Description

Technical Field

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

Background Art

[0002] In order to protect the surface of a display such as a light-emitting diode (LED) display, a cover panel having a light-transmissive decorative sheet or the like may be disposed opposite. The cover panel is a panel that does not allow the display to be visually recognized when the display is turned off, and allows the image to be visually recognized when the display is turned on. For example, Patent Document 1 below discloses a display device including a cover panel (optical film) including a colored semi-transmissive member and a display (display panel), the display being disposed on the back surface of the cover panel, and the cover panel being installed on the display via 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, when the surface of the display is covered with a cover panel larger than the display, when a part of the display is replaced in case of failure, it is necessary to remove the cover panel and open the front of the display to be replaced. If the cover panel is heavy and large, the series of operations of removal and attachment involves various risks, becomes very difficult, and requires a great deal of labor and cost to realize such operations.

[0005] An object of the present disclosure is to provide a display system that can easily perform maintenance of a display covered with a cover panel. [Means for solving the problem]

[0006] One aspect of this disclosure provides a display system comprising a display, a cover panel positioned opposite the display and capable of covering the display, and rails for slidably suspending the cover panel. According to the display system of this disclosure, the display can be easily exposed by sliding the cover panel along the rail, thereby facilitating maintenance of the display.

[0007] In the above-described display system, it is preferable that the cover panel is suspended from the rail via a plurality of panel suspension parts. In this case, even if the cover panel is heated and expands due to the display, it becomes possible to increase the distance between adjacent panel suspension points, absorbing the lateral (widthwise) expansion of the cover panel and suppressing warping of the cover panel.

[0008] The display system further comprises a pair of dummy panels positioned on both sides of the cover panel along the rail, wherein a portion of each of the pair of dummy panels is preferably movable away from the rail. In this case, under normal circumstances, the dummy panels are positioned along the rails on both sides of the cover panel. This conceals both sides of the cover panel with a pair of dummy panels, improving the appearance. Additionally, by moving a portion of the dummy panel away from the rail, the cover panel can be slid along the rail.

[0009] In the above-described display system, it is preferable that each of the pair of dummy panels is rotatable by a hinge around an axis passing through the side edge furthest from the cover panel. In this case, the dummy panel can be easily moved away from the rail without removing it by rotating it around an axis that passes through the side edge furthest from the cover panel, using a hinge.

[0010] In the above-described display system, it is preferable that the sum of the widths of the pair of dummy panels is equal to or greater than the width of the cover panel. In this case, maintenance can be performed across the entire surface of the display. Furthermore, compared to the case where a dummy panel can be placed on only one side of the cover panel, the width of each dummy panel in this pair can be made narrower than the width of such a dummy panel. As a result, the pair of dummy panels can be easily manufactured, opened and closed, and require less space in front (opposite the rail relative to the dummy panel) for opening and closing.

[0011] In the above-described display system, the cover panel may be a colored transparent panel. In this case, the cover panel being a colored transparent panel allows the image to be viewed through the cover panel when the display is lit, and conceals the presence of the display when it is not lit.

[0012] 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. In this case, when the display is lit, the image can be viewed through the cover panel, and when the display is not lit, the presence of the display can be concealed by the decorative part of the light-transmitting decorative film. [Effects of the Invention]

BEST MODE FOR CARRYING OUT THE INVENTION

[0015] <<First Embodiment>> Hereinafter, a first embodiment of the display system of the present disclosure will be described with reference to FIGS. 1 to 6.

