[0007] Hereinafter, each embodiment of the present disclosure will be described with reference to the accompanying drawings. Note that the present disclosure is not limited by the embodiments shown below. Also, each embodiment can be appropriately combined as long as the processing contents do not conflict. In addition, the same parts in the following embodiments are denoted by the same reference numerals, and overlapping descriptions are omitted.

[0008] In addition, in the embodiments shown below, expressions such as "constant", "orthogonal", "perpendicular", or "parallel" may be used, but these expressions do not necessarily require strict "constant", "orthogonal", "perpendicular", or "parallel". That is, each of the above expressions is assumed to allow deviations such as manufacturing accuracy and installation accuracy.

[0009] Conventionally, a large-screen display device (hereinafter also referred to as a video wall) that constitutes one display screen by arranging a plurality of display units in a matrix has been known.

[0010] Such a video wall is used, for example, for advertising displays in the street, information provision to spectators at exhibitions, sports facilities, etc. Also, this video wall is configured, for example, by arranging and assembling a plurality of display units in a frame.

[0011] On the other hand, in the above prior art, a video wall having a flat screen can be assembled relatively easily, while it was very difficult to accurately assemble a screen having a desired curvature.

[0012] Therefore, it is expected to realize a technology that overcomes the above problems and can easily form a large screen having a desired curvature in a video wall.

[0013] [Display System] First, the configuration of the display system S according to the embodiment will be described with reference to FIG. 1. FIG. 1 is a block diagram showing an example of the configuration of the display system S according to the embodiment of the present disclosure.

[0014] As shown 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 a multi-display or a tiling display.

[0015] The video wall 1 according to the embodiment has a plurality of display units 2-1 to 2-n. Details of such a video wall 1 will be described later.

[0016] The video server 11 stores various video data. Note that the video data stored in the video server 11 may be a moving image or a still image.

[0017] The display control device 12 divides the video data acquired from the video server 11 and distributes it to the plurality of display units 2-1 to 2-n provided on the video wall 1. A divided video based on the divided video data is displayed on each of the plurality of display units 2-1 to 2-n.

[0018] Then, an overall video based on the video data is formed on the video wall 1 by the collection of the divided videos displayed on each of the plurality of display units 2-1 to 2-n.

[0019] The operation terminal 13 is, for example, a PC (Personal Computer), and operates the display control device 12. The operation terminal 13, for example, designates the video data acquired by the display control device 12 from the video server 11 and displayed on the video wall 1.

[0020] Note that in the present disclosure, the video data transmitted from the operation terminal 13 to the display control device 12 may be displayed on the video wall 1.

[0021] [Video Wall] Next, an overview of the video wall 1 according to the embodiment will be described with reference to FIG. 2. FIG. 2 is a perspective view showing an example of an overview of the video wall 1 according to the embodiment of the present disclosure.

[0022] As shown in Figure 2, the video wall 1 comprises a plurality of display units 2 and a frame system 3. Each display unit 2 is a unit (module) that includes a display panel on which images are displayed by electrical control.

[0023] The display unit 2 includes a display panel containing a pixel array and a circuit unit equipped with circuits for driving the pixel array and a power supply. Note that the configuration shown in Figure 2 is an example, and the number, shape, and arrangement of the display units 2 are not limited to this.

[0024] The pixel array portion included in the display panel of the display unit 2 contains, for example, multiple pixels arranged in a matrix. Within each pixel, for example, light-emitting elements that emit light of the three primary colors, red (R), green (G), and blue (B), are arranged. Examples of such light-emitting elements include light-emitting diodes (LEDs).

[0025] The display panel is, for example, a glass epoxy substrate on which LEDs are mounted. In this pixel array section, each pixel is pulse-driven based on the video signal input from the display control device 12 (see Figure 2), thereby adjusting the brightness of each LED and displaying the image. The display panel of the display unit 2 may also be a liquid crystal panel or an organic EL (Electro-Luminescence) panel, etc.

