second surface can be formed as an arc-shaped surface. For example,
as illustrated in FIG. 1, the light guide plate 20 is annular. The
light guide plate 20 includes a bottom surface 21 (i.e., the first
surface) and a top surface 22 (i.e., the second surface) which are
disposed opposite to each other. The light guide plate 20 further
includes an outer side surface 23 provided between the bottom
surface 21 and the top surface 22. The bottom surface 21 is
correspondingly attached to the non-display region 112 of the
display surface 11. The top surface 22 is attached to the touch
panel 30. The outer side surface 23 corresponds to the edge of the
display surface 11. The outer side surface 23 is configured to
receive the light of the light source 20a, whereby the light guide
plate 20 can be illuminated and the top surface 22 can emit light.
The light emitted by the top surface 22 can pass through the touch
panel 30 as well as the keypad region 421, thus making the keypad
region 421 visible. In this way, the keypad region 421 can identify
the virtual key of the touch panel 30, and the non-display region
112 of the display surface 11 can be utilized to receive touch
instructions. In this implementation, the top surface 22 is
parallel to the bottom surface 21, so that the thickness of the
light guide plate 20 can be reduced. In other implementations, the
top surface 22 may be an arc-shaped surface such that the light
emitting area of the top surface 22 is larger and the area of the
keypad region 421 can be increased.
[0032] In this implementation, the touch panel 30 can be integrated
into the cover plate 40, that is, the touch panel 30 is integrated
with the cover plate 40, and in other words, the touch panel 30 is
integrally formed with the cover plate 40. The touch panel 30
covers the light guide plate 20 correspondingly and covers the
display region 111 of the display screen 10, such that the touch
panel 30 corresponding to the non-display region 112 or the display
region 111 can realize the input of touch instructions. Multiple
virtual keys can be provided. The multiple virtual keys can
implement input of multiple different key instructions. In other
implementations, the touch panel 30 is annular; the touch panel 30
correspondingly covers the light guide plate 20.
[0033] In this implementation, the cover plate 40 is made of glass.
The cross-section of the cover plate 40 is parallel to the display
surface 11 of the display screen 10. The cover plate 40 is a
rectangular plate member. The cover plate 40 includes an outer
surface 40a and an inner surface 40b which are disposed opposite to
each other. The outer surface 40a faces the user and is the
exterior surface of the cover plate 40. The inner surface 40b
deviates from the user. The inner surface 40b covers the light
guide plate 20 and the display region 111 correspondingly. The
light transmitting portion 41 of the cover plate 40 can enhance the
light transmittance of the display screen 10 and can enhance the
visual effect of the display screen assembly 100. The light
shielding band 42 shields the light guide plate 20; that is, the
light shielding band 42 covers the non-display region 112 of the
display screen 10, thereby preventing (or limiting) the non-display
region 112 from affecting the visual effect. The cover plate 40
further includes an outer side wall 43 secured between the outer
surface 40a and the inner surface 40b. The outer side wall 43 may
be fixed to the housing of the terminal device. The cover plate 40
is a transparent hard plate member. The cover plate 40 has a good
protective effect on the display screen 10 and can achieve good
light transmission.
[0034] Further, an ink layer 42a is provided between the cover
plate 40 and the touch panel 30. The ink layer 42a corresponds to
the shielding region 422 of the light shielding band 42. As
illustrated in FIG. 1 and FIG. 2, the cover plate 40 includes an
inner surface 40b close to the touch panel 30. The inner surface
40b is provided with the ink layer 42a corresponding to the
shielding region 422 of the light shielding band 42. As one
implementation, the ink layer 42a is printed on the inner surface
40b by a screen printing technique. By virtue of the opacity of the
ink layer 42a, covering of the non-display region 112 can be
achieved, and partial light of the light guide plate 20 is
prevented from passing through. Normally, the ink layer 42a is
black; the ink layer 42a causes the light shielding band 42 to be
black. In other situations, the ink layer 42a may also use white
ink.
[0035] Further, the keypad region 421 is provided with a key
pattern code(s) (not illustrated). The key pattern code is
configured to identify the virtual key. As one implementation, the
key pattern code is provided in a blank area of the ink layers 42a.