[0016] First, the structure S on which the display system 100 is installed will be described. It should be noted that there seems to be a problem with the "? " in the translation of ID=23. It is recommended to check and correct the original text if possible.As shown in Figure 2, the structure S has a floor 8 and a main wall 9 extending in a direction perpendicular to the surface of the floor 8. Here, the direction perpendicular to the surface of the floor 8 (i.e., the height direction of the main wall 9) is described as the vertical direction D1, the width direction of the main wall 9 is the left-right direction D2, and the thickness direction of the main wall 9 is the thickness direction D3. For example, the left-right direction D2 and the thickness direction D3 are directions parallel to the surface of the floor 8 (e.g., the horizontal direction), and the vertical direction D1 is, for example, the vertical direction. The vertical direction D1, the left-right direction D2, and the thickness direction D3 are perpendicular to each other.

[0017] The structure S further comprises a ceiling 1 facing the floor 8, side walls 9a and 9b that connect the floor 8 and the ceiling 1 and are positioned opposite each other and located on both sides of the main wall 9, and an auxiliary wall 10 that faces the main wall 9, is located between the side walls 9a and 9b, and has an opening 10a (see Figures 1 to 3).

[0018] The auxiliary wall 10 is, for example, a false wall. A gap is formed between the main wall 9 and the auxiliary wall 10 (see Figure 2). That is, the auxiliary wall 10 is positioned away from the main wall 9 in the thickness direction D3. This allows the heat emitted from the display 15 to be dissipated to the outside without accumulating in the main wall 9.

[0019] The material of the auxiliary wall 10 may be, for example, plywood or gypsum board. For example, the thickness of the plywood corresponds to the thickness of the auxiliary wall 10 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.

[0020] The display system 100 includes a display 15 fixed to the main wall 9, a cover panel 2 positioned opposite the display 15 and capable of covering the display 15, and rails 4 that slidably suspend the cover panel 2 (see Figure 2 or Figure 3).

[0021] The display 15 is positioned such that the surface on which the image is displayed is perpendicular to the thickness direction D3. The rail 4 is fixed to the auxiliary wall 10 along the left-right direction D2. The rail 4 includes, for example, a rail support portion 4a fixed to the surface of the auxiliary wall 10 and extending linearly along the left-right direction D2, and a projection portion 4b that protrudes from the rail support portion 4a toward the front side (cover panel 2 side) (see Figure 2).

[0022] The cover panel 2 is suspended slidably along the rail 4 via the panel suspension portion 5. In this embodiment, the panel suspension portion 5 is composed of a projection 5a fixed to the surface on the main wall 9 side (see Figure 3). A lower frame member 7 that guides the cover panel 2 may be installed on the floor 8 along the left-right direction D2 (see Figure 3). The ceiling 1 may be provided with an upper pressing member 16 that holds down the upper part of the cover panel 2 along the left-right direction D2 (see Figure 3).

[0023] The display system 100 also includes a first dummy panel 11a positioned along the rail 4 on the left side of the cover panel 2 (between the side wall 9a and the cover panel 2), and a second dummy panel 11b positioned along the rail 4 on the right side of the cover panel 2 (between the side wall 9b and the cover panel 2).

[0024] The first dummy panel 11a is rotatable around an axis 13a passing through the side edge furthest from the cover panel 2, by two hinges 13 fixed to the upper and lower ends of the side edge (see Figures 2, 4, and 5). The two hinges 13 are fixed to the auxiliary wall 10. Therefore, by rotating the first dummy panel 11a around the axis 13a passing through the side edge using the two hinges 13, a part of the first dummy panel 11a (the part other than the side edge) can be easily moved away from the rail 4 without removing the first dummy panel 11a. The first dummy panel 11a may have an upper retaining dummy member 17a installed along its upper edge, and a lower frame dummy member 18a installed along its lower end (see Figure 1).

[0025] The second dummy panel 11b is rotatable around an axis 13a passing through the side edge furthest from the cover panel 2, by two hinges 13 fixed to the upper and lower ends of the side edge (see Figures 2 and 4). The two hinges 13 are fixed to the auxiliary wall 10. Therefore, by rotating the second dummy panel 11b around the axis 13a passing through the side edge using the two hinges 13, a part of the second dummy panel 11b (the part other than the side edge) can be easily moved away from the rail 4 without removing the second dummy panel 11b. The second dummy panel 11b may have an upper retaining dummy member 17b installed along its upper edge, and a lower frame dummy member 18b installed along its lower end (see Figure 1).

