DESCRIPTION OF EMBODIMENTS

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the present disclosure is not limited to the following embodiments. In addition, the embodiments can be arbitrarily combined in a range in which the processing contents do not contradict each other. Also, in the following embodiments, the same reference sign is assigned to the same parts and an overlapped description thereof is omitted.

Although expressions such as “constant”, “orthogonal”, “vertical”, or “parallel” may be used in the embodiments described below, these expressions do not need to be strictly “constant”, “orthogonal”, “vertical”, or “parallel”. That is, it is assumed that each of the expressions described above allows deviation in manufacturing accuracy, installation accuracy, and the like, for example.

Conventionally, a large-screen display device (hereinafter, also referred to as a video wall) that forms one display screen by an arrangement of a plurality of display units in a matrix has been known.

Such a video wall is used, for example, for an advertisement display in a town, an exhibition, and information provision to spectators in a sports facility or the like. In addition, the video wall is configured by, for example, an arrangement and assembly of a plurality of display units in a frame.

On the other hand, in the above-described related art, while a video wall having a flat screen can be assembled relatively easily, it is very difficult to accurately assemble a screen having a desired curvature.

Thus, it is expected to realize a technology capable of overcoming the above-described problems and easily forming a large screen having a desired curvature in a video wall.

Display System

First, a configuration of a display system S according to the embodiment will be described with reference to FIG. 1. FIG. 1 is a block diagram illustrating an example of the configuration of the display system S according to the embodiment of the present disclosure.

As illustrated in FIG. 1, the display system S according to the embodiment includes a video wall 1, a video server 11, a display control device 12, and an operation terminal 13. The video wall 1 according to the embodiment is an example of a display device, and is also referred to as multiple displays, a tiling display, or the like.

The video wall 1 according to the embodiment includes a plurality of display units 2-1 to 2-n. Details of the video wall 1 will be described later.

The video server 11 stores various kinds of video data. Note that the video data stored in the video server 11 may be a moving image or a still image.

The display control device 12 divides the video data acquired from the video server 11 and performs distribution thereof to the plurality of display units 2-1 to 2-n provided on the video wall 1. Pieces of divided video based on the divided video data are respectively displayed on the plurality of display units 2-1 to 2-n.

Then, the whole video based on the video data is formed on the video wall 1 by a set of the pieces of divided video respectively displayed on the plurality of display units 2-1 to 2-n.

The operation terminal 13 is, for example, a personal computer (PC), and operates the display control device 12. The operation terminal 13 designates, for example, video data acquired by the display control device 12 from the video server 11 and displayed on the video wall 1.

Note that the video data transmitted from the operation terminal 13 to the display control device 12 may be displayed on the video wall 1 in the present disclosure.

Video Wall

Next, an outline of the video wall 1 according to the embodiment will be described with reference to FIG. 2. FIG. 2 is a perspective view illustrating an example of an outline of the video wall 1 according to the embodiment of the present disclosure.

As illustrated in FIG. 2, the video wall 1 includes a plurality of display units 2 and a frame system 3. Each of the display units 2 is a unit (module) including a display panel on which a video is displayed by electric control.

The display unit 2 includes a display panel including a pixel array unit, and a circuit unit provided with a circuit to drive the pixel array unit, a power supply, and the like. Note that the configuration illustrated in FIG. 2 is an example, and the number, a shape, an arrangement, and the like of the display units 2 are not limited thereto.

In the pixel array unit included in the display panel of the display unit 2, for example, a plurality of pixels is arranged in a matrix. In one pixel, for example, light emitting elements that emit light of three primary colors of red (R), green (G), and blue (B) is arranged. Examples of such light emitting elements include light emitting diodes (LED).

The display panel is, for example, a glass epoxy substrate on which an LED is mounted. In this pixel array unit, each pixel is pulse-driven on the basis of a video signal input from the display control device 12 (see FIG. 2), whereby luminance of each LED is adjusted and a video is displayed. Note that the display panel of the display unit 2 may be a liquid crystal panel, an organic electro-luminescence (EL) panel, or the like.

The video wall 1 according to the embodiment includes a display unit group 10 in which a plurality of the display units 2 is arranged in a matrix and which included in one display screen. The frame system 3 is a structure that supports the plurality of display units 2 (that is, the display unit group 10).

Frame System

Next, details of the frame system 3 according to the embodiment will be described with reference to FIG. 3 to FIG. 14 in addition to FIG. 2 described above. FIG. 3 is a side view illustrating an example of a configuration of the video wall 1 according to the embodiment of the present disclosure, and FIG. 4 is an enlarged top view illustrating an example of a configuration of the frame system 3 according to the embodiment of the present disclosure.

Note that although a plurality of attachment members 8 (see FIG. 3) and the plurality of display units 2 (see FIG. 3) are not illustrated in FIG. 4 to make understanding easier, these members are arranged on a left side of FIG. 4.

