DETAILED DESCRIPTION
[0015] The following description includes the best mode presently
contemplated for practicing the described implementations. This
description is not to be taken in a limiting sense, but rather is
made merely for the purpose of describing general principles of
various implementations. The scope of invention should be
ascertained with reference to issued claims.
[0016] FIG. 1 shows an example of a device 100 that includes a
keyboard housing 120 and a display housing 140 that are pivotable
with respect to each other via movement about one or more hinges
132-1 and 132-2 (e.g., hinge assemblies). The device 100 may be a
device such as, for example, a computing device (e.g., an
information handling device).
[0017] As an example, the device 100 may include one or more
processors 112, memory 114 (e.g., one or more memory devices), one
or more network interfaces 116, and one or more power cells 118.
Such components may be, for example, housed with the keyboard
housing 120, the display housing 140, or the keyboard housing 120
and the display housing 140.
[0018] As shown in the example of FIG. 1, the keyboard housing 120
includes a keyboard 124 with keys 125 and the display housing 140
includes a display 144. In such an example, the keyboard 124 is
defined in a first Cartesian coordinate system as having a depth
along an x-axis (x.sub.1), a width along a y-axis (y.sub.1) and a
height or thickness along a z-axis (z.sub.1) that extends in a
direction outwardly away from touch surfaces of keys 125 of the
keyboard 124 and the display 144 is defined in a second Cartesian
coordinate system as having a depth along an x-axis (x.sub.2), a
width along a y-axis (y.sub.2) and a height or thickness along a
z-axis (z.sub.2) that extends in a direction outwardly away from a
viewing surface of the display 144. As an example, a coordinate
system may be right-handed or left-handed.
[0019] As shown in the example of FIG. 1, the one or more hinges
132-1 and 132-2 pivotably connect the keyboard housing 120 and the
display housing 140 for orienting the display housing 140 with
respect to the keyboard housing 120. For example, orientations may
include orientations definable with respect to an axis (e.g., or
axes) such as the axis .zeta. and an angle .PHI. about that
axis.
[0020] FIG. 1 shows some examples of orientations 101, 103, 105,
107 and 109. The orientations 101, 103, 105, 107 and 109 may
correspond to orientations of a clamshell computing device. The
orientation 101 may be a notebook orientation where the angle .PHI.
is about 90 degrees or more (e.g., or optionally somewhat less than
about 90 degrees depending on position of a user, etc.). As shown,
for the orientation 101, a user may use a finger or fingers of one
or both hands to depress keys 125 of the keyboard 124 (e.g., touch
typing), for example, while viewing information being rendered to
the display 144 of the display housing 140 (e.g., using the one or
more processors 112, the memory 114, etc. that may be included in
the keyboard housing 120, the display housing 140 or both).
[0021] As an example, the keyboard housing 120 may include a
frontal surface 122 and may include a touch input surface 123
(e.g., of a touch input device such as a touchpad). As an example,
the keyboard 124 may include one or more other input devices (e.g.,
a control stick, etc.). As an example, the frontal surface 122 may
be a surface suitable for resting a palm or palms of a hand or
hands. For example, as shown in FIG. 1, the touch input surface 123
can be defined by x and y dimensions where a left palm rest surface
is to the left of the touch input surface 123 and where a right
palm rest surface is to the right of the touch input surface 123.
In such an example, the left and right palm rest surfaces may be
defined by respective x and y dimensions as well as a spacing
therebetween. Where a device does not include a touch input surface
such as the touch input surface 123, the frontal surface 122 may
extend in the y direction approximately from a left side of the
keyboard housing 120 to a right side of the keyboard housing. Such
a surface can be a left and right palm rest surface.
[0022] As to the orientation 103, it may correspond to a display
orientation for viewing the display 144 where the keyboard 124
faces downward and the device 100 is supported by the keyboard
housing 120 (e.g., by a rim about the keyboard 124, the frontal
surface 122, etc.). As to the orientation 105, it may correspond to
a "tent" orientation where the display 144 faces outwardly for
viewing on one side of the tent and the keyboard 124 of the
keyboard housing 120 faces outwardly on the other side of the
tent.
[0023] The orientation 107 may be a tablet orientation where the
angle .PHI. is about 360 degrees such that a normal outward vector
N.sub.1 of the keyboard 124 of the keyboard housing 120 and a
normal outward vector N.sub.2 of the display 144 of the display
housing 140 are oriented in oppositely pointing directions,
pointing away from each other; whereas, in contrast, for a closed
orientation of the device 100 (e.g., where the angle .PHI. is about
0 degrees), the vectors N.sub.1 and N.sub.2 would be pointing
toward each other.
[0024] The orientation 109 may be a planar orientation where the
angle .PHI. is about 180 degrees such that a normal outward vector
N.sub.1 of the keyboard 124 of the keyboard housing 120 and a
normal outward vector N.sub.2 of the display 144 of the display
housing 140 are oriented in approximately the same pointing
directions.
[0025] Various computing devices such as laptop, or notebook,
computing devices can be characterized at least in part by a
footprint. For example, the device 100 of FIG. 1 may be
characterized at least in part by dimensions in x and y as to the
keyboard housing 120 and/or as to the display housing 140. As an
example, a footprint can be an area that can be defined by a plane
in the x and y directions of the Cartesian coordinate systems shown
in FIG. 1.
