Hereinafter, embodiments of the present disclosure will be described in detail with reference to
the drawings. The description will be made in the following order. 1. Embodiment (example of
display device in which a display body is attached to a bezelless front plate and forms a curved
shape) 2. Modified example (example of wall hanging type)
[0012]
FIG. 1 illustrates an appearance of a display device according to an embodiment of the present
disclosure as viewed from the front. FIG. 2 shows an exploded perspective view of the main part
of the display device 1. The display device 1 is suitably used as, for example, a medium-sized to
large-sized television device, and has a configuration in which a flat plate-like main body portion
10 for image display is supported by a stand 20. Here, a case where the display device 1 is
mounted on a surface such as a floor, a shelf or a stand in a state where the stand 20 is attached
to the main body 10 and is used as a stationary type will be described as an example. However,
as described later, the display device 1 can be used as a wall hanging type in a state where the
stand 20 is removed from the main body portion 10.
[0013]
In the present specification, the longitudinal direction of the main body portion 10 is referred to
as Z direction, the lateral direction of the main surfaces (relatively wide surfaces of the respective
10-05-2019
4
surfaces) of the main body portion 10 is referred to as X direction, and the vertical direction is
referred to as Y direction.
[0014]
The main body unit 10 has, for example, a front plate 11 on the most front side (display side,
front).
For example, the liquid crystal panel 12, frame members (frames) 13A, 13B, 14, and 15, a light
source unit 16, and a speaker 17 are disposed on the back side (rear) of the front plate 11.
Although not shown, the rear surface of the main body 10 is covered by, for example, a rear
exterior member (rear cover).
[0015]
FIG. 3A shows a YZ cross-sectional configuration of the main body portion 10. In the main body
portion 10, the liquid crystal panel 12 is fixed (bonded) to the back side of the front plate 11 via
the adhesive layer 19A. A frame member 13A (second frame member) is fixed to the peripheral
portion of the liquid crystal panel 12 via the adhesive layer 19B. The frame member 14 (first
frame member) is fixed to the frame member 13A by, for example, screwing. The light source
unit 16 is assembled in a space surrounded by the frame members 13A and 14. The light source
unit 16 is screwed to the frame member 18 (third frame member), and is fixed to the main body
10 by fitting to the frame member 13A. The specific configuration of each part will be described
below. Here, the frame member 18 is provided as a separate member from the frame member 15
shown in FIG. However, the frame member 18 and the frame member 15 may be configured by
the same member (the frame member 15 may double as the frame member 18).
[0016]
The front plate 11 is made of, for example, a transparent plate such as glass or plastic. The
surface shape (XY planar shape) of two opposing main surfaces (first surface S1 and second
surface S2) of the front plate 11 is, for example, a rectangular shape. In the present embodiment,
substantially the entire area of the first surface S1 on the front side of the front plate 11 is
exposed, and the peripheral portion (front peripheral portion) of the first surface S1 is not
10-05-2019
5
covered by a so-called bezel or chassis. In addition, the front plate 11 has a region (region 11 a)
that protrudes to the left and right ends of the liquid crystal panel 12 when viewed from the
front. A speaker 17 is arranged corresponding to the area 11a. In the area 11 a of the front plate
11, circular openings are provided corresponding to the respective speaker elements 17 a.
[0017]
The liquid crystal panel 12 is, for example, a liquid crystal layer (not shown) sealed between two
glass substrates, and a polarizing plate is bonded to each surface of the light incident side and
the light output side. . The main components of these liquid crystal panels 12 are each
constituted by a thin plate-like or sheet-like flexible member made of glass or resin. Therefore,
the liquid crystal panel 12 has flexibility as a whole. Here, although the case where the display
body 120 includes the liquid crystal panel 12 and the light source unit 16 is taken as an
example, the display body 120 is not limited to this and an element having another display
function, such as an organic electroluminescent element. It may be comprised from the panel
containing.