[0026] According to the display system 100, under normal circumstances, the cover panel 2 is positioned opposite the display 15 and covers the display 15. However, when a malfunction occurs in the display 15, for example, the first dummy panel 11a is rotated by two hinges 13 around an axis 13a passing through the side edge furthest from the cover panel 2, moving a portion of the first dummy panel 11a (the portion other than the side edge) away from the rail 4, and the cover panel 2 is slid along the rail 4 to the left of the display 15 (see Figure 5). Also, the second dummy panel 11b is rotated by two hinges 13 around an axis 13a passing through the side edge furthest from the cover panel 2, moving a portion of the second dummy panel 11b (the portion other than the side edge) away from the rail 4, and the cover panel 2 is slid along the rail 4 to the right of the display 15. In this way, the display 15 can be easily exposed, making it easier to perform maintenance on the display 15.

[0027] Furthermore, according to the display system 100, under normal circumstances, the first dummy panel 11a is positioned to the left of the cover panel 2 along the rail 4, and the second dummy panel 11b is positioned to the right of the cover panel 2 along the rail 4. As a result, the auxiliary walls 10 on both sides of the cover panel 2 are hidden by the first dummy panel 11a and the second dummy panel 11b, improving the appearance.

[0028] The display system 100 will be described in detail below.

[0029] <Display> Examples of the display 15 include liquid crystal displays, organic electroluminescent (OLED) displays, and LED displays. The display system 100 is particularly useful when the display 15 is an LED display. This is because an LED display consists of multiple LEDs arranged in a grid, and if some of the LEDs fail to light up, it is necessary to pull out the faulty LEDs from the cover panel 2 side of the display 15 and replace them with new LEDs. Viewed from the thickness direction D3, the display 15 has, for example, a rectangular shape. The shape of the display 15 may be square or rectangular. In this embodiment, the height H2 of the display 15 along the vertical direction D1 is shorter than the width W2 of the display 15 along the horizontal direction D2, but the shape of the display 15 is not limited to this. The display 15 may be inserted into the opening 10a of the auxiliary wall 10, as shown in Figure 3. In this case, since the display 15 is supported not only by the main wall 9 but also by the auxiliary wall 10, the gravity of the display 15 is distributed between the main wall 9 and the auxiliary wall 10, and the concentration of load between the display 15 and the main wall 9 can be suppressed. The surface of the display 15 on the cover panel 2 side and the surface of the auxiliary wall 10 on the cover panel 2 side may or may not be on the same plane, but from the viewpoint of improving appearance, it is preferable that they be on the same plane. In Figure 1, the display 15 is fixed to the main wall 9 and inserted into the opening 10a of the auxiliary wall 10. However, the auxiliary wall 10 may be removed and the display 15 may be embedded in the main wall 9.

[0030] <Cover Panel> The cover panel 2 is positioned opposite the display 15 and the auxiliary wall 10. In other words, the cover panel 2 is positioned further from the main wall 9 in the thickness direction D3 than the display 15 and the auxiliary wall 10. The cover panel 2 is capable of covering the display 15, and specifically has a width W1 that is equal to or greater than the width W2 of the display 15, and a height H1 that is equal to or greater than the height H2 of the display 15. Here, the width W2 of the display 15 refers to the length of the display 15 along the left-right direction D2, and the height H2 of the display 15 refers to the length of the display 15 along the up-down direction D1.

[0031] The width W1 of the cover panel 2 is not particularly limited as long as it is greater than or equal to the width W2 of the display 15, but it may be, for example, 1m or more or 2m or more. The width W1 of the cover panel 2 may be 4m or less or 3m or less. The height H1 of the cover panel 2 is not particularly limited as long as it is greater than or equal to the height H2 of the display 15, but may be, for example, 1m or more, 1.5m or more, or 2m or more. The height H1 of the cover panel 2 may be 4m or less, or 3m or less.