[0026] A user may utilize a device that can execute a number of
applications where one or more of the applications can call for
rendering information to a display. The U.S. Department of Labor
Occupational Health and Safety Administrations provides guidance
for viewing a display (e.g., a monitor), including use of a viewing
distance that is between 20 inches and 40 inches (50 cm and 100 cm)
from the eye to the front surface of the display. A user in an
ergonomic seating position with the device 100 on a desk may have a
viewing angle of about 40 degrees to about 50 degrees (e.g., angle
from the display 144 to the user's eyes).
[0027] FIG. 2 shows an example of a device 200 in two orientations,
which can be referred to as a closed orientation (top) and an open
orientation (bottom). As shown, the device 200 can include a
folding case 210 that includes a fold region 213 that defines a
first portion 215-1 and a second portion 215-2 of the folding case
210; a housing 211 disposed on the first portion 215-1 of the
folding case 210 where the housing 211 can include a processor 212,
memory 214 operatively coupled to the processor 212, and a keyboard
224 operatively coupled to the processor 212; and a flexible
display 241 operatively coupled to the processor 212 and disposed
in part on the first portion 215-1 of the folding case 210 and
disposed in part on the second portion 215-2 of the folding case
210. The device 200 can transition from the closed orientation to
the open orientation via curvature of the fold region 213. The fold
region 213 can define a radius of curvature for the closed
orientation of the device 200 and can define a radius of curvature
for the open orientation of the device. As an example, the device
200 may be orientable in a plurality of open orientations.
[0028] In the example of FIG. 2, the device 200 can be defined at
least in part by a keyboard portion 220, a foldable portion 230 and
a display portion 240 where the display 241 and include a portion
242 that can be substantially planar to the keyboard portion 220, a
portion 244 that can be adaptable to curvature of the folded
portion 230, and a portion 246 that can be substantially planar to
the display portion 240. As shown in FIG. 2, the display 241 can
span a portion of the first portion 215-1 of the folding case 210
(see, e.g., the portion 242 of the display 241), the fold region
213 of the folding case 210 (see, e.g., the portion 244 of the
display 241) and a portion of the second portion 215-2 of the
folding case 210 (see, e.g., the portion 246 of the display
241).
[0029] As an example, a user in an ergonomic seating position with
the device 200 on a desk may have a viewing angle of about 40
degrees to about 50 degrees (e.g., angle from display portion 246
to the user's eyes). In such an example, the user can view the
display portion 242 and the display portion 244 (e.g., when seated
at a distance of between approximately 20 inches and approximately
40 inches (e.g., approximately 50 cm and approximately 100 cm) from
the eye to the front surface of the display portion 246).
[0030] As an example, the device 200 can include one or more
processors 212, memory 214 accessible by at least one of the one or
more processors 212; one or more network interfaces 216 and one or
more power cells 218. In the example of FIG. 2, the housing 211 can
be a keyboard housing that houses at least a portion of the
keyboard 224. As an example, the housing 211 can be a circuitry
housing that includes a display interface that can be operatively
coupled to one or more displays. In such an example, the circuitry
can include display circuitry such as one or more graphics
processors (e.g., cores, etc.). As an example, memory can be
accessible to display circuitry where the display circuitry can
render information from the memory to one or more displays. As an
example, display circuitry may optionally render information to one
or more of the portions 242, 244 and 246 of the display 241. As an
example, one or more of the portions 242, 244 and 246 of the
display 241 may be a touchscreen display portion. For example, the
portion 242 can be a touchscreen display where a user may extend a
finger or fingers from the keyboard 224 and touch the portion 242,
for example, such that the device 200 receives touch input (e.g.,
via approach touch sensing circuitry).
[0031] In the example of FIG. 2, the device 200 may be referred to
as an asymmetrically folding display device because the display 241
has the portion 244 that spans the fold region 213 of the foldable
case 210. In FIG. 1, the keyboard housing 120 area (e.g.,
footprint) is substantially the same as the display housing 140
area and the display 144 is confined by the display housing 140.
The device 100 of FIG. 1 can be substantially symmetrical with
respect to the two housings 120 and 140 as coupled by the one or
more hinges 132-1 and 132-2.
[0032] The display 241, or at least the portion 244, can be a
flexible display. As an example, a flexible display may be a
flexible electronic paper based display. As an example, a flexible
display may be a flexible Organic Light Emitting Diode (OLED) based
display (e.g., FOLED). FOLED can include a flexible plastic
substrate on which electroluminescent organic semiconductor is
deposited. Such a flexible display can be bent or rolled,
optionally while operating.
[0033] An OLED emits light due to the electroluminescence of thin
films of organic semiconductors that may be approximately 100 nm
thick. OLEDs may be fabricated on a glass substrate and/or a
flexible plastic such as polyethylene terephthalate (PET) and/or
another type of polymeric material. As an example, a flexible OLED
display can be fabricated by deposition of an organic layer onto a
substrate, optionally using a printing type of method.