Multiple different key pattern codes may be provided for multiple
keypad regions 421, and each key pattern code can be configured to
represent a key with a different function. When the light guide
plate 20 is illuminated, the light of the light guide plate 20
passes through the key pattern code, such that the key pattern code
glows and the pattern identified by the key pattern code can be
seen on the exterior surface of the cover plate 40, and it is
possible to identify a corresponding virtual key and use it to
realize instruction input.
[0036] Further, an optical adhesive layer 20b is provided between
the light guide plate 20 and the display screen 10. The light guide
plate 20 is bonded to the display screen 10 via the optical
adhesive layer 20b; in one aspect, this enhances the stable
structure of the display screen assembly 100, in another aspect,
the light guide plate 20 is directly attached to the display screen
10; therefore, the display screen 10 and the light guide plate 20
are attached seamlessly, the display surface 11 is free of dust and
impurities, and the display effect of the display screen assembly
100 can be enhanced.
[0037] Further, the display screen assembly 100 further includes a
light source drive board 50 (for example, a strip-shaped light
source drive board). The light source drive board 50 can be deemed
as part of the lighting assembly. For instance, the light source
drive board 50 is a stripe light source drive board. The light
source drive board 50 is adjacent to the outer edge of the light
guide plate 20. The light source 20a includes multiple LED lamp
beads (not illustrated in the figures). The multiple LED lamp beads
are provided on the light source drive board 50 and are arranged
along the longitudinal direction of the light guide plate 20. The
multiple LED lamp beads are configured to emit light towards the
light guide plate 20. Specifically, the light source drive board 50
is provided with a drive circuit. When the display screen assembly
100 is applied to a terminal device, the light source drive board
50 can be electrically connected with the control assembly and
obtain a current signal via the control assembly so as to drive the
light source 20a to emit light. In this implementation, the light
source drive board 50 is adjacent to the outer side surface 23 of
the light guide plate 20. The multiple LED lamp beads are bonded to
one side of the light source drive board 50 that close to the light
guide plate 20. The light from the multiple LED lamp beads passes
through the outer side surface 23 and is diffused through the light
guide plate 20 so as to be emitted from the top surface 22. In
other implementations, the edge of the light guide plate 20 may be
exposed to the display surface 11, and the light source drive board
50 is adjacent to the bottom surface 21 that is exposed to the
display screen 10. The light of the light source 20a passes through
the bottom surface 21 and is emitted from the top surface 22.
[0038] Further, the edge of a surface on one side of the cover
plate 40 that remote from the touch panel 30 is arc-shaped. The
cover plate 40 includes an outer surface 40a provided opposite to
the inner surface 40b. The edge of the outer surface 40a is curved
in a circular arc. As one implementation, the edge of the outer
surface 40a includes an arc-shaped surface 40c curved in a circular
arc. The front projection area of the arc-shaped surface 40c at the
inner surface 40b corresponds to the non-display region 112 of the
display screen 10. Thus, by using the arc-shaped surface 40c, the
refraction angle of the light passing through the cover plate 40 of
the ink layer 42a can be changed, and it can be observed through
the cover plate 40 that the ink layer 42a is narrowing, such that
the display surface 11 of the display screen assembly 100 is
visually larger.
[0039] The present disclosure further provides a terminal front
cover 200. FIG. 3 is a schematic view of the terminal front cover
200 and FIG. 4 is a cross-sectional view of the terminal front
cover 200. The terminal front cover 200 includes a display screen
assembly 100. The terminal front cover 200 further includes a frame
60. The frame 60 is fixed to the edge of the cover plate 40.
[0040] In this implementation, the frame 60 can be made of plastic.
The thickness of the frame 60 can be thinner so as not to affect
the effective display region of the display region 111 of the
display screen assembly 100. The frame 60 can stabilize the display
screen assembly 100. When the display screen 10 is a touch display
screen, the frame 60 can also be a weak polar material. In addition
to show good insulation effect, the frame 60 can also play a role
in the transmission of fingerprint induced electric field. The
frame 60 includes an inner side surface 61. The outer side wall 43
of the cover plate 40 is fixed to the inner side surface 61.