[0032] The thickness of cover panel 2 is not particularly limited, but may be, for example, 5 mm or more, 7 mm or more, or 9 mm or more. The thickness of cover panel 2 may be 20 mm or less, 17 mm or less, or 15 mm or less.

[0033] The cover panel 2 is made of a transparent panel, which may be a colored transparent panel (also called a "smoke panel") or an uncolored transparent panel, but a colored transparent panel is preferred. In this case, when the display 15 is lit, the image can be viewed through the cover panel 2, and when the display 15 is not lit, the cover panel 2 can conceal the presence of the display 15.

[0034] The light transmittance of the colored transparent 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 15 is lit, the light transmittance of the colored transparent panel is preferably 3% or more, more preferably 5% or more, and particularly preferably 10% or more. Here, light transmittance refers to the transmittance of visible light.

[0035] Materials that make up transparent panels include resins such as acrylic resin, polycarbonate resin, polyvinyl chloride resin, polyethylene terephthalate (PET), and acrylonitrile butadiene styrene resin (ABS resin), as well as glass.

[0036] As shown in Figure 6, the cover panel 2 may comprise a light-transmitting main body 2a and a light-transmitting decorative film 2b laminated on the main body 2a and having a decorative portion. In this case, when the display 15 is lit, the image can be viewed through the cover panel 2, and when the display 15 is not lit, the decorative portion of the light-transmitting decorative film 2b can conceal the presence of the display 15.

[0037] The light-transmitting decorative film 2b may be laminated on the front side (opposite side from the display 15) of the main body 2a, or on the back side (towards the display 15). The materials that make up the main body 2a can be the same materials that make up the transparent panel.

[0038] <rail> The rail 4 is fixed to the auxiliary wall 10, but if the structure S does not have an auxiliary wall 10, it may be fixed to the main wall 9 or to the ceiling 1. The length of the rail 4 is not particularly limited, but is preferably at least twice the width W1 of the cover panel 2, and more preferably twice the width W1 of the cover panel 2. However, the length of the rail 4 may be no more than three times the width W1 of the cover panel 2, or no more than 2.5 times the width W1 of the cover panel 2.

[0039] For example, metals such as aluminum or iron can be used as the material for the rail 4. A sliding material 6 may be provided on the ceiling 1 side of the protruding portion 4b to allow the cover panel 2 to slide smoothly.

[0040] As the lubricant 6, a material with a low coefficient of dynamic friction between the lubricant 6 and the projection 5a is preferred. Examples of materials with a low coefficient of dynamic friction include resins such as fluororesins and polyolefin resins. Examples of polyolefin resins include polyethylene (PE) and polypropylene.

[0041] <Panel suspension section> The panel suspension section 5 suspends the cover panel 2 and, in this embodiment, is composed of a projection 5a. The projection 5a is fixed to the back side (display 15 side) of the cover panel 2. The shape of the projection 5a is, for example, a flat plate. The thickness of the projection 5a may be less than or greater than the protrusion amount of the rail 4's projection 4b, but it is preferable that it be less than or equal to the protrusion amount of the rail 4's projection 4b. In this case, the posture of the cover panel 2 can be stabilized. The projection 5a abuts against the surface of the projection 4b of the rail 4, thereby suspending the cover panel 2 from the rail 4.

[0042] The protrusion 5a may consist of only one or multiple protrusions, but it is preferable that it consists of multiple protrusions. In this case, even if the cover panel 2 is heated and expands by the display 15, it is possible to increase the distance between adjacent protrusions 5a, thereby absorbing the lateral (widthwise) expansion of the cover panel 2 and suppressing warping of the cover panel 2.

