Description

[Technical Field]

[0001] The present invention relates to a display device and an installation method thereof. [Background technology]

[0002] Conventionally, glass or resin panels are installed to protect the surface of monitors such as LEDs and LCDs. The panels are sometimes colored to improve the contrast of the screen displayed on the monitor or to reduce glare, and decorative panels are sometimes installed on the surface of the panel. When the monitor size becomes large, it can be difficult to cover the entire screen with a single panel. Patent Document 1 discloses a method of connecting multiple panels for installation. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2021-188414 Summary of the Invention [Problem to be solved by the invention]

[0004] Covering a large-screen monitor with a large plastic panel presents problems such as poor maintenance, such as poor removal, and the panel's horizontal deformation when it expands. Dividing the panel into multiple pieces and reducing its horizontal dimensions makes horizontal deformation negligible. However, when smoked panels are used, the light leaking through the gaps between the panels is brighter than the light transmitted through the panel, resulting in dazzling light. Furthermore, when smoked panels are fastened together with adhesive or caulking, or connected with metal fittings, the smoked panels become difficult to remove individually. Furthermore, when smoked panels are inserted into H-shaped metal fittings, the width of the fittings increases, increasing the area of ​​the image that is hidden. Furthermore, when smoked panels are connected together with adhesive or metal fittings, they may be pushed up and deformed when they expand.

[0005] The present invention aims to provide a display device that protects the monitor surface with multiple adjacent smoked panels, that suppresses dazzling light from leaking through gaps between adjacent smoked panels, that is easy to maintain, and that is less likely to deform laterally even if the smoked panels expand. Another object of the present invention is to provide an installation method for the display device. [Means for solving the problem]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the drawings are schematic, and for example, the relationship between thickness and planar dimensions, and the thickness ratio of each layer may differ from the actual ones. Furthermore, the embodiments shown below are merely examples of configurations that embody the technical concept of the present invention, and the technical concept of the present invention is not limited to the materials, shapes, structures, etc. of the components described below.

[0010] <Display device> FIG. 1 is a front view schematically illustrating a state in which a display device 10 according to the present embodiment is installed on a wall 4, and FIG. 2 is a cross-sectional view schematically illustrating a state in which the display device 10 is installed on the wall 4, which is also a cross-sectional view of the display device 10 shown in FIG. 1. The display device 10 includes a plurality of adjacent smoked panels 1 and a monitor 2 having an image display unit. Gaps exist between the plurality of adjacent smoked panels 1. In the display device 10, a dimming area 3 is provided on the monitor 2 side of the gap. This display device 10 suppresses the leakage of dazzling light from the gaps between adjacent smoked panels 1, is easy to maintain, and is less likely to deform laterally even if the smoked panel 1 expands. Note that the installation location of the display device is not limited to a wall, and it may be disposed as part of a vehicle component, a home appliance, or the like.

[0011] (Smoke panel) The plurality of smoke panels 1 improve the contrast and reduce glare of the screen displayed on the monitor 2. In this specification, the smoke panel means a colored transparent panel with a transmittance of 40% or less.

[0012] The plurality of smoke panels 1 may be colored smoke panels, or may be colorless and transparent panels (colorless and transparent resin panels or glass) with a colored transparent film such as a smoke film or a light-transmitting decorative film attached. The shape of the smoke panels is not particularly limited and may be determined according to the shape of the monitor.

[0013] The smoke panels 1 include, for example, a resin and a pigment. Examples of the resin include acrylic resin, PET resin, vinyl chloride resin, polycarbonate resin, nylon resin, polyethylene resin, and polypropylene resin. Examples of the pigment include carbon black, iron oxide, chromium oxide, ultramarine blue, phthalocyanine pigment, naphthol pigment, azo pigment, cadmium pigment, and anthraquinone pigment.

[0014] When the smoke panel has a light-transmitting decorative film, the light-transmitting decorative film may be provided on the surface of the smoke panel opposite the monitor, or on the surface of the smoke panel facing the monitor. The light-transmitting decorative film includes at least a printing layer on which a pattern is printed. The printing layer is a layer that expresses the color and pattern of the light-transmitting decorative film. The printing layer can be formed by, for example, screen printing, inkjet printing, gravure printing, or offset printing. The structure of the light-transmitting decorative film is not particularly limited as long as it is transparent to visible light and allows the image displayed on the image display unit of the monitor to be viewed through the light-transmitting decorative film.

[0015] The transmittance of the smoke panel 1 may be 3 to 40%. The transmittance of the smoke panel 1 may be 15% or more and 30% or less. The transmittance of the smoke panel 1 is total light transmittance, and can be measured by a spectrometer.