As illustrated in FIG. 2 to FIG. 4, the frame system 3 includes a plurality of back frames 4, a plurality of base frames 5, a plurality of first coupling members 6, a plurality of second coupling members 7, and a plurality of attachment members 8.

As illustrated in FIG. 3, each of the back frames 4 is arranged on a floor F in a state of rising vertically to the floor F. In addition, as illustrated in FIG. 2 and the like, the plurality of back frames 4 is arranged in a line.

Furthermore, as illustrated in FIG. 3, side portions 4a of the back frames 4 directed in the same direction can hold peripheral edge portions of the back surfaces 2a (that is, opposite surface of a display surface) of the display units 2 via the attachment members 8. In addition, the plurality of attachment members 8 is provided on the side portion 4a of one back frame 4.

As illustrated in FIG. 2, the base frames 5 couples the back frames 4, which are adjacent to each other, in a direction parallel to the floor F (see FIG. 3). In addition, as illustrated in FIG. 3, the base frames 5 are arranged at bottom portions on a side of holding the display units 2 (that is, the side portions 4a) in the back frames 4.

As illustrated in FIG. 4, the first coupling members 6 couple the adjacent back frames 4 in the direction parallel to the floor F (see FIG. 3). In addition, as illustrated in FIG. 3, the first coupling members 6 are arranged at bottom portions on a side opposite to the side of holding the display units 2 in the back frames 4.

Furthermore, the second coupling members 7 also couple the adjacent back frames 4 in the direction parallel to the floor F. The second coupling members 7 are arranged between the base frames 5 and the first coupling members 6 in a planar view as illustrated in FIG. 4, and are arranged at positions farther from the floor F than the first coupling members 6 (that is, positions higher than the first coupling members 6) as illustrated in FIG. 3.

For the back frames 4, the base frames 5, the first coupling members 6, and the second coupling members 7, it is desirable to use a material that is light and excellent in heat dissipation, such as aluminum (Al) alone or an alloy containing aluminum.

Here, in the embodiment, as illustrated in FIG. 4, one back frame 4 and a pair of the base frames 5 coupled to the back frame 4 include an angle adjustment unit 20 that adjusts an angle between the pair of base frames 5. Details of the angle adjustment unit 20 will be described in the following.

FIG. 5 is a top view illustrating an example of a configuration of the angle adjustment unit 20 according to the embodiment of the present disclosure, and is a view illustrating a first angle adjustment unit 30, which is provided in each of the back frames 4, in the angle adjustment unit 20.

The first angle adjustment unit 30 includes a pair of screw hole groups 31. The pair of screw hole groups 31 corresponds to through hole groups 41 (see FIG. 6) of second angle adjustment units 40 (see FIG. 6) respectively provided in the pair of base frames 5 (see FIG. 4). A plurality of screw holes 32 is formed in the screw hole groups 31.

In addition, the screw holes 32 of different types are formed in the screw hole groups 31 for each angle (also referred to as an “attachment angle” in the present disclosure) between the pair of base frames 5 adjusted by the angle adjustment unit 20. For example, in the angle adjustment unit 20 of the present disclosure, four types of attachment angles of 0(°), 3(°), 5(°), and 7(°) are set in advance.

In this case, each of the screw hole groups 31 includes a screw hole 32a corresponding to the attachment angle of 0(°), a screw hole 32b corresponding to the attachment angle of 3(°), a screw hole 32c corresponding to the attachment angle of 5(°), and a screw hole 32d corresponding to the attachment angle of 7(°). In addition, the plurality of (two in the drawing) screw holes 32a to 32d is formed in each of the screw hole groups 31.

FIG. 6 is a top view illustrating an example of the configuration of the angle adjustment unit 20 according to the embodiment of the present disclosure, and is a view illustrating the second angle adjustment unit 40 provided in the base frame 5 in the angle adjustment unit 20.

The second angle adjustment unit 40 includes the through hole group 41. A plurality of through holes 42 is formed in the through hole group 41. In addition, the through holes 42 of different types are formed in the through hole group 41 for each of the attachment angles adjusted by the angle adjustment unit 20.

For example, the through hole group 41 of the present disclosure includes a through hole 42a corresponding to the attachment angle of 0(°), a through hole 42b corresponding to the attachment angle of 3(°), a through hole 42c corresponding to the attachment angle of 5(°), and a through hole 42d corresponding to the attachment angle of 7(°). In addition, the plurality of (two in the drawing) through holes 42a to 42d is formed in the through hole group 41.

FIG. 7 is a top view illustrating an example of the configuration of the angle adjustment unit 20 of a case where the attachment angle is 0(°). As illustrated in FIG. 7, in the present disclosure, for example, the base frames 5 are attached to the back frames 4 in such a manner that the second angle adjustment units 40 (see FIG. 6) of the base frames 5 cover the first angle adjustment units 30 (see FIG. 5) of the back frames 4.