[0043] When the projections 5a consist of multiple parts, the multiple projections 5a may be arranged with or without spacing along the upper edge of the cover panel 2, but it is preferable to arrange them with spacing along the upper edge of the cover panel 2. In this case, even if the cover panel 2 shrinks, it becomes possible to reduce the distance between adjacent projections 5a, thereby absorbing the shrinkage of the cover panel 2 and suppressing warping of the cover panel 2.

[0044] In the case of multiple protrusions 5a, it is preferable that adjacent protrusions 5a are not bonded to each other. In this case, even if the cover panel 2 is heated and expands by the display 15, the distance between adjacent protrusions 5a can be easily increased, the lateral (widthwise) expansion of the cover panel 2 can be easily absorbed, and the warping of the cover panel 2 can be easily suppressed. It is preferable that the projection 5a is firmly fixed to the cover panel 2 with adhesive or screws so as not to detach from it.

[0045] The protrusion 5a is made of resin such as acrylic resin, polycarbonate resin, polyvinyl chloride resin, polyethylene terephthalate (PET), acrylonitrile butadiene styrene resin (ABS resin); wood; or metal such as aluminum.

[0046] <Lower frame member> The lower frame member 7 is a component that prevents the cover panel 2 from moving back and forth (in the thickness direction D3). The lower frame member 7 is not fixed to the cover panel 2. The lower frame member 7 does not obstruct the sliding of the cover panel 2. The lower frame member 7 comprises a strip-shaped lower frame support portion 7a provided along the cover panel 2, and a pair of side wall portions 7b extending toward the ceiling 1 from both edges of the lower frame support portion 7a (see Figure 3).

[0047] The thickness of the side wall portion 7b is not particularly limited, but it is preferable that it is a thickness that has sufficient strength to prevent deformation of the cover panel 2 and to prevent it from falling over when pressed. The thickness of the side wall portion 7b may be, for example, 0.1 cm or more or 0.15 cm or more. The thickness of the side wall portion 7b may be 0.5 cm or less or 0.2 cm or less.

[0048] It is preferable that the lower frame member 7 is installed such that a gap is formed between the lower frame support portion 7a and the cover panel 2. In this case, the lower frame member 7 does not hinder the expansion of the cover panel 2 even if it expands due to the heat of the display 15. In addition, since there is no friction between the lower frame support portion 7a and the cover panel 2, the cover panel 2 slides smoothly.

[0049] Examples of materials that make up the lower frame member 7 include metals such as aluminum and iron. The lower frame member 7 may also be made of resin or wood, provided that it has sufficient strength.

[0050] The lower frame member 7 may also have a fixing portion (not shown) that secures the cover panel 2 to prevent it from sliding during normal operation. Here, it is preferable that the fixing position of the cover panel 2 by the fixing portion is at a single point in the center of the width direction (left-right direction D2) of the cover panel 2. In this case, even if the cover panel 2 expands to the left or right due to the heat of the display 15, the lower frame member 7 will not hinder that expansion.

[0051] <Upper retaining member> The upper retaining member 16 guides the cover panel 2 along the rail 4 (along the left-right direction D2) and prevents the cover panel 2 from detaching from the rail 4. The thickness of the upper pressing member 16 is not particularly limited, but may be, for example, 0.1 cm or more, 0.15 cm or more, or 0.2 cm or more. The thickness of the upper pressing member 16 may be 1.5 cm or less, 1 cm or less, or 0.5 cm or less.

[0052] It is preferable that the upper retaining member 16 is installed such that a gap is formed between it and the cover panel 2. In this case, the upper retaining member 16 does not hinder the expansion of the cover panel 2 even if it expands due to the heat of the display 15. In addition, since there is no friction between the upper retaining member 16 and the cover panel 2, the cover panel 2 slides smoothly. Examples of materials that can make up the upper pressing member 16 include metals such as aluminum and iron. The upper pressing member 16 may also be made of resin or wood, provided that it has sufficient strength.