[0026] The video wall 1 according to this embodiment includes a group of display units 10 in which a plurality of display units 2 are arranged in a matrix to form a single display screen. The frame system 3 is a structure that supports the plurality of display units 2 (i.e., the group of display units 10).

[0027] [Frame System] Next, the details of the frame system 3 according to the embodiment will be described with reference to Figures 3 to 14, in addition to Figure 2 which has been described so far. Figure 3 is a side view showing an example of the configuration of the video wall 1 according to the embodiment of this disclosure, and Figure 4 is an enlarged top view showing an example of the configuration of the frame system 3 according to the embodiment of this disclosure.

[0028] Note that in Figure 4, for the sake of ease of understanding, the multiple mounting members 8 (see Figure 3) and multiple display units 2 (see Figure 3) are not shown, but these members are located on the left side of Figure 4.

[0029] As shown in Figures 2 to 4, the frame system 3 comprises a plurality of back frames 4, a plurality of base frames 5, a plurality of first connecting members 6, a plurality of second connecting members 7, and a plurality of mounting members 8.

[0030] As shown in Figure 3, the back frame 4 is positioned on the floor surface F, standing perpendicular to it. Also, as shown in Figure 2 and other figures, multiple back frames 4 are arranged in a line.

[0031] Furthermore, as shown in Figure 3, the sides 4a of each back frame 4 facing the same direction can hold the peripheral edge of the back surface 2a of the display unit 2 (i.e., the opposite side of the display surface) via mounting members 8. In addition, multiple mounting members 8 are provided on the side 4a of one back frame 4.

[0032] As shown in Figure 2, the base frame 5 connects adjacent back frames 4 in a direction parallel to the floor surface F (see Figure 3). Also, as shown in Figure 3, the base frame 5 is positioned at the bottom of the side of the back frame 4 that holds the display unit 2 (i.e., the side portion 4a).

[0033] As shown in Figure 4, the first connecting member 6 connects adjacent back frames 4 in a direction parallel to the floor surface F (see Figure 3). Also, as shown in Figure 3, the first connecting member 6 is positioned at the bottom of the back frame 4 on the side opposite to the side that holds the display unit 2.

[0034] Furthermore, the second connecting member 7 also connects adjacent back frames 4 in a direction parallel to the floor surface F. As shown in Figure 4, the second connecting member 7 is positioned between the base frame 5 and the first connecting member 6 in a plan view, and as shown in Figure 3, it is positioned further from the floor surface F than the first connecting member 6 (i.e., higher than the first connecting member 6).

[0035] It is desirable that the back frame 4, base frame 5, first connecting member 6, and second connecting member 7 be made of lightweight materials with excellent heat dissipation properties, such as pure aluminum (Al) or alloys containing aluminum.

[0036] In this embodiment, as shown in Figure 4, one back frame 4 and a pair of base frames 5 connected to the back frame 4 have an angle adjustment unit 20 for adjusting the angle between the pair of base frames 5. Details of this angle adjustment unit 20 will be described below.

[0037] Figure 5 is a top view showing an example of the configuration of the angle adjustment unit 20 according to the present disclosure, and is a diagram showing the first angle adjustment unit 30 provided on the back frame 4 of the angle adjustment unit 20.

[0038] The first angle adjustment section 30 has a pair of screw hole groups 31. These pair of screw hole groups 31 correspond to the through-hole groups 41 (see Figure 6) of the second angle adjustment section 40 (see Figure 6) provided in each of the pair of base frames 5 (see Figure 4). Multiple screw holes 32 are formed in the screw hole group 31.

[0039] Furthermore, the screw hole group 31 has different types of screw holes 32 formed for each angle between the pair of base frames 5 adjusted by the angle adjustment unit 20 (also referred to in this disclosure as the "mounting angle"). For example, the angle adjustment unit 20 of this disclosure has four types of mounting angles pre-set: 0°, 3°, 5°, and 7°.