Then, during this attachment work, the base frames 5 are attached to the back frames 4 in such a manner that the screw holes 32 and the through holes 42 corresponding to the desired attachment angle overlap each other, and bolts (not illustrated) are screwed into the screw holes 32 through the through holes 42.

For example, in the example of FIG. 7, since the desired attachment angle is 0(°), the base frames 5 are attached to the back frames 4 and the bolts are further attached in such a manner that the screw holes 32a and the through holes 42a corresponding to the attachment angle 0(°) overlap each other.

In such a manner, by attaching the pair of base frames 5 at the attachment angle 0(°), it is possible to set an angle between the back frames 4 coupled to each other via the base frames 5 to 0(°).

Thus, according to the embodiment, as illustrated in FIG. 8, since all the back frames 4 are arranged in parallel, the video wall 1 in which the display screen including the plurality of display units 2 is flat can be configured. FIG. 8 is a top view illustrating an example of the configurations of the video wall 1 and the frame system 3 of a case where the attachment angle is 0(°).

FIG. 9 is a top view illustrating an example of the configuration of the angle adjustment unit 20 of a case where the attachment angle is 7(°). In the example of FIG. 9, since the desired attachment angle is 7(°), the base frames 5 are attached to the back frames 4 and the bolts (not illustrated) are further attached in such a manner that the screw holes 32d and the through holes 42d corresponding to the attachment angle 7(°) overlap each other.

In such a manner, by attaching the pair of base frames 5 to each other at the attachment angle 7(°), it is possible to set the angle between the back frames 4 coupled to each other via the base frames 5 to 7(°).

Thus, according to the embodiment, as illustrated in FIG. 10, since the parallel back frames 4 are arranged in a manner of being inclined by 7(°), it is possible to configure the video wall 1 in which the display screen including the plurality of display units 2 is an arc having a small radius of curvature. FIG. 10 is a top view illustrating an example of the configurations of the video wall 1 and the frame system 3 of a case where the attachment angle is 7(°).

Note that although not illustrated, when the base frames 5 are attached to the back frames 4 in such a manner that the screw holes 32b (see FIG. 5) and the through holes 42b (see FIG. 6) corresponding to the attachment angle 3(°) overlap with each other, an angle between the pair of base frames 5 becomes 3(°).

In such a manner, by attaching the pair of base frames 5 to each other at the attachment angle 3(°), it is possible to set the angle between the back frames 4 coupled to each other via the base frames 5 to 3(°).

Thus, according to the embodiment, as illustrated in FIG. 11, since the parallel back frames 4 are arranged in a manner of being inclined by 3(°), it is possible to configure the video wall 1 in which the display screen including the plurality of display units 2 is an arc having a large radius of curvature. FIG. 11 is a top view illustrating an example of the configurations of the video wall 1 and the frame system 3 of a case where the attachment angle is 3(°).

In addition, although not illustrated, when the base frames 5 are attached to the back frames 4 in such a manner that the screw holes 32c (see FIG. 5) and the through holes 42c (see FIG. 6) corresponding to the attachment angle 5 (') overlap with each other, the angle between the pair of base frames 5 becomes 5(°).

In such a manner, by attaching the pair of base frames 5 to each other at the attachment angle 5(°), the angle between the back frames 4 coupled to each other via the base frames 5 can be set to 5(°).

Thus, according to the embodiment, as illustrated in FIG. 12, since the parallel back frames 4 are arranged in a manner of being inclined by 5(°), it is possible to configure the video wall 1 in which the display screen including the plurality of display units 2 is an arc having a relatively small radius of curvature. FIG. 12 is a top view illustrating an example of the configurations of the video wall 1 and the frame system 3 of a case where the attachment angle is 5(°).

As described above, in the embodiment, by adjusting the attachment angle between the pair of base frames 5 to a desired angle by the angle adjustment unit 20, the angle between the adjacent back frames 4 can be easily adjusted to the desired angle.

Thus, according to the embodiment, since the angle between the display units 2 adjacent in a lateral direction can be easily adjusted to a desired angle, it is possible to easily form a large screen having a desired curvature in the video wall 1.

In the embodiment, the angle adjustment unit 20 may include the plurality of through holes 42 formed in the base frames 5 and respectively corresponding to the plurality of attachment angles, and the plurality of screw holes 32 formed in the back frames 4 and respectively corresponding to the plurality of attachment angles.

Thus, the attachment angle between the pair of base frames 5 can be easily adjusted to a desired angle by the angle adjustment unit 20.