[0053] <First dummy panel and second dummy panel> In this embodiment, the first dummy panel 11a and the second dummy panel 11b are rotatably mounted around an axis 13a by two hinges 13, and can be easily removed from the rail 4 at any time without removing the first dummy panel 11a and the second dummy panel 11b. In addition, the first dummy panel 11a and the second dummy panel 11b can conceal the auxiliary wall 10 on the back side of the first dummy panel 11a and the second dummy panel 11b, thereby making the presence of the cover panel 2 less noticeable. The material and thickness of the first dummy panel 11a and the second dummy panel 11b may be the same as or different from those of the cover panel 2.

[0054] It is preferable that the surfaces of the first dummy panel 11a and the second dummy panel 11b opposite to the main wall 9 are on the same plane as the surface of the cover panel 2 opposite to the display 15. In this case, there is no step between the surfaces of the first dummy panel 11a and the second dummy panel 11b opposite to the main wall 9 and the surface of the cover panel 2 opposite to the display 15, thus improving the appearance.

[0055] It is preferable that the first dummy panel 11a and the second dummy panel 11b are arranged so that a gap is formed between them and the cover panel 2. In this case, even if the cover panel 2 expands due to heat, the first dummy panel 11a and the second dummy panel 11b will be less likely to come into contact with the cover panel 2, and the rotation of the first dummy panel 11a and the second dummy panel 11b due to contact will be less likely to be hindered.

[0056] When the display 15 is not lit, the cover panel 2 and the first dummy panel 11a and the second dummy panel 11b may or may not appear identical, but from the viewpoint of improving appearance, it is preferable that they appear identical. Alternatively, the first dummy panel 11a and the second dummy panel 11b may have a pattern that is aesthetically different from the pattern of the cover panel 2.

[0057] The sum of the widths W3 of the first dummy panel 11a and W4 of the second dummy panel 11b may be greater than or equal to the width W1 of the cover panel 2, or less than the width W1 of the cover panel 2, but it is preferable that it be greater than or equal to the width W1 of the cover panel 2. In this case, maintenance of the display 15 can be performed across the entire surface of the display 15. Furthermore, in this case, compared to the case where a dummy panel can be placed on only one side of the cover panel 2, the width W3 of the first dummy panel 11a and the width W4 of the second dummy panel 11b can be made narrower than the width of such a dummy panel. As a result, the first dummy panel 11a and the second dummy panel 11b can be easily manufactured and opened and closed, and the space required in front of them (on the opposite side of the rail 4 from the first dummy panel 11a and the second dummy panel 11b) for opening and closing can be reduced.

[0058] The ratio R of the total width W to the width W1 of the cover panel 2 is preferably 2.5 or more, more preferably 2 or more. However, the ratio R is preferably 3 or less, more preferably 2.5 or less.

[0059] <Dummy upper clamp component> From the viewpoint of improving appearance, it is preferable that the upper retaining dummy member 17a is positioned on the extension line of the upper retaining member 16 when the first dummy panel 11a is positioned to the left of the cover panel 2 along the rail 4. From the viewpoint of improving appearance, it is preferable that the upper retaining dummy member 17b is positioned on the extension of the upper retaining member 16 when the second dummy panel 11b is positioned to the right of the cover panel 2 along the rail 4.

[0060] The materials constituting the upper pressing dummy members 17a and 17b may be the same material as the upper pressing member 17 or different materials, but from the viewpoint of improving appearance, it is preferable that they be made of the same material.

[0061] <Lower frame dummy component> From the viewpoint of improving appearance, it is preferable that the lower frame dummy member 18a is positioned on the extension of the lower frame member 7 when the first dummy panel 11a is positioned to the left of the cover panel 2 along the rail 4. From the viewpoint of improving appearance, it is preferable that the lower frame dummy member 18b is positioned on the extension of the lower frame member 7 when the second dummy panel 11b is positioned to the right of the cover panel 2 along the rail 4.