[0016] The thickness of the smoke panel 1 may be 1 mm or more, or 5 mm or more, or 10 mm or less, or 5 mm or less. The thinner the smoke panel 1, the lighter the smoke panel 1 is, and therefore the easier it is to handle the smoke panel 1. The thicker the smoke panel 1, the less likely it is to deform.

[0017] The width of the surface of the smoke panel 1 is preferably 1000 mm or less. By making the width of the surface of the smoke panel 1 1000 mm or less, the smoke panel 1 is less likely to warp in the width direction and the amount of expansion is also small, which improves the ease of removal and installation of the smoke panel 1.

[0018] There are gaps between the smoke panels 1. By intentionally leaving gaps between the smoke panels 1, the smoke panels 1 are not connected to each other, so they can be removed individually, making maintenance easier. In addition, by intentionally leaving gaps between the smoke panels 1, the smoke panels 1 are prevented from being pushed up when they expand, and deformation of the smoke panels 1 can be suppressed.

[0019] The width of the gap between the smoke panels 1 may be large enough to prevent the smoke panels 1 from being pushed up when they expand. If the gap is zero when the smoke panels 1 are at their most expanded, they can be prevented from being pushed up.

[0020] The smoke panel 1 is fixed to a raised wall 5 by a joint 6 such as a bolt. The smoke panel may be fixed directly to the wall or by using a metal anchor. The smoke panel may be fixed to the wall by joints at multiple points on the smoke panel so that the smoke panel does not move at all. Alternatively, the smoke panel may be fixed to the wall by a joint at only one point on the smoke panel so that the smoke panel can rotate, etc.

[0021] The number of smoke panels is not limited to two and may be adjusted according to the size of the monitor.

[0022] (Monitor) The monitor 2 has an image display unit. The monitor 2 is a light-emitting device such as a liquid crystal monitor, an organic EL monitor, an LED monitor, or a projection monitor. The monitor 2 may have a light source inside. The monitor 2 may have a bezel (frame), and the bezel may be a dimming area 3. The material of the bezel may be a resin such as polycarbonate or ABS resin; or a metal such as aluminum or stainless steel. The monitor 2 is fixed to a wall 4, for example. The monitor 2 may be composed of a single monitor or multiple monitors.

[0023] (Dim area) The display device 10 has a dimming area 3 between the monitor 2 and the gap. By providing the dimming area 3 in the display device 10, it is possible to prevent light from leaking out from the gap when a viewer looks at the monitor 2 through the gap.

[0024] The dimming area 3 may be formed of, for example, a light-shielding material. Examples of light-shielding materials include metals such as iron, aluminum, and copper; resins such as acrylic resin, vinyl chloride resin, PET resin, polyethylene resin, and polypropylene resin; and wood. The dimming area 3 may be formed of a light-shielding material such as a light-shielding tape made of vinyl chloride resin, acrylic resin, PET resin, polyethylene resin, or polypropylene resin, or may be a bezel of the monitor 2, a location where the LED of the image display unit of the monitor 2 does not emit light, or may be formed by displaying the image displayed by the monitor 2 in black or gray.

[0025] When the dimming area 3 is formed from a light-shielding material, it is preferable that the thickness of the dimming area 3 (light-shielding material) be 25 μm or more and 1 mm or less, from the viewpoint of making the dimming area 3 difficult to see when viewing the monitor 2 from an angle relative to the surface of the monitor 2.

[0026] When the dimming area 3 is formed of a light-blocking material, in one embodiment, the dimming area 3 is provided on the surface of the monitor 2 facing the smoked panel 1, as in the display device 10 shown in Fig. 1. The dimming area 3 may be provided on the surface of the monitor 2 via a removable adhesive. By providing the dimming area 3 on the surface of the monitor 2 facing the smoked panel 1, it becomes possible to remove the smoked panel 1 independently without removing the dimming area 3, improving maintainability.

[0027] In another embodiment, the dimming area 3 is provided on the surface of the smoked panel 1 facing the monitor 2, as in the display device 20 shown in Fig. 3. The dimming area 3 is adhered to only one side of the smoked panel 1, for example, via an adhesive. By providing the dimming area 3 on the surface of the smoked panel 1 facing the monitor 2, the dimming area 3 becomes difficult to see when the monitor 2 is viewed from an angle relative to the surface of the monitor 2. Furthermore, by adhering the dimming area 3 to only one side of the panel, the panels can be removed one by one, starting from the edge.

[0028] In another embodiment, the dimming area 3 may be provided without being adhered to either the surface of the monitor 2 facing the smoke panel 1 or the surface of the smoke panel 1 facing the monitor 2. In this case, the dimming area 3 is fixed to a false wall 5 or the like. By providing the dimming area 3 without being adhered to either the surface of the monitor 2 facing the smoke panel 1 or the surface of the smoke panel 1 facing the monitor 2, it becomes possible to remove the smoke panel 1 independently without removing the dimming area 3. Furthermore, by attaching the dimming area 3 to the smoke panel 1 side, the dimming area 3 becomes difficult to see when viewing the monitor 2 from an oblique angle.