[0018]
The light source unit 16 is a backlight unit that illuminates the liquid crystal panel 12. The light
source unit 16 includes, for example, an LED light source, a light guide plate, a reflecting
member, and an optical sheet. As an optical sheet, a diffusion plate, a diffusion sheet, a lens film,
a polarization separation sheet etc. are mentioned, for example. The light guide plate is for
guiding light from a light source consisting of, for example, an LED (Light Emitting Diode) or a
semiconductor laser to the liquid crystal panel 12 side, and for example, polycarbonate (PC) resin
or acrylic (for example, PMMA (for example, PMMA (for example) It mainly contains a
transparent thermoplastic resin such as polymethyl methacrylate) resin. The reflection member
is, for example, for returning the light emitted to the back side of the light guide plate to the light
guide plate, and is a plate-like or sheet-like member such as foamed PET (polyethylene
terephthalate), silver vapor deposition film, multilayer film reflection film, or white PET. It is. At
the back of the light source unit 16, a plate member 40 described later is provided.
[0019]
The frame members 13A, 13B, 14, 15, 18 are all metal frames or brackets fixed to the peripheral
10-05-2019
6
edge or outer edge of the display body 120. However, the frame member 15 may be made of
resin.
[0020]
The frame member 13A functions as, for example, a bracket for fixing and supporting the liquid
crystal panel 12, and is disposed so as to cover each of the four rectangular sides of the liquid
crystal panel 12. In this frame member 13A, for example, as shown in FIG. 3B, there are a
plurality of portions (portion 13a1 bent in an L shape) having a surface to be bonded to the
liquid crystal panel 12 and a surface to be fixed to the frame member 14. , Are spaced apart. In
other words, the frame member 13A has a plurality of notches at predetermined intervals. Such a
configuration can flexibly follow a curved shape described later.
[0021]
The frame member 13B functions as, for example, a bracket that supports the speaker 17. The
frame member 13B is provided, for example, along two rectangular short sides of the liquid
crystal panel 12 (at the left and right ends of the liquid crystal panel 12), and for example, a
circular opening corresponding to each element 17a of the speaker 17. have. The frame member
18 is a member for fixing the light source unit 16 to the liquid crystal panel 12, and is screwed to
the light source unit 16 (B2 in FIG. 3A).
[0022]
The frame member 14 is fixed to the liquid crystal panel 12 and the light source unit 16 via, for
example, the above-mentioned frame members 13A and 18, and along the long side along the
outer edge of the display body 120 (along the X direction ) Extended. In other words, the frame
member 14 is provided so as to sandwich the display body 120 from the upper side and the
lower side. The frame member 14 is obtained by, for example, processing the shape (XZ plane
shape) of the surface facing the display body 120 into, for example, a bow shape (a bow shape).
An example of the XZ plane shape of the frame member 14 is shown in FIG. Thus, the frame
member 14 has a gently curving bow shape. Although details will be described later, curved
shapes of the display body 120 and the front plate 11 are formed and held according to the bow
shape of the frame member 14. In addition, the curvature of the bow shape of the frame member
14 may be constant in the whole area, or may be different between the central portion and the
10-05-2019
7
left and right ends.
[0023]
The adhesive layer 19A includes, for example, a UV curable resin. Desirably, selective portions of
the adhesive layer 19A, specifically, the peripheral portion of the liquid crystal panel 12, include
microparticles such as beads having a diameter substantially the same as the thickness of the
adhesive layer 19A. In particular, such microparticles may be included in a region along the left
and right sides of the liquid crystal panel 12 (a region along the Y direction). It is because it can
suppress that the thickness of adhesion layer 19A becomes thin locally. Since the stress is easily
concentrated on the peripheral portion of the liquid crystal panel 12 due to the curved shape, the
thickness of the adhesive can be secured, and the occurrence of peeling can be prevented.
[0024]
The adhesive layer 19B contains an adhesive or an adhesive. It is desirable that the adhesive
layer 19B have flexibility. This is because propagation of stress from the outside to the liquid
crystal panel 12 can be reduced, and the occurrence of display unevenness can be suppressed.