[0034] As an example, an OLED display can be made up of a layer of
organic material placed between two conductors. In such an example,
the two conductors (an anode and a cathode) can be between a glass
top plate (seal) and a glass bottom plate (substrate). When an
electric current is applied to the two conductors, the organic
material produces a bright, electro-luminescent light. When energy
passes from the negatively charged layer (cathode) to the other
(anode) layer, it stimulates the organic material between the two,
which in turns emits lights that is visible through the outermost
layer of glass.
[0035] To produce color, an electric current can be applied to
stimulate relevant pixels on the OLED display. Pixels can be
created by an arrangement of the cathodes and anodes; which can be
arranged perpendicular to each other. The electric current applied
to the selected strips of anodes and cathodes determine which
pixels get turned on and which pixels remain off and brightness of
each pixel can be proportional to the amount of applied
current.
[0036] A color OLED can include a metal cathode with a negative
charge, an electron transport layer, organic material, a hole
transport layer, and an anode with a positive charge. Each pixel of
a color OLED may be divided into red, green, and blue sub-pixels.
When a controller (e.g., display circuitry) applies an electric
current to a particular pixel, the current passes through the
organic material causing the material to emit light. By adjusting
the intensity of the electric current in each red, green, and blue
sub-pixel, specific colors and gradients can be created.
[0037] As to the device 200 of FIG. 2, as mentioned, it can be
asymmetric with respect to the fold region 213 and the display 241.
Such an approach can allow for a reduction in the footprint of the
device 200 when compared to, for example, the device 100 of FIG.
1.
[0038] In the open orientation of FIG. 2 (e.g., an open clamshell
mode), the bottom portion 242 of the display 241 is within easy
reach of a user's hands on the keyboard 224. The short reach to the
portion 242 of the display 241 affords better interaction where the
portion 242 is a touch-enabled screen.
[0039] In the open orientation of FIG. 2, there is viewability of
and ease of interaction with the open, curved display 241 where a
curve may be defined at least in part via a radius of curvature.
Such a curve may be formed via the fold region 213 of the foldable
case 210. For example, the fold region 213 may include material
that can be formed and hold its form. For example, a chain link
type of hinge may be a friction hinge that can be formed via links
and axles and hold its form via friction. As an example, the fold
region 213 may include a malleable material that can be formed and
hold its form. Such a material may include metallic material and/or
polymeric material.
[0040] As an example, the fold region 213 may be adjustable as to
its outer dimension, which may, for example, be defined in part by
a radius (e.g., of a semi-circular profile, a semi-elliptical
profile, a semi-oval profile, etc.). In such an example, the fold
region 213 may optionally be folded to a shape that is comfortably
grippable (e.g., graspable) by a single hand.
[0041] As an example, with respect to the first portion 215-1 of
the foldable case 210, it may include a touchpad. For example, the
first portion 215-1 of the foldable case 210 can include a housing
or housings that house the keyboard 224 and/or a touchpad. As an
example, the keyboard 224 may include a pointable controller (e.g.,
a TRACKPOINT.TM. controller).
[0042] FIG. 3 shows the device 200 in a closed orientation in a
side view and in a perspective view where it is grasped by a hand
201. In the side view, the device 200 can be defined in part by
various dimensions: a bottom side depth x.sub.c1, a corresponding
top side depth x.sub.c2, a keyboard depth x.sub.h, a display
portion depth x.sub.f, a closed end thickness z.sub.c1, a fold
region thickness z.sub.c2, an inner radius r.sub.i and an outer
radius r.sub.o.
[0043] As to grippability, a table 300 in FIG. 3 shows some
examples of tennis racquet grips in terms of circumference. As an
example, a circumference of approximately 100 mm corresponds to an
outer radius of approximately 15 mm (e.g., a diameter of
approximately 30 mm). As an example, an outer radius can be greater
than or equal to approximately 15 mm for grippability (e.g.,
graspability).
[0044] As mentioned, the device 200 may include a fold region that
can be adaptable. For example, a chain link hinge may be set to a
desired radius of curvature, for example, to match a hand size. A
hand size may be a child's hand size or an adult's hand size. As an
example, a device may be orderable (e.g., manufacturable) in sizes,
which may include standardized sizes such as the European sizes for
tennis racquet hand grips.
[0045] As shown in FIG. 3, in the closed orientation, a gap can
exist between portions of the device 200. For example, a
substantially trapezoid gap or substantially triangular gap may be
defined in part by a larger dimension near the foldable portion 230
(see, e.g., r.sub.i) and a smaller dimension near where the ends
come together (see, e.g., z.sub.c1), which may be approximately
zero or zero where contact occurs. As shown in the example of FIG.
3, keys of the keyboard 224 may extend away from the keyboard
portion 220 and toward the display portion 240 where, in the closed
orientation, at least some of the keys, if not all of the keys, do
not contact the display portion 240. For example, the device 200
can be dimensioned such that at least some keys, if not all keys,
of the keyboard 224 do not contact a surface of a display of the
display portion 240 when the device 200 is in a closed orientation.
Such an arrangement can help to reduce risk of key surfaces
contacting and marking a display surface. As shown in FIG. 3, where
the keyboard 224 includes a control tool 229 that extends
substantially perpendicular to the keyboard 224, optionally to an
extent that is above upper surfaces of keys of the keyboard 224,
the formation of the gap in the closed orientation can reduce risk
of the control tool 229 from contacting a surface of a display of
the display portion 240. While keys and a control tool are
mentioned, the gap may provide for one or more other features
(e.g., components, etc.) that can be disposed within the gap where,
for example, a reduced risk (e.g., or no risk) exists under normal
user conditions for marring of a surface of a display (e.g., as
caused by contact, contact and movement, etc.).