[0040] In this case, the screw hole group 31 includes a screw hole 32a corresponding to a mounting angle of 0°, a screw hole 32b corresponding to a mounting angle of 3°, a screw hole 32c corresponding to a mounting angle of 5°, and a screw hole 32d corresponding to a mounting angle of 7°. In addition, multiple (two in the diagram) screw holes 32a to 32d are formed in the screw hole group 31.

[0041] Figure 6 is a top view showing an example of the configuration of the angle adjustment unit 20 according to the present disclosure, and is a diagram showing the second angle adjustment unit 40 provided on the base frame 5 of the angle adjustment unit 20.

[0042] The second angle adjustment section 40 has a group of through holes 41. Multiple through holes 42 are formed in this group of through holes 41. In addition, different types of through holes 42 are formed in the group of through holes 41 for each mounting angle adjusted by the angle adjustment section 20.

[0043] For example, the through-hole group 41 of this disclosure includes a through-hole 42a corresponding to a mounting angle of 0°, a through-hole 42b corresponding to a mounting angle of 3°, a through-hole 42c corresponding to a mounting angle of 5°, and a through-hole 42d corresponding to a mounting angle of 7°. In addition, multiple through-holes 42a to 42d are formed in each of the through-hole group 41 (two in the figure).

[0044] Figure 7 is a top view showing an example of the configuration of the angle adjustment unit 20 when the mounting angle is 0°. As shown in Figure 7, in this disclosure, for example, the base frame 5 is attached to the back frame 4 such that the second angle adjustment unit 40 of the base frame 5 (see Figure 6) overlaps the first angle adjustment unit 30 of the back frame 4 (see Figure 5).

[0045] During this installation process, the base frame 5 is attached to the back frame 4 so that the screw holes 32 and through holes 42 corresponding to the desired mounting angle align, and bolts (not shown) are screwed into the screw holes 32 through the through holes 42.

[0046] For example, in the example shown in Figure 7, since the desired mounting angle is 0°, the base frame 5 is attached to the back frame 4 such that the screw hole 32a and the through hole 42a corresponding to the mounting angle of 0° overlap, and then bolts are attached.

[0047] In this way, by mounting a pair of base frames 5 together at a mounting angle of 0°, the angle between the back frames 4 connected to each other via these base frames 5 can be set to 0°.

[0048] Therefore, according to the embodiment, as shown in Figure 8, all back frames 4 are arranged in parallel, making it possible to configure a video wall 1 in which the display screen composed of multiple display units 2 is flat. Figure 8 is a top view showing an example of the configuration of the video wall 1 and frame system 3 when the mounting angle is 0°.

[0049] Figure 9 is a top view showing an example of the configuration of the angle adjustment unit 20 when the mounting angle is 7°. In the example in Figure 9, since the desired mounting angle is 7°, the base frame 5 is attached to the back frame 4 such that the screw hole 32d and the through hole 42d corresponding to the mounting angle of 7° overlap, and bolts (not shown) are also attached.

[0050] In this way, by attaching a pair of base frames 5 to each other at an angle of 7°, the angle between the back frames 4 that are connected to each other via the base frames 5 can be set to 7°.

[0051] Therefore, according to the embodiment, as shown in Figure 10, the parallel back frames 4 are arranged at an angle of 7° each, so that the display screen composed of multiple display units 2 can be configured as a video wall 1 with a small radius of curvature. Figure 10 is a top view showing an example of the configuration of the video wall 1 and frame system 3 when the mounting angle is 7°.

[0052] Although not shown in the diagram, by attaching the base frame 5 to the back frame 4 so that the screw hole 32b (see Figure 5) and the through hole 42b (see Figure 6) corresponding to the mounting angle of 3° overlap, the angle between the pair of base frames 5 becomes 3°.

[0053] In this way, by attaching a pair of base frames 5 to each other at an angle of 3°, the angle between the back frames 4 that are connected to each other via the base frames 5 can be set to 3°.

[0054] Therefore, according to the embodiment, as shown in Figure 11, the parallel back frames 4 are arranged at an angle of 3° each, so that the display screen composed of multiple display units 2 can be configured as a video wall 1 with a large radius of curvature. Figure 11 is a top view showing an example of the configuration of the video wall 1 and frame system 3 when the mounting angle is 3°.