[0025]
In the present embodiment, as shown in FIG. 1, at least the front side of the main body portion
10 has a curved shape. Specifically, the front plate 11 has a curved shape bent in an arc shape
along, for example, the X direction (first direction), and the back side (the side of the second
surface S2) of the front plate 11 In addition, the liquid crystal panel 12 of the display body 120
is pasted along the curved shape. The curved shape formed by the front plate 11 and the display
body 120 is a shape bent so that the first surface S1 is concave on the front side (the second
surface S2 is convex on the back side). This curved shape is formed and held by the frame
member 14. In other words, the curved shapes of the front plate 11 and the display body 120
follow the arc shape of the bow of the frame member 14. Thus, for example, as shown in FIG. 5,
when the display apparatus 1 is viewed from the front, the width in the vertical direction of the
display screen 110A gradually spreads from the central portion to the left and right ends. The
visual effects make it possible to create a sense of togetherness and immersion.
10-05-2019

[0026]
Further, this curved shape is preferably uniform in the Y direction. As compared with the case
where the curvature changes in the Y direction, it is difficult for the liquid crystal panel 12 to be
locally twisted, and the occurrence of damage to the liquid crystal panel 12 and display defects
can be suppressed.
[0027]
It is preferable that the stand 20 be provided, for example, on the left and right lower portions of
the main body portion 10. The reason is as follows. When the liquid crystal panel 12 is curved in
a backward direction, the stand 20 is hidden by the main body 10 because the positions of the
left and right ends come forward with respect to the position of the center of gravity of the main
body 10. As compared with the flat case, it is possible to make the forward protrusion of the
main body 10 of the stand 20 inconspicuous. Further, as described later, since the speakers are
disposed at the left and right ends of the main body portion 10, the speakers can be reliably
supported by the stands 20 laid under the left and right lower portions of the main body portion
10.
[0028]
The stand 20 can be provided not only at the left and right lower portions of the main body
portion 10 but also at the lower portion in the center of the main body portion 10. Further, when
the liquid crystal panel 12 is strongly curved or the like, the main body portion 10 can be made
to stand alone without the stand 20. The position, number, and shape of the stand 20 are not
particularly limited.
[0029]
FIG. 6A shows the configuration of the display device 1 shown in FIG. 1 as viewed from the back
side after removing the exterior member. FIG. 6B illustrates a perspective configuration in which
the plate member 40 and the frame member 50 are viewed from the back side. As described
above, in the main body portion 10, the reinforcing plate member 40 and the frame member 50
are disposed on the further back side of the display body 120. The plate member 40 and the
10-05-2019
9
frame member 50 are also shaped in accordance with the curved shape of the display body 120
described above. The configurations of the plate member 40 and the frame member 50 are an
example. Such a reinforcing member may or may not be provided. Further, only the plate
member 40 may be provided, and the frame member 50 may not be provided.
[0030]
The plate member 40 is formed of a flexible plate made of metal or resin. A plurality of (here,
three) frame members 50 are provided on the back surface of the plate member 40 so as to
extend in one direction (for example, the X direction). The plate member 40 is provided with a
boss (not shown) for fixing the frame member 50. The frame member 50 is provided with screw
holes 54 corresponding to the above-mentioned bosses and, if necessary, is provided with a VESA
(Video Electronics Standard Association) hole 55 for attaching a wall hanging bracket (described
later).
[0031]
Substrates 60 such as a source substrate, a timing controller substrate, and a balancer substrate
for controlling a backlight light source are mounted on the back of the plate member 40 (FIG.
6A). In addition, speakers 17 are disposed in regions corresponding to the left and right ends of
the liquid crystal panel 12. By arranging the speakers 17 at the left and right ends of the main
body portion 10, the image and the sound are integrated without visual separation, and together
with the visual effect of perspective by the curved shape described above, a sense of unity and
immersion It becomes possible to strengthen.
[0032]
It is preferable that the speakers 17 be arranged to protrude to the left and right of the liquid
crystal panel 12 and to the rear of the plate member 40. As a result, the capacity of the speaker
17 is secured, and the output can be increased and the sound quality can be improved. As shown
in FIG. 1, the speaker 17 is a speaker box (speaker system) configured of a plurality of speaker
elements 17a, and is preferably configured of, for example, a four-channel surround speaker.