[0046] In the example of FIG. 3, the device 200 may include one or
more magnets. For example, the device 200 may include one or more
magnets that can provide a magnetic attraction force that can help
to maintain the device 200 in the closed orientation, for example,
during transport, while in a suitcase, a bag, etc. For example, one
or more of the edges of the device 200 can include ferromagnetic
material that includes at least one magnet. In such an example, a
user folds the device 200, the materials can come close enough for
interaction of a magnetic attraction force. In such an example, the
device 200 may "snap-close". As an example, such a force may be
overcome via force of a hand where one or more fingers of the hand
may, for example, be inserted into a gap of the device 200 between
the portions 220 and 240 to apply force sufficient to overcome the
magnetic attraction force. As an example, a device may include a
material such as VELCRO.TM. that can help maintain the device in a
closed orientation. As an example, a device can include a clip or
clips that may help maintain the device in a closed orientation. As
an example, a device can include a fold region that can include a
structure that allows for folding and retention in a folded state
and that allows for unfolding and retention in an unfolded state.
Such a structure may, for example, include components that contact
with friction therebetween where the frictional force is sufficient
to maintain the device in an unfolded state or in an folded state
as a stand-alone state (e.g., resting on a desk, in a bag, in a
suitcase, etc.).
[0047] FIG. 4 shows an example of a fold region 410 and an example
of a fold region 430. The fold region 410 can be formed via a
plurality of axles that are operatively coupled via links. The fold
region 410 may be referred to as a watchband type of fold region or
a watchband hinge assembly. The example fold region 410 includes
four intermediate axles and two end axles. The number and size of
axles may be selected to form a desired radius of curvature.
Further, such a fold region can include one or more limiters, which
may be surfaces of components that contact to define a minimum
radius of curvature for a closed orientation of a device.
[0048] As to the fold region 430, it includes a plurality of axles
and links where the links are shaped to define a minimum radius of
curvature for a closed orientation of a device. Such a fold region
may be referred to as a lobster hinge assembly, for example, where
it includes plates that extend across hinges where the plates can
slide with respect to each other.
[0049] As an example, a fold region can include a hinge assembly
that is metallic, polymeric and/or ceramic. For example, a
watchband hinge assembly can include polymeric axles and polymeric
links or, for example, metallic axles and polymeric links, or, for
example, polymeric axles and metallic links. As an example, a hinge
assembly of a fold region may be coated at least in part by one or
more coatings and/or covered at least in part by one or more
covers. As mentioned, a fold region may include features that are
anti-slip, anti-rotation, etc. that can function to add stability
to a device when it is in an open orientation. As an example, one
or more ribs may extend in a manner akin to the plates of the fold
region 430 where the one or more ribs may extend a distance
outwardly. As an example, the fold region 410 and/or the fold
region 430 can provide component to component contact with an
amount of friction that is sufficient to maintain the device 200
(e.g., where including a fold region such as, for example, the fold
region 410, the fold region 430, etc.) in one or more states.
[0050] FIG. 5 shows an example of the device 200 in an open
orientation. As shown, the open orientation can be defined by one
or more dimensions such as, for example, a radius of curvature
r.sub.i and an arc angle .PHI. of a curved portion of the foldable
display 241.
[0051] In the example of FIG. 5, the device 200 can be seated on a
substantially planar surface such as a surface of a table or a
desk. In such an example, the footprint of the device 200 may be
enlarged when compared to the closed orientation shown in FIG. 3.
In such an example, upon transitioning the device 200 from the
closed orientation to the closed orientation, the footprint of the
device 200 can be enlarged and, by being enlarged, can increase
stability of the device 200. For example, the increase in stability
via an enlarged footprint may help to resist tilting of the device
200 responsive to force applied by a finger touching the display
241. Further, where a user may apply an excessive touch to the
display 241, the device 200 can merely rotate, for example, about
an axis that may be defined by an origin of the radius of
curvature.
[0052] A depth of the footprint of the device 200 can be defined by
the dimensions x.sub.h, x.sub.f and x.sub.s where the dimension
x.sub.s may be an enlarged portion when the device 200 is in the
open orientation shown in FIG. 5. FIG. 5 further shows a total
dimension in the x-direction as x.sub.t and a curved portion
dimension x.sub.c. As an example, the device 200 can be defined in
the open orientation of FIG. 5 via a hypotenuse that is defined as
a line between open ends of the device 200 (see, e.g., dashed line
extending from an upper end to a lower end). In such an example,
the device 200 may be defined with respect to a triangle where
various angles are formed and where a radius of curvature (e.g.,
r.sub.i) may be defined with respect to a vertex (e.g., a corner)
of the triangle. Various features of the device 200 may be defined
with respect to one or more dimensions, angles, etc., as shown in
the view of FIG. 5.