[0055] Although not shown in the diagram, by attaching the base frame 5 to the back frame 4 such that the screw hole 32c (see Figure 5) and the through hole 42c (see Figure 6) corresponding to the mounting angle of 5° overlap, the angle between the pair of base frames 5 becomes 5°.

[0056] In this way, by attaching a pair of base frames 5 to each other at an angle of 5°, the angle between the back frames 4 that are connected to each other via the base frames 5 can be set to 5°.

[0057] Therefore, according to the embodiment, as shown in Figure 12, the parallel back frames 4 are arranged at an angle of 5° each, so that the display screen composed of multiple display units 2 can be configured as a video wall 1 with a relatively small radius of curvature. Figure 12 is a top view showing an example of the configuration of the video wall 1 and frame system 3 when the mounting angle is 5°.

[0058] As described above, in this embodiment, the angle between adjacent back frames 4 can be easily adjusted to a desired angle by adjusting the mounting angle between a pair of base frames 5 to a desired angle using the angle adjustment unit 20.

[0059] Therefore, according to this embodiment, the angle between adjacent display units 2 in the horizontal direction can be easily adjusted to a desired angle, making it possible to easily form a large screen with a desired curvature in the video wall 1.

[0060] In addition, in this embodiment, the angle adjustment section 20 may be formed in the base frame 5 and have a plurality of through holes 42 corresponding to a plurality of mounting angles, and a plurality of screw holes 32 formed in the back frame 4 and corresponding to a plurality of mounting angles.

[0061] This allows the angle adjustment unit 20 to easily adjust the mounting angle between the pair of base frames 5 to a desired angle.

[0062] In this embodiment, it is preferable that a predetermined mounting angle is marked near the through hole 42 in the base frame 5 and near the screw hole 32 in the back frame 4. This prevents the base frame 5 from being attached to the back frame 4 at a mounting angle different from the desired angle.

[0063] Furthermore, in this embodiment, the angle adjustment unit 20 is preferably positioned at the bottom of the back frame 4 on the side that holds the display unit 2. This allows the angle adjustment unit 20 to be positioned close to the display unit 2, enabling precise adjustment of the angles between adjacent display units 2.

[0064] Furthermore, by positioning the angle adjustment unit 20 at the bottom of the back frame 4 on the side that holds the display unit 2, interference between the angle adjustment unit 20 and the display screen formed by the multiple display units 2 can be suppressed.

[0065] Figure 13 is a top view showing an example of the configuration of the mounting member 8 corresponding to an mounting angle of 0°, and Figure 14 is a top view showing an example of the configuration of the mounting member 8 corresponding to an mounting angle of 7°.

[0066] As shown in Figures 13 and 14, in this embodiment, a dedicated mounting member 8 is used depending on the desired mounting angle. Specifically, the mounting member 8 according to this embodiment has a dogbone shape in plan view and has a mounting surface 8c at the tip 8b opposite to the base end 8a that abuts against the side portion 4a of the back frame 4.

[0067] Furthermore, the mounting surface 8c has a first mounting surface 8c1 that contacts the back surface 2a of one display unit 2, and a second mounting surface 8c2 that contacts the back surface 2a of the other display unit 2. In the mounting member 8, the angle between the first mounting surface 8c1 and the second mounting surface 8c2 is set to be the same as the desired mounting angle.

[0068] For example, in the example in Figure 13, since the mounting member 8 corresponds to a mounting angle of 0°, the angle between the first mounting surface 8c1 and the second mounting surface 8c2 is set to 0°. Also, in the example in Figure 14, since the mounting member 8 corresponds to a mounting angle of 7°, the angle between the first mounting surface 8c1 and the second mounting surface 8c2 is set to 7°.

[0069] Thus, in this embodiment, by providing the mounting member 8 with a mounting surface 8c having an angle corresponding to the desired mounting angle, the contact area between the mounting member 8 and the display unit 2 can be increased even when the display screen has a desired curvature.