Note that in the embodiment, a preset attachment angle may be marked in the vicinity of the through holes 42 in the base frames 5 and in the vicinity of the screw holes 32 in the back frames 4. Accordingly, it is possible to prevent the base frames 5 from being attached to the back frames 4 at an attachment angle different from the desired angle.

In addition, the angle adjustment unit 20 may be arranged at the bottom portion on the side of holding the display units 2 in each of the back frames 4 in the embodiment. Thus, the angle adjustment unit 20 can be arranged close to the display units 2, whereby the angle between the adjacent display units 2 can be adjusted accurately.

Furthermore, since the angle adjustment unit 20 is arranged at the bottom portion on the side of holding the display units 2 in each of the back frames 4, the angle adjustment unit 20 can be prevented from interfering with the display screen formed by the plurality of display units 2.

FIG. 13 is a top view illustrating an example of the configuration of the attachment member 8 corresponding to the attachment angle 0(°), and FIG. 14 is a top view illustrating an example of the configuration of the attachment member 8 corresponding to the attachment angle 7(°).

As illustrated in FIG. 13 and FIG. 14, a dedicated attachment member 8 is used according to the desired attachment angle in the embodiment. Specifically, the attachment member 8 according to the embodiment has a dog-bone shape in a planar view, and has an attachment surface 8c at a distal end portion 8b on a side opposite to a proximal end portion 8a abutting on a side portion 4a of each of the back frames 4.

Furthermore, the attachment surface 8c has a first attachment surface 8c1 in contact with the back surface 2a of one of the display units 2 and a second attachment surface 8c2 in contact with the back surface 2a of the other display unit 2. Then, in the attachment member 8, an angle between the first attachment surface 8c1 and the second attachment surface 8c2 is set to be the same angle as the desired attachment angle.

For example, in the example of FIG. 13, since the attachment member 8 corresponds to the attachment angle 0(°), the angle between the first attachment surface 8c1 and the second attachment surface 8c2 is set to 0(°). In addition, in the example of FIG. 14, since the attachment member 8 corresponds to the attachment angle 7(°), the angle between the first attachment surface 8c1 and the second attachment surface 8c2 is set to 7(°).

As described above, in the embodiment, since the attachment surface 8c having the angle corresponding to the desired attachment angle is provided on the attachment member 8, even in a case where the display screen has a desired curvature, a contact area between the attachment member 8 and the display units 2 can be increased.

Thus, according to the embodiment, even in a case where the display screen has the desired curvature, the display units 2 can be firmly attached to the back frames 4.

In addition, as illustrated in the side view of FIG. 3 and the plan view of FIG. 13, the attachment member 8 may be capable of holding corner portions of the display units 2 in the embodiment. As a result, since the corner portions of four of the display units 2 can be simultaneously held by the one attachment member 8, the number of attachment members 8 can be reduced.

Thus, according to the embodiment, a manufacturing cost of the video wall 1 can be reduced.

In the embodiment, as illustrated in FIG. 3 and FIG. 4, the frame system 3 may include the first coupling member 6 that is arranged at the bottom portion on the side opposite to the side of holding the display unit 2 in each of the back frames 4, and that couples the adjacent back frames 4 to each other in the direction parallel to the floor F.

As a result, the adjacent back frames 4 can be more firmly coupled to each other as compared with a case where the adjacent back frames 4 are coupled to each other only by the base frame 5. Thus according to the embodiment, it is possible to control collapse of a shape of the frame system 3 due to vibration of the floor F or the like.

In addition, in the embodiment, a dedicated first coupling member 6 may be used according to the desired attachment angle. Specifically, a length of the first coupling member 6 according to the embodiment may be gradually increased as the desired attachment angle increases.

Accordingly, even in a case where the display screen has the desired curvature, the first coupling member 6 can be attached to a predetermined position (such as the bottom portion on the side opposite to the side of holding the display unit 2 in each of the back frames 4) without any problem.

Thus, according to the embodiment, it is possible to control the collapse of the shape of the frame system 3 due to the vibration of the floor For the like even in a case where the display screen has the desired curvature.

In the embodiment, the frame system 3 may further include the second coupling member 7 that is arranged at the position farther from the floor F than the first coupling member 6 and couples the adjacent back frames 4 to each other in the direction parallel to the floor F.

As a result, the adjacent back frames 4 can be more firmly coupled to each other as compared with a case where the adjacent back frames 4 are coupled to each other only by the base frame 5 and the first coupling member 6. Thus, according to the embodiment, it is possible to further control the collapse of the shape of the frame system 3 due to the vibration of the floor For the like.

In addition, as illustrated in FIG. 4, one second coupling member 7 may be arranged across three or more back frames 4 in the embodiment. Accordingly, since the three or more back frames 4 can be simultaneously held by the one second coupling member 7, the number of second coupling members 7 can be reduced.

Thus, according to the embodiment, a manufacturing cost of the video wall 1 can be reduced.
