Description

Technical Field

[0001] The present disclosure relates to a display system.

Background Art

[0002] To protect the surface of a display such as a light-emitting diode (LED) display, a cover panel such as a transparent glass panel or a resin panel may be disposed at a position facing the display. The cover panel is a panel that prevents the display from being visible when the display is not lit and allows the image to be visible when the display is lit. For example, Patent Document 1 below discloses a display device including a cover panel including a transparent panel and a display (display panel), wherein the display is disposed on the back surface of the cover panel and the cover panel is fixed to a housing.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the display device described in Patent Document 1 above, since the cover panel is fixed to the housing, when a resin plate is used as the transparent panel of the cover panel, the transparent panel may expand due to heat or water absorption, and the cover panel may be deformed.

[0005] An object of the present disclosure is to provide a display system capable of suppressing deformation of a cover panel even when the cover panel expands.

Means for Solving the Problems

[0006] One aspect of the present disclosure provides a display system comprising: a display; a cover panel disposed to cover the display; walls facing the cover panel and disposed above and below the display; and a connecting portion connecting the walls and the cover panel, wherein the connecting portion comprises an upper connecting portion provided above the display, an intermediate connecting portion provided between the upper connecting portion and the display, and a lower connecting portion provided below the display, and each of the upper connecting portion, the intermediate connecting portion and the lower connecting portion each comprises a hook fixed to the cover panel and a hook receiver fixed to the wall and having an opening, the hook each comprises an insertion portion inserted into the opening, the insertion portion of the upper connecting portion is in contact with the bottom of the opening, and the insertion portion of the intermediate connecting portion and the lower connecting portion is not in contact with the bottom of the opening. According to the display system of this disclosure, the cover panel may expand due to heating of the portion of the cover panel facing the display during use, or due to swelling of the entire cover panel due to water absorption. Even in this case, the cover panel can expand downward because the hook insertion portion does not come into contact with the bottom of the opening of the hook receiver in the intermediate and lower connecting portions. Furthermore, because the hook insertion portion is inserted into the opening of the hook receiver in the intermediate and lower connecting portions, separation of that portion from the wall is suppressed. As a result, deformation such as warping of the cover panel is suppressed. In addition, the cover panel may shrink when placed in a low-temperature environment or due to the evaporation of moisture. Even in this case, the hook insertion portion moves within the opening of the hook receiver in the intermediate and lower connecting portions, so that the portion does not get prevented from shrinking upward, and the accumulation of internal stress in the cover panel is suppressed.

[0007] The above-described display system preferably comprises a plurality of the connecting parts, and the plurality of connecting parts are arranged spaced apart from each other. In this case, since the multiple connecting parts are spaced apart from each other, even if the cover panel expands or contracts, the expansion or contraction is not hindered between the multiple connecting parts.

[0008] In the above-described display system, it is preferable that the insertion portion of the hook is slidably inserted into the opening of the hook receiver along the width direction of the cover panel. In this case, even if the cover panel expands or contracts in its width direction, the hook insertion portion slides along the width direction of the cover panel within the opening of the hook receiver, so the expansion or contraction of the cover panel in the width direction is not hindered.

[0009] In the above-described display system, the cover panel may have a light-transmitting main body and a light-transmitting decorative film laminated on the main body and having a decorative portion, and the decorative portion and the hook may be arranged to overlap in the thickness direction of the cover panel. In this case, the decorative portion of the light-transmitting decorative film and the hook are arranged to overlap in the thickness direction of the cover panel. As a result, when the display is lit, the image can be viewed through the cover panel, and when the display is not lit, the decorative portion of the light-transmitting decorative film can conceal the presence of the hook.

[0010] In the above-described display system, if the cover panel comprises a light-transmitting main body and a light-transmitting decorative film laminated on the main body and having a decorative portion, and the decorative portion and the hook are arranged to overlap in the thickness direction of the cover panel, it is preferable that the wall is black or gray and the hook is colored black or gray. In this case, the hooks become less visible through the cover panel, improving the appearance of the display system. If the cover panel does not have a light-transmitting decorative film, a light-blocking sheet may be attached to the back of the part of the cover panel other than the part where the display is shown. In that case, the wall and hook will be hidden by the light-blocking sheet, so any color is acceptable. If the color of the light-blocking sheet is adjusted to gray so that it matches the color tone of the cover panel in front of the display when the display is OFF (not lit), the difference between the part of the cover panel with the light-blocking sheet and the part without the sheet will not be visible when the display is OFF. [Effects of the Invention]

[0011] According to this disclosure, a display system is provided that can suppress deformation of the cover panel even if the cover panel expands. [Brief explanation of the drawing]

[Figure 8] Figure 8 is a cross-sectional view showing an example of a cross-sectional view of the cover panel shown in Figure 1. [Modes for carrying out the invention]

[0013] Hereinafter, an embodiment of the display system of the present disclosure will be described with reference to FIGS. 1 to 8.