[0070] Therefore, according to this embodiment, the display unit 2 can be firmly attached to the back frame 4 even when the display screen has a desired curvature.

[0071] Furthermore, in this embodiment, it is preferable that the mounting member 8 can hold the corners of the display unit 2, as shown in the side view of Figure 3 and the plan view of Figure 13. This allows one mounting member 8 to simultaneously hold the corners of four display units 2, thus reducing the number of mounting members 8 required.

[0072] Therefore, according to this embodiment, the manufacturing cost of the video wall 1 can be reduced.

[0073] Furthermore, in the embodiment, as shown in Figures 3 and 4, the frame system 3 is positioned at the bottom of the back frame 4 opposite to the side that holds the display unit 2, and may include a first connecting member 6 that connects adjacent back frames 4 in a direction parallel to the floor surface F.

[0074] This allows for a stronger connection between adjacent back frames 4 compared to the case where they are connected only by the base frame 5. Therefore, according to this embodiment, it is possible to suppress the deformation of the frame system 3 due to vibrations of the floor surface F, etc.

[0075] Furthermore, in the embodiment, a dedicated first connecting member 6 may be used depending on the desired mounting angle. Specifically, the first connecting member 6 in the embodiment may gradually increase in length as the desired mounting angle increases.

[0076] This allows the first connecting member 6 to be attached without any problems to a predetermined position (for example, the bottom of the back frame 4 opposite to the side that holds the display unit 2) even if the display screen has a desired curvature.

[0077] Therefore, according to this embodiment, even when the display screen has a desired curvature, it is possible to suppress deformation of the frame system 3 due to vibrations of the floor surface F or the like.

[0078] In addition, in this embodiment, the frame system 3 may be further provided with a second connecting member 7 that is positioned further away from the floor surface F than the first connecting member 6 and connects adjacent back frames 4 in a direction parallel to the floor surface F.

[0079] This allows for a more robust connection between adjacent back frames 4 compared to the case where they are connected only by the base frame 5 and the first connecting member 6. Therefore, according to this embodiment, it is possible to further suppress the deformation of the frame system 3 caused by vibrations of the floor surface F.

[0080] Furthermore, in this embodiment, as shown in Figure 4, one second connecting member 7 may be positioned across three or more back frames 4. This allows one second connecting member 7 to simultaneously hold three or more back frames 4, thus reducing the number of second connecting members 7.

[0081] Therefore, according to this embodiment, the manufacturing cost of the video wall 1 can be reduced.

[0082] [effect] The frame system 3 according to this embodiment comprises a plurality of back frames 4 and a plurality of base frames 5. The plurality of back frames 4 are arranged side by side and are each capable of holding the back surface 2a of the display unit 2. The plurality of base frames 5 connect adjacent back frames 4 in a direction parallel to the floor surface F. In addition, the back frames 4 and the pair of base frames 5 connected to the back frames 4 have an angle adjustment unit 20 for adjusting the angle between the pair of base frames 5.

[0083] This makes it possible to easily create a large screen with the desired curvature in the video wall 1.

[0084] Furthermore, in the frame system 3 according to this embodiment, the multiple back frames 4 are arranged in a state where they are standing perpendicular to the floor surface F.

[0085] This allows the video wall 1 to be stably installed on the floor surface F.

[0086] Furthermore, in the frame system 3 according to this embodiment, the angle adjustment section 20 has a plurality of through holes 42 and a plurality of screw holes 32. The plurality of through holes 42 are formed in the base frame 5 and correspond to a plurality of angles. The plurality of screw holes 32 are formed in the back frame 4 and correspond to a plurality of angles.

[0087] This allows the angle adjustment unit 20 to easily adjust the mounting angle between the pair of base frames 5 to a desired angle.

[0088] Furthermore, in the frame system 3 according to the embodiment, the angle adjustment unit 20 is located at the bottom of the side (side portion 4a) of the back frame 4 that holds the display unit 2.