[0053] As shown in the example of FIG. 5, opposing ends of the
device 200 can define a straight line where an origin of a radius
of curvature of the fold region 213 may coincide with the straight
line. As shown in FIG. 5, the arc angle of the fold region 213
(e.g., the display portion 244) may be less than approximately 90
degrees. As to an angle formed by the keyboard 224 and the display
portion 246, it is shown to be greater than 90 degrees in the
example of FIG. 5.
[0054] In FIG. 5, the height of the device 200 can be defined by
the dimension z.sub.c2, while a thickness of the device 200 may be
defined by the dimension z.sub.c1. As an example, the fold region
213 of the foldable case 210 may optionally include one or more
features that may help to prevent rotation of the device 200. For
example, an outer surface of the fold region 213 can include ridges
(e.g., ribs, etc.). As an example, the outer surface of the
foldable case 210 may be a rubberized surface (e.g., an elastomeric
surface). Such a surface may increase friction coefficient (e.g.,
dynamic coefficient of friction) to help the device 200 resist
sliding along a surface and/or to facilitate grip in a hand of a
user.
[0055] FIG. 6 shows a front view of the device 200 in an open
orientation where the display portions 244 and 246 are visible.
FIG. 6 also shows an example of the housing 211 along with various
components (e.g., circuitry, a battery, interface(s), etc.). As an
example, the housing 211 can include an interface for a flexible
display such as a FOLED display. For example, such an interface may
provide for transmission of information and/or power. As an
example, a flexible display can include an electrical plug that can
be inserted into a receptacle, which can be an electrical interface
to operatively couple the flexible display to other circuitry
(e.g., circuitry of the housing 211, etc.). The device 200 can
include a housing such as the housing 211 that operatively couples
to a flexible display such as the display 241, which can include
portions 242, 244 and 246. In such an example, the housing 211 and
the display 241 can be coupled to a foldable case that includes a
fold region (see, e.g., the fold region 410 and the fold region
430). As an example, the housing 211 may include one or more
sockets for one or more electrical components (e.g., USB, video,
audio, power, memory, etc.).
[0056] FIG. 7 shows a plan view of the device 200 in an open
orientation where the display portions 242, 244 and 246 are
visible. As shown, one or more graphic controls 243 may be rendered
to the display portion 242 where such one or more graphic controls
243 may respond to receipt of touch input by the device 200 (e.g.,
via a touchscreen display). As shown in FIG. 7, a hand 201 includes
a fingertip 203 where the device 200 can detect touch input from
the fingertip 203 when a user touches one of the graphic controls
243. As shown, the hand 201 can be positioned in a manner where
fingers can be readily positioned for typing using the keyboard 224
of the device 200. In the example of FIG. 7, a dimension 4x is
shown as a distance from a key of the keyboard 224 to one of the
one or more graphic controls 243. Such a dimension may be, for
example, approximately a key-to-key distance or, for example, less
than approximately 300 percent of a key-to-key (e.g., key
center-to-key center) distance, or, for example, less than
approximately 200 percent of a key-to-key (e.g., key center-to-key
center) distance. Such a distance may be convenient for a user to
move from the keyboard 224 to one or more of the one or more
graphic controls 243.
[0057] FIG. 8 shows a perspective view of the device 200 in an open
orientation where display portions 242, 244 and 246 are visible. As
an example, the device 200 can render information to one or more of
the display portions 242, 244 and 246. As an example, an
application can be executed in an operating system environment
established at least in part via a processor of the device 200. In
such an example, the application can include one or more control
bars (e.g., toolbars) that can be renderable in one or more of the
display portions 242, 244 and 246. As an example, consider a photo
editing program where a photo is rendered to the display portion
246 and where information is rendered to the portion 244 and one or
more tools are rendered to the display portion 242. In such an
example, a user may view information in the display portion 244
germane to editing of the photo rendered to the portion 246 while
selecting one or more tools via the portion 242.
[0058] As an example, an application can include a curved display
mode of operation where the device 200 can render one or more
graphical user interfaces to one or more portions of the display
241, which may facilitate user interactions given the curvature of
the display 241, the curved portion 244 of the display 241 and/or
one or more substantially flat portions 242 and 246 of the display
241.
[0059] FIG. 9 shows an example of a portion of a display 960, which
may be a portion of a flexible display or a display that includes a
flexible portion. As shown, the portion of the display 960 includes
panels 1, 2 to N, which may be user defined or otherwise defined
(e.g., via an application, etc.). FIG. 9 also shows example GUIs
901, 902, 903, 904 and 805, which may optionally be assigned to one
or more panels of the display portion 960. The GUI 901 shows
information such as weather and/or traffic information, which may
be from a service (e.g., an Internet service, a cellular service,
etc.). The GUI 902 shows information associated with email. The GUI
903 shows information associated with a connection, power and time,
which may be that of a device or a device that is in communication
with the display portion 960. The GUI 904 shows messaging
information. The GUI 905 shows a keypad graphic with keys that may
be utilized, for example, for numeric entry to perform one or more
operations (e.g., dial a phone number, operate a calculator,
etc.).
[0060] As an example, the display portion 960 may correspond to the
display portion 242, which can be readily accessible for touch
input and/or may correspond to the display portion 244, which may
be accessible as well for touch input. As an example, the display
portion 244 may include information that helps to identify a
touchable control of the display portion 242. In such an example,
where functions are associated with an application, the application
may be executable to render information to the display portion 244
that explains, identifies, etc., one or more touch controls that
can be interacted with via the display portion 242.