[0014] The display system 100 shown in FIG. 1 includes a display 1, a cover panel 2 arranged to cover the display 1, walls 3 facing the cover panel 2 and arranged on the upper and lower sides of the display 1, and a connecting portion 6 connecting the walls 3 and the cover panel 2.

[0015] Hereinafter, the vertical direction will be described as the up-down direction D1, the thickness direction of the cover panel 2 will be described as the thickness direction D3, and the direction orthogonal to the up-down direction D1 and the thickness direction D3 will be described as the width direction D2 of the cover panel 2.

[0016] As shown in FIGS. 1 and 2, when viewing the display system 100 in the thickness direction D3, the connecting portion 6 has an upper connecting portion 6H provided on the upper side of the display 1, an intermediate connecting portion 6M provided between the upper connecting portion 6H and the display 1, and a lower connecting portion 6L provided on the lower side of the display 1.

[0017] s> As shown in FIGS. 5 and 6, each of the upper connecting portion 6H, the intermediate connecting portion 6M, and the lower connecting portion 6L has a hook 5 fixed to the cover panel 2 and a hook receiver 4 fixed to the wall 3 and having an opening 4a. The hook 5 has an insertion portion 5a inserted into the opening 4a and a connecting portion 5b connecting the insertion portion 5a and the cover panel 2. The hook receiver 4 has a side wall portion 4b forming the opening 4a between the hook receiver 4 and the wall 3 and a connecting portion 4c connecting the side wall portion 4b and the wall 3. The hook 5 is not fixed to the hook receiver 4. r>

[0018] And, as shown in FIG. 5, in the upper connecting portion 6H, the insertion portion 5a of the hook 5 does not contact the bottom portion 4d of the opening 4a of the hook receiver 4. That is, no gap is formed between the insertion portion 5a of the hook 5 and the bottom portion 4d of the opening 4a of the hook receiver 4. On the other hand, as shown in Figure 6, in the intermediate connecting portion 6M and the lower connecting portion 6L, the insertion portion 5a is not in contact with the bottom portion 4d of the opening 4a. In other words, a gap is formed between the insertion portion 5a of the hook 5 and the bottom portion 4d of the opening 4a of the hook receiver 4.

[0019] A baseboard 7 may be installed on the floor (not shown) to conceal the space between the cover panel 2 and the floor and to prevent the cover panel 2 from lifting up (see Figures 1 and 2). The baseboard 7 is not fixed to the cover panel 2.

[0020] According to the display system 100, when the display 1 is used, the part of the cover panel 2 facing the display 1 may be heated, or the entire cover panel 2 may swell due to water absorption, causing the cover panel 2 to expand. Even in this case, in the intermediate connecting section 6M and the lower connecting section 6L, the insertion part 5a of the hook 5 is not in contact with the bottom 4d of the opening 4a of the hook receiver 4, allowing the cover panel 2 to expand downwards. Also, in the intermediate connecting section 6M and the lower connecting section 6L, the insertion part 5a of the hook 5 is inserted into the opening 4a of the hook receiver 4, preventing that part from separating from the wall 3. Therefore, deformation such as warping of the cover panel 2 is suppressed. Furthermore, the cover panel 2 may shrink when placed in a low-temperature environment or due to the evaporation of moisture. Even in this case, in the intermediate connecting section 6M and the lower connecting section 6L, the insertion part 5a of the hook 5 moves relative to the opening 4a of the hook receiver 4, allowing that part to shrink upwards, thus suppressing the accumulation of internal stress in the cover panel 2. Furthermore, since the hook 5 is not fixed to the hook receiver 4, the hook 5 is not prevented from sliding laterally (in the D2 direction).