This is because the sense of unity and immersiveness can be further intensified by the visual
effect by the above-mentioned curved shape and the sound spreading to the front, rear, left and
right. The specific configuration of the speaker 17 will be described later.
10-05-2019

[0033]
(Assembly Method) The curved shapes of the front plate 11 and the display body 120 in the
display device 1 can be formed, for example, as follows. 7A to 8B are schematic cross-sectional
views for explaining the method of assembling the display device 1.
[0034]
First, the front plate 11 made of glass or the like and the liquid crystal panel 12 are prepared.
Then, as shown in FIG. 7A, the liquid crystal panel 12 is bonded to a predetermined region of the
second surface S2 of the front plate 11 via the adhesive layer 19A.
[0035]
Subsequently, as shown in FIG. 7B, the frame member 13A and the frame member 13B are
bonded to the peripheral edge portion of the liquid crystal panel 12 via the adhesive layer 19B.
Thus, the liquid crystal panel 12 can be fixed to the frame member 13A in a state before bending
(flat state).
[0036]
After that, as shown in FIG. 7C, the frame member 14 processed into an arch shape is fixed to the
frame member 13A by, for example, screwing (arrow B1 in FIG. 7C). Thereby, along the X
direction, the front plate 11 and the liquid crystal panel 12 are bent in an arc according to the
bow shape of the frame member 14 and held in a curved shape.
[0037]
Next, as shown in FIG. 8A, the light source unit 16 as a backlight unit is assembled in the space
surrounded by the frame members 13 a and 14 on the back side of the liquid crystal panel 12.
10-05-2019
11
Subsequently, as shown in FIG. 8B, the frame member 18 is screwed to the light source unit 16
(arrow B2 in FIG. 8B), and by fitting the frame member 13A and 14 together, the light source
unit 16 is liquid crystal panel Fix it on the back side of 12. Further, as a result, the light source
unit 16 is also fixed in a state of being bent in an arc shape following the curved shape of the
liquid crystal panel 12. Thus, the front plate 11 and the display body 120 are integrally formed
in a curved shape. A reinforcing member such as the above-described plate member 40 may be
attached to the back side of the light source unit 16.
[0038]
Thereafter, the speaker 17 and the substrates 60 are mounted on the back side of the light
source unit 16 via the plate member 40 and the like. Thereby, the main body 10 can be
manufactured. Finally, the back surface of the main body portion 10 is covered with a rear
exterior member (not shown), and the stand 20 is attached to the left and right lower portions of
the main body portion 10. Thus, the display device 1 shown in FIG. 1 is completed.
[0039]
(Detailed Configuration of Speaker) FIG. 9A shows an enlarged configuration of the speaker
element 17a together with the appearance of the front side of the main body 10. As shown in
FIG. Thus, the speaker element 17a has, for example, the diaphragm 17a1 and the decorative
component 17a2 facing the opening of the front plate 11. That is, in the speaker element 17a,
the diaphragm 17a1 and the decorative component 17a2 are elements constituting a design.
[0040]
FIG. 9B is a cross-sectional view of essential parts for describing the internal structure of the
speaker element 17a. FIG. 9C is a perspective view showing the appearance of the speaker
element 17a. FIG. 10 shows an example of the decorative part 17a2. The speaker element 17a
mounts a speaker unit 17a5 including a sound generation source, and is fixed to and supported
by the front plate 11 so as to sandwich the decorative part 17a2.
[0041]
10-05-2019
12
The decorative component 17a2 is a component including an inclined surface in the shape of an
inverted truncated cone formed so as to surround the diaphragm 17a1. In the inclined surface of
this decorative part 17a2, when the width seen from the front is d1, the height is d2, and the
inclination angle is θ, the width d1 is to be minimized from the viewpoint of design. .
[0042]
The plate member 17a4 is, for example, a flat plate. The plate member 17a4 is drawn for
reinforcement. In other words, the plate member 17a4 is formed in a concave shape as a whole,
and its edge (edge 170) is raised on one side.