[0061] As an example, a device can include a folding case that
includes a fold region that defines a first portion and a second
portion of the folding case; a housing disposed on the first
portion of the folding case where the housing includes a processor,
memory operatively coupled to the processor, and a keyboard
operatively coupled to the processor; and a flexible display
operatively coupled to the processor and disposed in part on the
first portion of the folding case and disposed in part on the
second portion of the folding case. In such an example, the device
can be referred to as an asymmetric display device as the flexible
display can be a contiguous display that spans a fold region. As an
example, for an end to end length of the device, the flexible
display can be a contiguous display that may be of a length that is
greater than approximately 50 percent of the end to end length of
the device (e.g., in the x-direction as shown in various examples
such as those of FIG. 3 and FIG. 5).
[0062] As an example, a device can include a folded state and an
unfolded state. In such an example, in the folded state, a first
portion of a folding case can define a folded footprint of the
device and, for example, in the unfolded state, the first portion
of the folding case and a portion of a second portion of the
folding case define an unfolded footprint of the device. As an
example, an unfolded state footprint of a device can be larger than
a folded footprint of the device. For example, the unfolded state
footprint of the device can be at least approximately 5 percent
greater than the folded state footprint of the device. As an
example, an area of a footprint of a device in a folded state can
be less than a display area of a flexible display of the
device.
[0063] As an example, a first portion of a device may be a first
half of a folding case of the device and a second portion of the
device may be a second half of the folding case. In such an
example, the device may be defined as being symmetric with respect
to folding; however, as mentioned a device can be asymmetric with
respect to a flexible display as such a flexible display can be in
part in a first portion, which may be a first half, and in part in
a second portion, which may be a second half. As an example, a
device may be a symmetric folding device with respect to a case and
an asymmetric device with respect to a display thereof. In such an
example, the folding of the device folds the display (e.g., at
least a portion of the display is flexible to form a curve).
[0064] As an example, a device can, in a folded state, form a gap
that can separate moveable components (e.g., keyboard keys, a
control tool, etc.) of one portion of the device and a surface of
another portion of the device. In such an example, the gap may be
triangular in cross-sectional shape, trapezoidal in cross-sectional
shape, etc. As an example, a gap may help to reduce risk of marring
of a surface of a display when the device is in a closed
orientation. Further, the gap may comport with a shape of the
device that is suitable for gripping by a hand (see, e.g., examples
of FIG. 3).
[0065] As an example, a device can include a flexible display that
is or that includes a touchscreen display. In such an example, in
an unfolded state, a first portion of a folding case of the device
and a portion of a second portion of the folding case can define an
unfolded footprint of the device, larger than a folded footprint of
the device, that increases physical stability of the device on a
horizontal surface in the unfolded state.
[0066] As an example, a device can include a rigid housing. For
example, a rigid housing may support a keyboard, which may include
depressible keys that receive force via touch-typing. As an
example, a rigid housing can include one or more electronic
components, which may be and/or include circuitry. For example,
consider a rigid housing that includes a battery, which may be a
lithium-ion battery. As an example, a rigid housing can include one
or more interfaces that, for example, may be or include one or more
plug-in interfaces that can receive plugs to operatively couple one
or more components to circuitry carried by the rigid housing. For
example, consider a serial interface such as a USB type of
interface, an audio interface, a video interface, a memory card
interface, a power supply interface, etc.
[0067] As an example, a housing of a device can be constructed at
least in part or, for example, wholly from a metallic material. As
an example, a folding case of a device can be constructed at least
in part or, for example, wholly from an elastomeric material. As an
example, a device can include an elastomeric material as a surface
that is an exterior surface that can provide for grippability
(e.g., via increase coefficient of friction with respect to one or
more fingers of a hand, which can include the thumb as a finger).
In such an example, the device can include a rigid housing that
includes components, which may be, for example, protected at least
in part by the rigidity of the housing (e.g., consider a crush
resistant housing as may be associated with a smartphone that is
susceptible to being sat on by a user when in a back pocket of the
user's pants).
[0068] As an example, a device can include a flexible display that
is an OLED display (e.g., a FOLED display, etc.).
[0069] As an example, a device can include instructions stored in
memory and executable by a processor to render a graphical user
interface to a flexible display of the device where the graphical
user interface includes a control bar portion rendered to a portion
of the flexible display that is disposed on a first portion of a
folding case of the device. In such an example, the first portion
can include a keyboard where keys are spaced at a distance from one
another to define a key-to-key spacing. In such an example, a
spacing can be defined from an upper key (e.g., in an upper row of
keys) and one or more graphical controls of the control bar
portion. In such an example, the spacing can be defined by a
distance that can be less than approximately 300 percent than the
key-to-key spacing (see, e.g., the example of FIG. 7). Such an
arrangement can allow for a user to extend a finger or fingers
while touch-typing to touch and thereby cause the device to receive
touch input associated with one or more of the one or more
graphical controls of the control bar portion. In such an example,
the device may respond to the touch input to perform one or more
actions. As an example, a user may rest a palm of a hand on a palm
rest portion of a device that is below a set of keys of a keyboard
of the device (e.g., in the x-direction) and, while the palm is
resting on the palm rest portion, the user may extend a finger from
the set of keys of the keyboard to a position above the set of keys
of the keyboard (e.g., in the x-direction) to touch a portion of a
display that is part of an overall flexible display of the device.