[0062] The materials constituting the lower frame dummy members 18a and 18b may be the same material as the lower frame member 7 or different materials, but from the viewpoint of improving appearance, it is preferable that they be made of the same material.

[0063] <<Second Embodiment>> Next, a second embodiment of the display system of this disclosure will be described with reference to Figures 7 and 8. The display system 200 shown in Figure 7 differs from the display system 100 of the first embodiment in that a panel suspension part 3 is used instead of a panel suspension part 5, and a rail 204 is used instead of a rail 4.

[0064] The panel suspension section 3 comprises a fixing section 3a fixed to the upper end of the cover panel 2, a pair of rollers 3c that rotate along the rail 4, and a connecting section 3b that connects the fixing section 3a and the rollers 3c. Examples of materials that make up the fixing part 3a and the connecting part 3b include metals such as aluminum and iron. Examples of materials that make up the roller 3c include rubber and resin.

[0065] The panel suspension section 3 may consist of one or multiple sections, but it is preferable that it consists of multiple sections. In this case, even if the cover panel 2 is heated and expands by the display 15, it is possible to increase the distance between adjacent panel suspension sections 3, thereby absorbing the lateral expansion of the cover panel 2 (width direction, i.e., left-right direction D2) and suppressing the warping of the cover panel 2. The fixing portion 3a of the panel suspension portion 3 is preferably firmly fixed to the cover panel 2 with adhesive or screws.

[0066] The rail 204 includes a rail support portion 4a, a projection portion 4b, a connecting portion 4c that connects the rail support portion 4a and the upper pressing member 16 of the rail 4, and a projection portion 4d that protrudes from the lower end of the upper pressing member 16 toward the projection portion 4b of the rail 4. A slit is formed between the projection portion 4b and the projection portion 4d for the connecting portion 3b of the panel suspension portion 3 to pass through. The rollers 3c of the panel suspension section 3 are positioned on the protrusions 4b and 4d. Because the panel suspension section 3 of the display system 200 is equipped with rollers 3c, the cover panel 2 can be slid more smoothly than in the display system 100. Also, because the panel suspension section 3 is equipped with a pair of rollers 3c, the cover panel 2 can be positioned vertically and parallel to the surface of the display 15.

[0067] This embodiment is not limited to the first and second embodiments described above. For example, if there is a gap between the first dummy panel 11a and the side wall 9a, or between the second dummy panel 11b and the side wall 9b, dummy panels 12a and 12b may be placed, respectively, as shown in the display system 300 in Figure 10. The dummy panels 12a and 12b may be attached to the side walls 9a and 9b, or to the ceiling 1. Since the dummy panels 12a and 12b do not need to be removed, they may be fixed to the side walls 9a and 9b or the ceiling 1.

[0068] Furthermore, in the first and second embodiments described above, the upper pressing member 16 is fixed to the ceiling 1 and separated from the rail 4. However, as shown in Figure 9, the upper pressing member 16 and the rail support portion 4a of the rail 4 may be connected by a connecting portion 4c. Here, the connecting portion 4c may or may not be fixed to the ceiling 1.

[0069] Furthermore, in the first embodiment described above, the sliding material 6 is fixed on the protruding portion 4b of the rail 4, but another sliding material 6 may be fixed to the lower end of the projection 5a so as to contact the sliding material 6 on the protruding portion 4b.

[0070] In the first and second embodiments described above, the display systems 100 and 200 include a first dummy panel 11a and a second dummy panel 11b, but the display system of this disclosure does not necessarily have to include a first dummy panel 11a and a second dummy panel 11b. In this case, the cover panel 2 can be freely slid in the left-right direction D2. [Examples]

[0071] The present disclosure will be described in detail below with reference to examples, but the present disclosure is not limited to these examples.