[0021] The display system 100 will be described in detail below.

[0022] <Display> Examples of display 1 include liquid crystal displays, organic electroluminescent (OLED) displays, and LED displays. The display system 100 is particularly useful when the display 1 is an LED display. This is because an LED display consists of multiple LEDs arranged in a row, and the heat generated by these multiple LEDs tends to heat the portion of the cover panel 2 facing the display 1, causing that portion to expand. Display 1, when viewed in the thickness direction D3, exhibits, for example, a rectangular shape. The shape of Display 1 may be square or rectangular. In this embodiment, the length of Display 1 along the vertical direction D1 is shorter than the width of Display 1 along the width direction D2, but the shape of Display 1 is not limited to this. In this embodiment, the surface of the display 1 on the cover panel 2 side protrudes further toward the cover panel 2 side than the wall 3 (see Figure 2). This is to secure space for the connecting portion 6 between the cover panel 2 and the wall 3.

[0023] <Wall> Wall 3 is constructed, for example, as a false wall. The material of wall 3 may be, for example, plywood or gypsum board. For example, the thickness of the plywood corresponds to the thickness of wall 3 in the thickness direction D3. The thickness of the plywood is, for example, 10 mm or more and 30 mm or less. A black or gray monochrome sheet may be attached to the surface of the plywood and gypsum board. The distance between the wall 3 and the cover panel 2 is determined so that the connecting portion 6 can be accommodated in the space between the wall 3 and the cover panel 2. The color of the surface of the cover panel 2 on the wall 3 is not particularly limited and may be, for example, black or gray.

[0024] <Cover Panel> The cover panel 2 is positioned to cover the display 1 in its thickness direction D3. In other words, the cover panel 2 is larger than the size of the display 1. Specifically, the cover panel 2 has a width greater than or equal to the width of the display 1 and a height greater than or equal to the height of the display 1. Here, the width of the display 1 refers to the length of the display 1 along the width direction D2, and the height of the display 1 refers to the length of the display 1 along the vertical direction D1.

[0025] The width of cover panel 2 is not particularly limited as long as it is greater than or equal to the width of display 1, but it may be, for example, 2m or more or 3m or more. The width W1 of cover panel 2 may be 5m or less or 4m or less. The height of the cover panel 2 is not particularly limited as long as it is greater than or equal to the height of the display 1, but it may be, for example, 1m or more, 1.5m or more, or 2m or more. The height of the cover panel 2 may be 4m or less, or 3m or less.

[0026] The thickness of the cover panel 2 is not particularly limited, but from the viewpoint of panel rigidity, it is preferably 3 mm or more, and more preferably 5 mm or more. The thickness of the cover panel 2 is preferably 10 mm or less, and more preferably 5 mm or less, from the standpoint of being lightweight and easy to handle.

[0027] The cover panel 2 is made of a light-transmitting panel, which may be a colored light-transmitting panel (also called a "smoke panel") or an uncolored light-transmitting panel, but a smoke panel is preferred. In this case, when the display 1 is lit, the image can be viewed through the cover panel 2, and when the display 1 is not lit, the cover panel 2 can conceal the presence of the display 1. The smoked panel may consist of a single component that is entirely colored, or it may be a laminate obtained by applying a smoked film to an uncolored light-transmitting component. The color of the smoked panel can be, for example, gray.

[0028] The light transmittance of the smoked panel is preferably 40% or less, more preferably 30% or less. However, from the viewpoint of making the image easier to see when the display 1 is lit, the light transmittance of the smoked panel is preferably 10% or more, more preferably 15% or more, and particularly preferably 20% or more. Here, light transmittance refers to visible light transmittance.

[0029] Materials that make up light-transmitting panels include, for example, resins such as acrylic resin, polycarbonate resin, polyvinyl chloride resin, polyethylene terephthalate (PET), and acrylonitrile butadiene styrene resin (ABS resin), as well as glass.

[0030] As shown in Figure 8, the cover panel 2 may comprise a light-transmitting main body portion 2a and a light-transmitting decorative film 2b laminated on the main body portion 2a and having a decorative portion. Here, it is preferable that the decorative portion and the hook 5 are arranged to overlap in the thickness direction D3. In this case, since the decorative portion of the light-transmitting decorative film 2b and the hook 5 are arranged to overlap in the thickness direction D3, the image can be viewed through the cover panel 2 when the display 1 is lit, and the presence of the hook 5 can be concealed by the decorative portion of the light-transmitting decorative film 2b when the display 1 is not lit. The main body part 2a may or may not be colored. The decorative part is positioned such that, for example, it does not overlap with the display 1 when viewed in the thickness direction of the cover panel 2.