As an example, a portion of a display of a device can be a curved
portion, which may be a touchscreen display portion. In such an
example, a user may extend a finger of a hand forward, optionally
while maintaining a palm of the hand resting on a palm rest portion
of the device (see, e.g., the display portion 244 of the example of
FIG. 7 where the finger may extend further forward in the
x-direction to contact the display portion 244).
[0070] As an example, a device can include a folding region that
defines a minimum radius of curvature, for example, in a closed
orientation of the device. In such an example, the folding region
may be limited to a maximum radius of curvature in an open
orientation, for example, via one or more mechanisms that may be
part of a folding region. As an example, a device may include a
folding region that allows the device to be opened to a
substantially planar open orientation where a flexible display
transitions from open orientations where a portion of the flexible
display is curved to a substantially planar orientation where the
portion of the flexible display is substantially planar (e.g., to
form a planar display of the device).
[0071] As an example, a device can include an unfolded state where
at least a portion of a flexible display that is disposed in part
on a first portion of a folding case of the device is co-planar
with a plane of a keyboard of the first portion.
[0072] As an example, a device can include an unfolded state where
a flexible display includes a bend that is greater than
approximately 90 degrees and less than approximately 180 degrees.
Such an unfolded state can correspond to an open orientation of the
device (see, e.g., the example of FIG. 5).
[0073] As an example, a device may include an unfolded state where
a flexible display of the device is substantially co-planar with a
plane of a keyboard of the device.
[0074] As an example, a device can include a fold region of a
folding case that includes support features. In such an example, in
the unfolded state, at least a portion of the support features may
be substantially co-planar with a plane of a first portion of the
folding case (e.g., a keyboard portion of the device). As an
example, a support feature can be a rib, a nib, etc., as a feature
that may extend away from the fold region to support the device on
a surface (e.g., footprint support) when the device is in an open
orientation (see, e.g., the example of FIG. 5). As an example, a
support feature of a fold region of a device may be comfortable to
a palm of a hand when the device is held by the hand (see, e.g.,
the example of FIG. 3). For example, a support feature may be made
of an elastomeric material that does not dig into the skin of a
palm of a hand in a manner that would be uncomfortable to a user
(e.g., which may cause a user discomfort, desire to release the
device, etc.).
[0075] The term "circuit" or "circuitry" is used in the summary,
description, and/or claims. As is well known in the art, the term
"circuitry" includes all levels of available integration (e.g.,
from discrete logic circuits to the highest level of circuit
integration such as VLSI, and includes programmable logic
components programmed to perform the functions of an embodiment as
well as general-purpose or special-purpose processors programmed
with instructions to perform those functions) that include at least
one physical component such as at least one piece of hardware. A
processor can be circuitry. Memory can be circuitry. Circuitry may
be processor-based, processor accessible, operatively coupled to a
processor, etc. Circuitry may optionally rely on one or more
computer-readable media that includes computer-executable
instructions. As described herein, a computer-readable medium may
be a storage device (e.g., a memory chip, a memory card, a storage
disk, etc.) and referred to as a computer-readable storage medium,
which is non-transitory and not a signal or a carrier wave.
[0076] While various examples of circuits or circuitry have been
discussed, FIG. 10 depicts a block diagram of an illustrative
computer system 1000. The system 1000 may be a desktop computer
system, such as one of the ThinkCentre.RTM. or ThinkPad.RTM. series
of personal computers sold by Lenovo (US) Inc. of Morrisville,
N.C., or a workstation computer, such as the ThinkStation.RTM.,
which are sold by Lenovo (US) Inc. of Morrisville, N.C.; however,
as apparent from the description herein, a satellite, a base, a
server or other machine may include other features or only some of
the features of the system 1000. As an example, the device 200 of
FIG. 2, etc., can include one or more features of the system 1000
of FIG. 10.
[0077] As shown in FIG. 10, the system 1000 includes a so-called
chipset 1010. A chipset refers to a group of integrated circuits,
or chips, that are designed (e.g., configured) to work together.
Chipsets are usually marketed as a single product (e.g., consider
chipsets marketed under the brands INTEL.RTM., AMD.RTM., etc.).
[0078] In the example of FIG. 10, the chipset 1010 has a particular
architecture, which may vary to some extent depending on brand or
manufacturer. The architecture of the chipset 1010 includes a core
and memory control group 1020 and an I/O controller hub 1050 that
exchange information (e.g., data, signals, commands, etc.) via, for
example, a direct management interface or direct media interface
(DMI) 1042 or a link controller 1044. In the example of FIG. 10,
the DMI 1042 is a chip-to-chip interface (sometimes referred to as
being a link between a "northbridge" and a "southbridge").
[0079] The core and memory control group 1020 include one or more
processors 1022 (e.g., single core or multi-core) and a memory
controller hub 1026 that exchange information via a front side bus
(FSB) 1024. As described herein, various components of the core and
memory control group 1020 may be integrated onto a single processor
die, for example, to make a chip that supplants the conventional
"northbridge" style architecture.