[0072] (Example 1) An LED display measuring 1.8m wide and 1m high was installed on the main wall, and a furring wall made of 12mm thick plywood was installed opposite the main wall as an auxiliary wall. An opening measuring 1804mm x 1004mm was formed in the furring wall, and the LED display was embedded so that there was a 2mm gap between the opening in the furring wall and the display. At this time, a black sheet was applied to the surface of the furring wall opposite the main wall. A transparent acrylic sheet measuring 1995mm in width, 2.4m in height, and 5mm in thickness was prepared, and a light-transmitting decorative film was applied to the surface of this acrylic sheet to create a cover panel. Next, 20 acrylic resin protrusions were prepared. Each protrusion was made of a flat plate-like material measuring 95 mm in width, 50 mm in length, and 15 mm in thickness. The protrusions were attached to the upper edge of the cover panel using polymerization adhesive. The 20 protrusions were attached to the cover panel so that there was a 5 mm gap between adjacent protrusions. At this time, the sides of adjacent protrusions were left gapped and not bonded together. The bottom surface of each protrusion (a 95 mm x 15 mm surface) was polished to a flat surface. Meanwhile, a baked-on painted iron rail was prepared. The rail consisted of a rail support section and a protruding section, and the length of the rail was set to 4m. On the other hand, a 1mm thick polyethylene plate was prepared as a sliding material, and this polyethylene plate was attached to the protruding section of the rail. The rail support section of the rail was then fixed to the false wall. At this time, the rail was positioned parallel to the floor surface at a height of 2380mm from the floor surface. Next, the lower surface of the protrusion fixed to the cover panel was brought into contact with a polyethylene board, and the cover panel was suspended from the rail. At this time, a 2 mm gap was left between the display and the cover panel. Next, a strip-shaped upper retaining member was installed in front of the rail on the ceiling to prevent the cover panel from coming loose and falling. The upper retaining member had a length of 2m in the left-right direction (D2) and a length of 5cm in the up-down direction (D1). The upper retaining member was made of aluminum. Furthermore, a lower frame member was installed on the floor surface beneath the cover panel. The lower frame member consisted of a strip-shaped lower frame support section extending parallel to the rail and a pair of side wall sections extending toward the ceiling from both edges of the lower frame support section. The lower end of the cover panel was positioned between the pair of side wall sections to prevent the cover panel from moving back and forth. The length of the lower frame member in the left-right direction D2 was 2m, and the length of the side wall section in the up-down direction D1 was 5cm. The material of the lower frame member was aluminum. At the same time, a gap of 10mm was left between the lower frame support section and the cover panel to prevent contact with the lower frame support section even if the cover panel expanded. Furthermore, two dummy panels made of acrylic sheet measuring 1m wide, 2.4m high, and 10mm thick were prepared, and hinges were attached to the upper and lower edges of one side of each dummy panel. The dummy panels were then placed on either side of the cover panel, and the hinges were fixed to the false wall to form a door. In addition, a push latch was installed on the back of the edge of the dummy panel on the cover panel side, so that the dummy panel would open when pushed. An upper-pressing dummy member was attached to the top of the dummy panel, and a lower-frame dummy member was attached to the bottom, matching the design with the cover panel. Specifically, the upper-pressing dummy member was positioned on the extension of the upper-pressing member of the cover panel, and the color of the upper-pressing dummy member was the same as the color of the upper-pressing member of the cover panel. The lower-frame dummy member was positioned on the extension of the lower-frame member of the cover panel, and the color of the lower-frame dummy member was the same as the color of the lower-frame member of the cover panel. This is how the display system was created. With the display system thus constructed, the dummy panel can be opened by rotating it around an axis passing through the side edge of the dummy panel furthest from the cover panel using two hinges, allowing the cover panel to slide sideways and expose the surface of the LED display. This makes it possible to perform maintenance such as repairs on the LED display using the above display system. [Explanation of Symbols]