[0031] The light-transmitting decorative film 2b may be laminated on the front side (opposite side from the display 1) of the main body 2a, or on the back side (display 1 side). The material constituting the main body 2a can be the same material as the material constituting the light-transmitting panel.

[0032] Furthermore, the display system 100 is particularly useful when a light-diffusing film is attached to the cover panel 2. This is because, when a light-diffusing film is attached to the cover panel 2, the image on the display 1 tends to become blurry as the distance between the display 1 and the cover panel 2 increases due to the cover panel 2 warping.

[0033] <Connection section> As described above, the connecting section 6 connects the wall 3 and the cover panel 2, and has an upper connecting section 6H, an intermediate connecting section 6M, and a lower connecting section 6L. The upper connecting section 6H, the intermediate connecting section 6M, and the lower connecting section 6L each have a hook 5 and a hook receiver 4.

[0034] (Hook) Hook 5 is fixed to the surface of the cover panel 2 on the display 1 side, as shown in Figure 4. It is preferable that the hook 5 has rigidity so that it does not bend easily. In this case, the part of the cover panel 2 to which the hook 5 is fixed will not warp, so the hook 5 itself can suppress warping of the cover panel 2. Examples of materials that make up the hook 5 include wood, plastic, and metal. Among these, metal is preferred because it is less prone to warping and has high rigidity. Examples of metals include iron. The shape of the hook 5 is not particularly limited as long as it has an insertion portion 5a that is inserted into the opening 4a of the hook receiver 4. In this embodiment, the hook 5 has an insertion portion 5a and a connecting portion 5b. The shape of the insertion portion 5a is not particularly limited, but it may be, for example, plate-shaped. The thickness of the insertion portion 5a is not particularly limited, but it is preferable that it be thick enough to have rigidity that makes it difficult to bend. If the insertion portion 5a is made of iron, it is preferable that the thickness of the insertion portion 5a is 1.6 mm or more. By making the thickness of the insertion portion 5a 1.6 mm or more, the insertion portion 5a and the connecting portion 5b become less likely to bend due to the force that causes the cover panel 2 to bend. Also, since a large load is applied downwards due to the weight of the hook 5, when the cover panel 2 expands, it is more likely to expand downwards than to bend. The thickness of the connecting portion 5b is preferably 1.6 mm or more. However, the thickness of the insertion portion 5a and the connecting portion 5b is preferably such that it reduces the risk of detachment due to weight. If the insertion portion 5a is made of iron, it is preferably 5 mm or less, and more preferably 3 mm or less. The connecting portion 5b of the hook 5 is fixed to the surface of the cover panel 2 on the wall 3 side (see Figure 5). The connecting portion 5b can be fixed to the cover panel 2 using adhesive, double-sided tape, screws, or a combination thereof. Figure 5 shows a configuration in which the hook 5 is fixed to the cover panel 2 using screws 8. It is preferable that the screws 8 be arranged vertically and horizontally (i.e., in the vertical direction D1 and the width direction D2) and fixed in four or more places. It is preferable that the hook 5 of the upper connecting portion 6H, which is subjected to load, be fixed to the cover panel 2 with screws 8 to prevent the hook 5 from falling. The insertion portion 5a and the connecting portion 5b are joined, for example, by welding, but they may also be formed by processing a single component. The insertion portion 5a is slidably inserted within the opening 4a of the hook receiver 4 along the width direction (i.e., width direction D2) of the cover panel 2. When the cover panel 2 is equipped with a light-transmitting decorative film 2b having a decorative portion, the color of the hook 5 is preferably black or gray if the color of the wall 3 is black or gray. In this case, the hook 5 will be less conspicuous when viewed in the thickness direction D3 from the surface of the cover panel 2 opposite to the wall 3. In particular, if the color of the wall 3 is black, the hook 5 can be made even less conspicuous if it is black. Similarly, if the color of the wall 3 is gray, the hook 5 can also be made less conspicuous if it is gray. However, since the reflected light from the hook 5 appears darker than the reflected light from the wall 3 with respect to light incident from the surface of the cover panel 2 opposite to the wall 3, it is preferable to adjust the gray density of the hook 5 to be lower than the gray density of the wall 3. In this case, the difference in intensity between the reflected light from the hook 5 and the reflected light from the wall 3 can be reduced, making the presence of the hook 5 even less conspicuous. Furthermore, a gray concealing layer may be provided between the portion of the cover panel 2 that does not face the display 1 and the hook 5. In this case, the difference in intensity between the reflected light from the surface of the display 1 and the reflected light from the gray concealing layer can be reduced for light incident from the surface of the cover panel 2 opposite to the wall 3. The concealing layer may be formed by applying a sheet or by printing.