[0080] The memory controller hub 1026 interfaces with memory 1040.
For example, the memory controller hub 1026 may provide support for
DDR SDRAM memory (e.g., DDR, DDR2, DDR3, etc.). In general, the
memory 1040 is a type of random-access memory (RAM). It is often
referred to as "system memory".
[0081] The memory controller hub 1026 further includes a
low-voltage differential signaling interface (LVDS) 1032. The LVDS
1032 may be a so-called LVDS Display Interface (LDI) for support of
a display device 1092 (e.g., a CRT, a flat panel, a projector,
etc.). A block 1038 includes some examples of technologies that may
be supported via the LVDS interface 1032 (e.g., serial digital
video, HDMI/DVI, display port). The memory controller hub 1026 also
includes one or more PCI-express interfaces (PCI-E) 1034, for
example, for support of discrete graphics 1036. Discrete graphics
using a PCI-E interface has become an alternative approach to an
accelerated graphics port (AGP). For example, the memory controller
hub 1026 may include a 16-lane (.times.16) PCI-E port for an
external PCI-E-based graphics card. A system may include AGP or
PCI-E for support of graphics. As described herein, a display may
be a sensor display (e.g., configured for receipt of input using a
stylus, a finger, etc.). As described herein, a sensor display may
rely on resistive sensing, optical sensing, or other type of
sensing.
[0082] The I/O hub controller 1050 includes a variety of
interfaces. The example of FIG. 10 includes a SATA interface 1051,
one or more PCI-E interfaces 1052 (optionally one or more legacy
PCI interfaces), one or more USB interfaces 1053, a LAN interface
1054 (more generally a network interface), a general purpose I/O
interface (GPIO) 1055, a low-pin count (LPC) interface 1070, a
power management interface 1061, a clock generator interface 1062,
an audio interface 1063 (e.g., for speakers 1094), a total cost of
operation (TCO) interface 1064, a system management bus interface
(e.g., a multi-master serial computer bus interface) 1065, and a
serial peripheral flash memory/controller interface (SPI Flash)
1066, which, in the example of FIG. 10, includes BIOS 1068 and boot
code 1090. With respect to network connections, the I/O hub
controller 1050 may include integrated gigabit Ethernet controller
lines multiplexed with a PCI-E interface port. Other network
features may operate independent of a PCI-E interface.
[0083] The interfaces of the I/O hub controller 1050 provide for
communication with various devices, networks, etc. For example, the
SATA interface 1051 provides for reading, writing or reading and
writing information on one or more drives 1080 such as HDDs, SDDs
or a combination thereof. The I/O hub controller 1050 may also
include an advanced host controller interface (AHCI) to support one
or more drives 1080. The PCI-E interface 1052 allows for wireless
connections 1082 to devices, networks, etc. The USB interface 1053
provides for input devices 1084 such as keyboards (KB), one or more
optical sensors, mice and various other devices (e.g., microphones,
cameras, phones, storage, media players, etc.). On or more other
types of sensors may optionally rely on the USB interface 1053 or
another interface (e.g., I.sup.2C, etc.). As to microphones, the
system 1000 of FIG. 10 may include hardware (e.g., audio card)
appropriately configured for receipt of sound (e.g., user voice,
ambient sound, etc.).
[0084] In the example of FIG. 10, the LPC interface 1070 provides
for use of one or more ASICs 1071, a trusted platform module (TPM)
1072, a super I/O 1073, a firmware hub 1074, BIOS support 1075 as
well as various types of memory 1076 such as ROM 1077, Flash 1078,
and non-volatile RAM (NVRAM) 1079. With respect to the TPM 1072,
this module may be in the form of a chip that can be used to
authenticate software and hardware devices. For example, a TPM may
be capable of performing platform authentication and may be used to
verify that a system seeking access is the expected system.
[0085] The system 1000, upon power on, may be configured to execute
boot code 1090 for the BIOS 1068, as stored within the SPI Flash
1066, and thereafter processes data under the control of one or
more operating systems and application software (e.g., stored in
system memory 1040). An operating system may be stored in any of a
variety of locations and accessed, for example, according to
instructions of the BIOS 1068. Again, as described herein, a
satellite, a base, a server or other machine may include fewer or
more features than shown in the system 1000 of FIG. 10. Further,
the system 1000 of FIG. 10 is shown as optionally include cell
phone circuitry 1095, which may include GSM, CDMA, etc., types of
circuitry configured for coordinated operation with one or more of
the other features of the system 1000. Also shown in FIG. 10 is
battery circuitry 1097, which may provide one or more battery,
power, etc., associated features (e.g., optionally to instruct one
or more other components of the system 1000). As an example, a
SMBus may be operable via a LPC (see, e.g., the LPC interface
1070), via an I.sup.2C interface (see, e.g., the SM/I.sup.2C
interface 1065), etc.
[0086] Although examples of methods, devices, systems, etc., have
been described in language specific to structural features and/or
methodological acts, it is to be understood that the subject matter
defined in the appended claims is not necessarily limited to the
specific features or acts described. Rather, the specific features
and acts are disclosed as examples of forms of implementing the
claimed methods, devices, systems, etc.