[0043]
Here, generally, as shown in FIGS. 11A and 11B, the edge (edge 101a) of the plate member 101
supporting the diaphragm 17a1 and the speaker unit 17a5 is the front in the Z direction (front
side, display side) Has been launched. When the decorative component 17a2 is attached to the
front of the plate member 101, the gap between the plate member 101 and the decorative
component 17a2 tends to be large in order to secure a space corresponding to the height of the
edge 101a. As a result, the sound is easily kicked by the inclined surface of the decorative part
17a2.
[0044]
On the other hand, the height d2 of the decorative component 17a2 depends on the structural
thickness from the front plate 11 to the plate member 17a4. For this reason, when the width d1
is narrowed by pursuing the design, the height d2 has a restriction, and as a result, the
inclination angle θ becomes large (the inclination becomes steep), and the sound is not easily
spread. It will
[0045]
In the present embodiment, as shown in FIGS. 12A and 12B, the edge 170 of the plate member
10-05-2019
13
17a4 is raised in the Z direction (rear side, opposite to the display side). Therefore, when the
decorative component 17a2 is attached to the front of the plate member 17a4, there is no need
to secure a space for the edge 170 between the plate member 17a4 and the decorative
component 17a2. That is, the gap between the plate member 17a4 and the decorative
component 17a2 can be narrowed, and the sound can be easily spread on the inclined surface of
the decorative component 17a2. In addition, the narrowing of the gap increases the degree of
freedom of the inclination angle θ of the decorative component 17a2. As a result, the width d1
can be narrowed while suppressing the kicking of the sound, which is advantageous for design
improvement. In addition, since the degree of freedom of the inclination angle θ is increased, the
speaker element 17a can be installed on the curved surface of the front plate 11 while adjusting
the inclination angle θ and the width d1 to desired values. Become. Thus, since the degree of
freedom of the speaker design is increased, for example, the design can be enhanced while
suppressing the influence on the sound.
[0046]
In the display device 1 as described above, the front plate 11 has a curved shape bent in an arc
shape along one direction (X direction). The display body 120 is bonded to the back surface side
(the second surface S2 side) of the front plate 11 according to the curved shape. In such a
configuration, the light from the light source unit 16 is transmitted through the liquid crystal
panel 12 to perform predetermined image display. Because of the above curved shape, as shown
in FIG. 5, the width of the display screen 110A viewed from the front can be expanded gradually
from the central portion to the left and right ends. Immersive feeling is born, and it becomes
possible to realize realistic visual display.
[0047]
Further, in the present embodiment, the front plate 11 is disposed so as to expose substantially
the entire area of the first surface S1. That is, the front peripheral edge of the display device 1 is
not covered by a frame-shaped member such as a bezel. This improves the designability.
[0048]
In addition, since the curved shape of the display body 120 and the front plate 11 is formed and
supported by using the frame member 14 processed into the bow shape, the desired curved
shape can be easily maintained, and Peeling with the front plate 11 can be suppressed.
10-05-2019

[0049]
Here, in FIG. 13, as a comparative example, a frame member 103 (sheet metal) is directly
attached to the peripheral portion of the front plate 11 as an example of a structure in which the
display body 120 is bonded to the second surface S2 side of the front plate 11. It shows about
the principal part structure at the time of adhering and fixing.
As described above, when the frame member 103 is fixed to the front plate 11, the curved shape
(curvature) is fixed at both ends of the front plate 11 as schematically shown in FIG. A force
(arrow X1 in FIG. 14) is easily applied to both ends in the direction opposite to the bending
direction (the liquid crystal panel 12 tries to return to a flat shape). As a result, the liquid crystal
panel 12 is easily peeled off from the front plate 11.
[0050]
On the other hand, in the present embodiment, since the bow-shaped frame member 14 is fixed
to the peripheral portion of the liquid crystal panel 12 via the frame member 13A (FIG. 3A), as
schematically shown in FIG. The curved shape (curvature) is fixed at the peripheral portion of the
liquid crystal panel 12. Therefore, a force (arrow X2 in FIG. 14) is easily applied to both ends of
the front plate 11 in the direction opposite to the bending direction (the front plate 11 tries to
return to a flat shape). That is, in the present embodiment, a force is more easily applied in the
direction in which the front plate 11 and the liquid crystal panel 12 face each other. As a result,
the liquid crystal panel 12 is less likely to come off from the front plate 11.