[0035] (Hook receiver) The hook receiver 4 is fixed to the surface of the wall 3 on the cover panel 2 side (see Figure 3). The hook receiver 4 preferably has rigidity so that it does not bend easily. In this case, the load-bearing capacity of the cover panel 2 can be improved. The materials that make up the hook receiver 4 include wood, plastic, and metal. Among these, metal is preferred because it is less prone to warping and has high rigidity. An example of a metal is iron. The shape of the hook receiver 4 is not particularly limited as long as it has an opening 4a into which the insertion portion 5a of the hook 5 is inserted. In this embodiment, the hook receiver 4 has a side wall portion 4b and a connecting portion 4c. The shape of the connecting portion 4c and the side wall portion 4b is not particularly limited, but they may be plate-shaped, for example. The thickness of the connecting portion 4c is preferably greater than the thickness of the insertion portion 5a of the hook 5, so as not to hinder the movement of the hook 5 due to the expansion and contraction of the cover panel 2. The difference in thickness between the side wall portion 4b and the insertion portion 5a is preferably 1 mm or less, and more preferably 0.5 mm or less. It is preferable that the thickness of the side wall portion 4b be less than the thickness of the connection portion 5b of the hook 5 so as not to hinder the movement of the cover panel 2 due to expansion and contraction. It is preferable that the thickness of the side wall portion 4b be such that it is difficult to bend. For example, if the side wall portion 4b is made of iron, it is preferable that the thickness of the side wall portion 4b be 1.6 mm or more. The connecting portion 4c of the hook receiver 4 is fixed to the surface of the wall 3. The connecting portion 4c can be fixed to the surface of the wall 3 using adhesive, double-sided tape, screws, or a combination of these. It is preferable that the screws are arranged vertically and horizontally (i.e., in the vertical direction D1 and the width direction D2) and secured in four or more places. Figure 7 is a front view showing an example of a hook receiver 4, where reference numeral 4e indicates four screw holes (through holes) formed in the connecting portion 4c. The connecting portion 4c and the side wall portion 4b are joined, for example, by welding, but they may also be formed by processing a single member. When the cover panel 2 is equipped with a light-transmitting decorative film 2b having a decorative portion, the color of the hook receiver 4 may be black or gray if the wall 3 is black or gray. In this case, the hook receiver 4 will be less conspicuous when viewed in the thickness direction D3 from the surface of the cover panel 2 opposite to the wall 3. In particular, if the wall 3 is black, the hook receiver 4 will be less conspicuous if it is black. Similarly, if the wall 3 is gray, the hook receiver 4 will also be less conspicuous if it is gray.

[0036] (Upper connecting part) In the upper connecting section 6H, a load is applied to the hook receiver 4 from the hook 5. The upper connecting portion 6H is preferably located on the upper part of the cover panel 2. To avoid hindering the lateral expansion (D2 direction) of the cover panel 2, it is preferable to install multiple upper connecting parts 6H along the lateral direction (D2 direction) of the cover panel 2, spaced apart as shown in Figure 1. The more connecting parts there are, the smaller the load on the cover panel 2 per upper connecting part 6H becomes. Smaller loads result in less friction, making it less likely for the lateral movement of the hooks 5 to be hindered. The upper connecting parts 6H are installed such that, for example, hooks 5 with a width of 100 mm are arranged at a pitch of 200 mm. At the upper connecting section 6H, the load of the cover panel 2 is applied to the hook 5 and the hook receiver 4. Therefore, it is preferable to use screws in addition to adhesive or double-sided tape to fix the hook 5 to the cover panel 2 and the hook receiver 4 to the wall 3. In the upper connecting portion 6H, the upper end surface (bottom portion 4d) of the connecting portion 4c of the hook receiver 4 is in contact with the insertion portion 5a of the hook 5, but since it is not glued, the insertion portion 5a can be slid (see Figure 5). The upper end surface is, for example, a flat surface. A rotating body such as a roller may be embedded in the upper end surface of the connecting portion 4c of the hook receiver 4. In this case, the insertion portion 5a will slide more easily on the upper end surface of the connecting portion 4c.