[0041] As an implementation, the cover plate 40 can be integrally
formed with the frame 60. As an implementation, a glass raw
material member of the cover plate 40 is molded by press roll
molding, and the cover plate 40 is obtained by a cutting process.
The cover plate 40 is placed in a mold cavity of an injection mold,
and then an injection molding process is carried out so that the
frame 60 is integrally molded on the cover plate 40, such that the
outer side wall 43 is better fitted to the inner side surface 61.
The outer surface 40a of the cover plate 40 and the exterior
surface of the frame 60 are in the same mold cavity, and the outer
surface 40a and the exterior surface of the frame 60 can form a
smooth surface while the frame 60 and the cover plate 40 are more
stable in structure. In other implementations, if the frame 60 is
made of a metal material, it is also possible to place the cover
plate 40 in a mold cavity of a molding mold and inject liquid metal
into the molding mold so that the frame 60 is integrally formed
with the cover plate 40.
[0042] Further, the inner side of the frame 60 is provided with a
groove 62. The light source 20a is configured to be accommodated in
the groove 62. As one implementation, the groove 62 is arranged on
an inner side surface 61. The light source drive board 50 and the
light source 20a are fixed in the groove 62. The side wall of the
groove 62 prevents the light of the light source 20a from being
irradiated toward the frame 60 as well as the gap between the frame
60 and the cover plate 40, such that the groove 62 can prevent the
light source 20a from leaking and thereby improve the performance
of the display screen assembly 100. In the present implementation,
the light source drive board 50 is engaged with the side wall of
the groove 62. In other implementations, the light source drive
board 50 may also be bonded to the side wall of the groove 62.
[0043] In the present disclosure, according to another
implementation, there is provided a terminal 300. FIG. 5 is a
cross-sectional view of the terminal 300 according to an
implementation of the present disclosure. As illustrated in FIG. 5,
the terminal 300 includes the terminal front cover 200 as
illustrated in FIG. 3 or FIG. 4. Further, as illustrated in FIG. 5,
the terminal 300 further includes a rear cover 70 and a control
assembly 80. The rear cover 70 is provided with a receiving chamber
71, the open end of which is situated on the outer surface of the
rear cover 70. The terminal front cover 200 covers the open end,
and the display screen 10 and the control assembly 80 are received
in the receiving chamber 71. The control assembly 80 electrically
connects the display screen 10 and the light source drive board 50
so as to control the display screen 10 and the light source 20a. It
is to be understood that the terminal 300 is a terminal device,
which may be one of a mobile phone, a notebook computer, a tablet
computer, an electronic reader, an electronic album, a display and
the like.
[0044] Unless otherwise indicated, various features described in
the implementations of the present disclosure may be combined or
replaced with each other. For example, details of the elements
described in the implementations of the display screen assembly 100
can be equally applicable to the implementations of the terminal
front cover 200 and the terminal 300 of the present disclosure.
[0045] In the display screen assembly and the terminal, the light
guide plate is configured to cover the non-display region
correspondingly, and the light source is used to illuminate the
light guide plate. Besides, the light shielding band is configured
to include the keypad region and the shielding region disposed
around the keypad region. The keypad region is configured to pass
through the light of the light guide plate and is provided
corresponding to the virtual key of the touch panel. The shielding
region is configured to shield the light of the light guide plate.
In this way, the non-display region of the display screen can be
utilized and therefore the display region of the display screen
assembly can be increased effectively and is ergonomic.
[0046] In the description of the present disclosure, the term "one
implementation", "some implementations", "illustrative
implementation", "example", "specific example", or "some example"
and the like means that a particular feature, structure, material,
or characteristic described in connection with the implementation
or example is included in at least one implementation or example of
the present disclosure. In the present specification, the schematic
expression of the above-mentioned terminology does not necessarily
refer to the same implementation or example. Moreover, the
particular feature, structure, material, or feature described may
be combined in any implementation or example in any suitable
manner.
[0047] While the present disclosure has been described in detail
above with reference to the example implementations, the scope of
the present disclosure is not limited thereto. As will occur to
those skilled in the art, the present disclosure is susceptible to
various modifications and changes without departing from the spirit
and principle of the present disclosure. Therefore, the scope of
the present disclosure should be determined by the scope of the