[0051]
In addition, since the speakers 17 are disposed on the left and right of the liquid crystal panel 12,
the image and the sound are integrated without visual separation, and together with the visual
effect by the curved shape of the liquid crystal panel 12 described above Immersion can be
further enhanced. In particular, in the present embodiment, as shown in FIGS. 12A and 12B, the
edge 170 of the plate member 17a4 is raised rearward in the Z direction (rear side, opposite to
the display side). As a result, the gap between the plate member 17a4 and the decorative
component 17a2 can be narrowed, and the degree of freedom in speaker design can be
increased. Moreover, it becomes easy to install also on the curved surface of the front plate 11.

As described above, in the present embodiment, substantially the entire area of the first surface
S1 of the front plate 11 having a curved shape bent in an arc shape along one direction is
exposed and disposed on the display side. The display body 120 is attached to the side of the
surface S2 following the curved shape. This makes it possible to realize highly realistic and
realistic image display.

<Modification> Next, a modification of the display device 1 of the above embodiment will be
described. Below, about the component similar to the said embodiment, the same code | symbol
is attached | subjected and description is abbreviate | omitted suitably.
[0054]
In the above embodiment, the display apparatus 1 has been described by way of an example of a
stationary type (one having the stand 20) used in a state where the display apparatus 1 is placed
on a table or the like. As in the present modification, it may be used while being fixed to a wall or
the like. FIG. 16 shows an example of a wall-mounted display device. 17A and 17B are side views
of the state in which the main body 10 is attached to the wall S3. Thus, in the present
modification, the fixture 21 is attached (attachable) to the back side of the main body 10 instead
of the stand 20.
[0055]
The fixture 21 includes, for example, a support member 21A as a bracket for fixing and
supporting the main body portion 10, and a support member 21B as a base plate fixed to a wall.
In addition, the structure of the fixing tool 21 demonstrated here is an example, It is not
necessarily limited to this structure. Furthermore, it may have other members, and the shape of
each member may be different.

[0056]
The support members 21A and 21B are fixed to, for example, a VESA hole 55 provided in the
frame member 50 on the back side of the main body portion 10 by a screw. The support member
21A has, for example, an arm 21a1, and as shown in FIGS. 17A and 17B, this arm 21a1 can be
used to make stepwise adjustment of the installation angle. In FIG. 17A, the arm 21a1 is folded,
and the main body 10 is attached substantially perpendicularly to the wall surface. In FIG. 17B,
the arm 21a1 is expanded, and the main body 10 is attached in a state of being inclined with
respect to the wall surface.
[0057]
As mentioned above, although an embodiment and a modification were mentioned and explained,
the present disclosure is not limited to the above-mentioned embodiment etc., and various
modification is possible. For example, although the case where the front plate 11 and the display
body 120 are curved over the entire area in the X direction has been described in the abovedescribed embodiment and the like, the entire area may not necessarily be curved. It may be
curved in part in the X direction (for example, the central part is flat, and the left and right parts
are curved). Further, the curvature of the curved portion does not have to be constant, and may
be configured to change the curvature from the central portion to the left and right ends, or the
curvature may be locally different. For example, it is desirable that an appropriate curvature be
set according to the aspect ratio of the display screen, the diagonal size, and the like.
[0058]
Moreover, although the thing containing the liquid crystal panel 12 and the light source part 16
was illustrated as the display body 120 in the said embodiment etc., the display body of this
indication is not limited to what used a liquid crystal panel, Other displays A structure having a
function may be used. For example, an organic EL (Electroluminescence) panel may be used in
place of the liquid crystal panel 12 and the light source unit 16.
[0059]
Furthermore, for example, the material, thickness, and the like of each layer described in the
above embodiment are not limited, and other materials and thicknesses may be used.