[0037] (Intermediate connecting section and lower connecting section) In the intermediate connecting section 6M and the lower connecting section 6L, no load is applied to the hook receiver 4 from the hook 5. Therefore, the insertion portion 5a of the hook 5 is not in contact with the bottom portion 4d of the hook receiver 4. The intermediate connecting section 6M is preferably positioned directly above the display 1 in order to suppress thermal deformation of the cover panel 2. Specifically, the intermediate connecting section 6M is preferably installed so that its hook receiver 4 is positioned at the lower end of the wall 3 (such as a false wall) above the display 1. From the viewpoint of suppressing warping of the cover panel 2 and not hindering the lateral expansion (D2 direction) of the cover panel 2, it is preferable that there be multiple intermediate connecting sections 6M spaced apart, as shown in Figure 1. The portion of the cover panel 2 between adjacent intermediate connecting sections 6M can be made to expand or contract. The intermediate connecting sections 6M are installed such that, for example, hooks 5 with a width of 100 mm are arranged at a pitch of 200 mm. The lower connecting portion 6L is preferably positioned directly below the display 1 in order to suppress deformation of the cover panel 2 due to heat. Specifically, the lower connecting portion 6L is preferably installed so that the hook receiver 4 is positioned at the upper edge of the wall 3 (such as a false wall) below the display 1. From the viewpoint of suppressing warping of the cover panel 2 and not hindering the lateral expansion (D2 direction) of the cover panel 2, it is preferable that there be multiple lower connecting parts 6L spaced apart along the lateral direction (D2 direction) of the cover panel 2, as shown in Figure 1. The portion of the cover panel 2 between adjacent lower connecting parts 6L can be made to expand or contract. The lower connecting parts 6L are installed such that, for example, hooks 5 with a width of 100 mm are arranged at a pitch of 200 mm. The weight of the lower connecting section (6L) makes the lower part of the cover panel 2 heavier than the display 1, which makes it more prone to expanding downwards, thus reducing the likelihood of the cover panel 2 warping. In the intermediate connecting section 6M and the lower connecting section 6L, the insertion portion 5a of the hook 5 and the bottom portion 4d of the opening 4a of the hook receiver 4 are not in contact. Therefore, a rotating body such as a roller does not need to be embedded in the bottom portion 4d of the opening 4a.

[0038] <baseboard> Baseboard 7 is not fixed to cover panel 2. The baseboard 7 comprises a strip-shaped fixing portion 7a provided along the cover panel 2, and a side wall portion 7b extending in the vertical direction D1 from one side edge of the fixing portion 7a furthest from the wall 3 (see Figure 2). The side wall portion 7b abuts against the lower end of the cover panel 2.

[0039] Examples of materials that make up the baseboard 7 include metals such as aluminum and iron. [Examples]

[0040] The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples.