[0089] This allows for precise adjustment of the angles between adjacent display units 2, and also prevents the angle adjustment unit 20 from interfering with the display screen formed by multiple display units 2.

[0090] Furthermore, the frame system 3 according to the embodiment further includes a mounting member 8, which is positioned on the side 4a of the back frame 4 that holds the display unit 2 and is capable of directly holding the back surface 2a of the display unit 2.

[0091] This allows the display unit 2 to be firmly attached to the back frame 4, even if the display screen has a desired curvature.

[0092] Furthermore, in the frame system 3 according to the embodiment, the mounting member 8 has a mounting surface 8c having an angle corresponding to the angle between the pair of base frames 5.

[0093] This allows the display unit 2 to be firmly attached to the back frame 4, even if the display screen has a desired curvature.

[0094] Furthermore, in the frame system 3 according to this embodiment, the mounting member 8 is capable of holding the corner portion on the back surface 2a of the display unit 2.

[0095] This makes it possible to reduce the manufacturing cost of Video Wall 1.

[0096] Furthermore, in the frame system 3 according to the embodiment, the back frame 4 includes a plurality of mounting members 8 for holding the back surface 2a of the display unit 2.

[0097] This makes it possible to easily create an even larger video wall 1.

[0098] Furthermore, in the frame system 3 according to this embodiment, the mounting member 8 is capable of holding a plurality of display units 2.

[0099] This makes it possible to reduce the manufacturing cost of Video Wall 1.

[0100] Furthermore, in the frame system 3 according to this embodiment, the mounting member 8 is capable of holding four display units 2.

[0101] This makes it possible to reduce the manufacturing cost of Video Wall 1.

[0102] Furthermore, the frame system 3 according to the embodiment further includes a first connecting member 6, which is located at the bottom opposite to the side (side portion 4a) of the back frame 4 that holds the display unit 2, and connects adjacent back frames 4 in a direction parallel to the floor surface F.

[0103] This makes it possible to suppress the deformation of the frame system 3 caused by vibrations of the floor surface F.

[0104] Furthermore, in the frame system 3 according to this embodiment, the first connecting member 6 has a length corresponding to the angle between the pair of base frames 5.

[0105] This makes it possible to suppress deformation of the frame system 3 due to vibrations of the floor surface F, even when the display screen has a desired curvature.

[0106] Furthermore, the frame system 3 according to this embodiment further includes a second connecting member 7, which is positioned further away from the floor surface F than the first connecting member 6, and connects adjacent back frames 4 in a direction parallel to the floor surface F.

[0107] This further suppresses the deformation of the frame system 3 caused by vibrations of the floor surface F.

[0108] Furthermore, in the frame system 3 according to this embodiment, the second connecting member 7 is arranged between three or more back frames 4.

[0109] This makes it possible to reduce the manufacturing cost of Video Wall 1.

[0110] Furthermore, the display device (video wall 1) according to the embodiment comprises a plurality of back frames 4, a plurality of display units 2, and a plurality of base frames 5. The plurality of back frames 4 are arranged side by side. The plurality of display units 2 are held between adjacent back frames 4 and arranged in a matrix. The plurality of base frames 5 connect adjacent back frames 4 in a direction parallel to the floor surface F. In addition, the back frames 4 and the pair of base frames 5 connected to the back frames 4 have an angle adjustment unit 20 for adjusting the angle between the pair of base frames 5.

[0111] This makes it easy to realize a large-screen video wall 1 with a desired curvature.

[0112] While embodiments of this disclosure have been described above, the technical scope of this disclosure is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of this disclosure. Furthermore, components from different embodiments and modifications may be combined as appropriate.

[0113] For example, the above embodiment shows an example where the mounting angle is set to four different values: 0°, 3°, 5°, and 7°. However, this disclosure is not limited to such examples, and various types of mounting angles can be arbitrarily set.

[0114] Furthermore, the effects described herein are merely illustrative and not limiting, and other effects may also occur.