[0041] (Example 1) An LED display measuring 600mm wide and 1000mm high was installed on the main wall. A false wall measuring 604mm wide and 400mm high was installed above the LED display, and another false wall measuring 604mm wide and 1000mm high was installed below the LED display, facing the main wall. False walls measuring 148mm wide and 2400mm high were installed on the left and right sides of the LED display. Black sheets were applied to the surface of the false walls. The false walls were installed 2mm behind the front surface of the LED display. Furthermore, two iron plates, one measuring 50mm wide, 50mm high, and 1.6mm thick, and the other 50mm wide, 100mm high, and 1.6mm thick, were welded together with one end face aligned to form the connecting and inserting parts, respectively. They were then painted black and baked to create a hook shape. This was used as the hook. The connecting part of the hook, which is fixed with screws, had two screw holes vertically and two horizontally. Furthermore, two iron plates, one measuring 50mm wide, 50mm high, and 1.6mm thick, and the other 50mm wide, 100mm high, and 1.6mm thick, were welded together with one end face aligned to form the connecting part and side wall, then painted black to create the shape of a hook receiver. This was used as the hook receiver for the upper connecting part. The connecting part of the hook receiver, which is fixed with screws, had two screw holes vertically and two horizontally. Next, as the upper connecting section, five hook receivers were fixed at 100mm intervals, 50mm below the upper edge of the false wall above the LED display. The hook receivers were fixed to the false wall with four screws. Additionally, two iron plates, one measuring 50mm wide, 50mm high, and 1.8mm thick, and the other 50mm wide, 100mm high, and 1.4mm thick, were welded together with one end face aligned to form the connecting and inserting parts, respectively. They were then painted black and baked to create a hook shape. This was used as the hook for the intermediate connecting section. The connecting part of the hook, which is fixed with screws, had two screw holes vertically and two horizontally. Furthermore, two iron plates, one measuring 50mm wide, 50mm high, and 1.8mm thick, and the other 50mm wide, 100mm high, and 1.4mm thick, were welded together with one end face aligned to form the connecting section and side wall section. They were then painted black and baked to create the shape of a hook receiver. This was used as the hook receiver for the intermediate connecting section. The connecting section of the hook receiver, which is fixed with screws, had two screw holes vertically and two horizontally. Then, as with the upper connecting section, five hook receivers were fixed at 100mm intervals to the lower edge of the wall above the LED display, serving as intermediate connecting sections. The hook receivers were secured to the false wall with four screws. Furthermore, two iron plates, one measuring 50mm wide, 50mm high, and 1.8mm thick, and the other 50mm wide, 100mm high, and 1.4mm thick, were welded together with one end face aligned to form the connecting and inserting parts, respectively. They were then painted black and baked to create a hook shape. This was used as the hook for the lower connecting part. The connecting part of the hook, which is fixed with screws, had two screw holes vertically and two horizontally. Furthermore, two iron plates, one measuring 50mm wide, 50mm high, and 1.8mm thick, and the other 50mm wide, 100mm high, and 1.4mm thick, were welded together with one end face aligned to form the connection and side wall sections. They were then painted black and baked to create the shape of a hook receiver. This was used as the hook receiver for the lower connecting section. The connection section of the hook receiver, which is fixed with screws, had two screw holes vertically and two horizontally. Then, similar to the intermediate connection section, five hook receivers were fixed at 100mm intervals, 50mm below the upper edge of the wall below the LED display, to serve as the lower connection section. The hook receivers were fixed to the false wall with four screws. Furthermore, hooks were attached to the back of a smoked polycarbonate sheet (cover panel) measuring 900mm wide, 2380mm high, and 5mm thick, in a position where they could be inserted into the opening of the hook receiver of the upper connecting section attached to the false wall, using a combination of double-sided tape and screws. Then, the hooks of the intermediate and lower connecting sections were attached to the back of the smoked polycarbonate sheet using double-sided tape, in the same way as the hooks of the upper connecting section, so that there was a 0.4mm gap between the hook receiver and the hook of the intermediate and lower connecting sections. Next, the cover panel with the attached hooks was positioned opposite the LED display, lifted 50mm, pressed against the false wall, and then lowered, inserting all the hooks into the openings of the hook receivers fixed to the false wall. In this way, 15 connecting points were formed at 100mm intervals in the width direction of the cover panel. At this time, a gap of approximately 1.2mm was formed between the LED display and the cover panel. Finally, L-shaped angles were fixed to the floor beneath the cover panel as a baseboard, and the lower edge of the cover panel was held down with the angles to prevent the cover panel from lifting up. The display system was fabricated in the manner described above.

[0042] (Comparative Example 1) The display system was constructed in the same manner as in Example 1, except that the hook receivers were not fixed to the false wall, the hooks were not fixed to the cover panel, and the top of the cover panel was screwed to the false wall at five evenly spaced points.

[0043] In Comparative Example 1, the heat from the LEDs in the LED display caused the cover panel to expand and bulge, creating a gap of about 20 mm between the LED display and the cover panel. In contrast, in Example 1, even when the cover panel expanded, it stretched downwards and to the sides, and the cover panel did not bulge. Therefore, it has been confirmed that the display system of this disclosure can suppress deformation of the cover panel even if the cover panel expands. [Explanation of Symbols]