[0029] The color of the dimming area 3 may be black or gray so that the dimming area 3 is less noticeable when the monitor is off.

[0030] The width of the dimming area 3 need only be equal to or greater than the width of the gap. From the viewpoint of more reliably reducing light leakage from the gap, the width of the dimming area 3 is preferably equal to or greater than the width of the gap when the smoke panel 1 is at its narrowest. From the viewpoint of making the dimming area 3 difficult to see when the monitor 2 is viewed from an angle relative to the surface of the monitor 2, the width of the dimming area 3 is preferably equal to or less than 5 mm.

[0031] From the viewpoint of better preventing dazzling light from leaking, it is preferable that the transmittance of the light-reducing area 3 is lower than the transmittance of the smoke panel 1. The transmittance of the light-reducing area 3 can be measured in the same manner as the transmittance of the smoke panel 1.

[0032] <How to install the display device> Another embodiment of the present invention is a method for installing a display device. The method includes the steps of: fixing a monitor; installing a plurality of colored smoke panels on the surface (display surface) opposite the surface to which the monitor is fixed (the surface on which the monitor is fixed) with gaps between the plurality of smoke panels; and providing a dimming area between the monitor and the gaps. This method for installing a display device protects the monitor surface with a plurality of smoke panels, while suppressing light leakage from the gaps between the plurality of smoke panels, making the display device easy to maintain, and suppressing deformation of the smoke panels even if they expand.

[0033] In the method for installing a display device, the monitor or the plurality of smoke panels may be fixed so that the joint for fixing the monitor is aligned with the position of the gap between the plurality of smoke panels. By aligning the joint for fixing the monitor with the position of the gap between the plurality of smoke panels, a dimming area is provided above the joint for the monitor, making it difficult to see the joint for the monitor.

[0034] In the display device installation method, the step of providing a dimming area may be a step of providing a dimming area on the surface of the monitor facing the smoke panel, or a step of providing a dimming area on the surface of the smoke panel facing the monitor. By providing a dimming area on the surface of the monitor facing the smoke panel, the smoke panel can be removed independently without removing the dimming area, improving maintainability. By providing a dimming area on the surface of the monitor facing the smoke panel, the dimming area becomes difficult to see when the monitor is viewed from an angle relative to the monitor surface. [Example]

[0035] Examples of the present invention will be described below, but the present invention is not limited to the following examples.

[0036] Example 1 Fig. 4(a) shows a front view of the display device produced in Example 1, and Fig. 4(b) shows a cross-sectional view in the width direction. The specific production of the display device is as follows.

[0037] First, we installed two 500mm square LED panels (32 in Figure 4) vertically and three horizontally on a wall (34 in Figure 4) with a ceiling height of 2100mm, and then installed an LED monitor measuring 1500mm wide and 1000mm high.The LED monitor was installed so that it would fit inside a false wall (35 in Figure 4) that was 2mm thicker than the surface of the LED monitor.

[0038] We prepared black PET light-shielding tape (transmittance 0%, 33 in Figure 4) that was 3 mm wide, 0.05 mm thick, and 1500 mm long, and attached it to the connection points between the LED monitors.

[0039] Next, smoke panels (31 in Figure 4) measuring 500 mm and 498 mm wide, 5 mm thick, and 2000 mm long were prepared at 25°C. Rectangular through-holes (37 in Figure 4) were drilled at both ends of the top of each smoke panel, and a circular through-hole was drilled in the center of the top. The smoke panels were made of acrylic with a transmittance of 18%. The 498 mm wide smoke panel was fixed to the wall with a screw (36 in Figure 4) through the through-hole in the center of the top, so that it was centered over the LED monitor. Two 500 mm wide smoke panels were similarly attached to the wall, with a 2 mm gap between them on either side of the 498 mm wide smoke panel. This installation aligned the center of the gap between the smoke panels with the center of the black light-blocking tape. A 1 mm gap was left on both ends of the three panels, and the wall was 5 mm thick. The distance from the surface of the light-shielding tape to the surface of the LED monitor side of the smoke panel was 2 mm. The rectangular through-holes at both ends of the top of the smoke panel were supported by a rotating ring attached to the wall, so that the position of the smoke panel did not move and the expansion and contraction of the smoke panel in the width direction was not prevented, and the display device was fabricated. A metal plate (not shown) was placed in front of the panel to prevent the panel from floating up. The metal plate did not come into contact with the panel, and a gap of 10 mm was provided below the panel.

[0040] When the LED monitor was turned on, the surface temperature of the panel reached a maximum of 40°C. By providing gaps between the smoked panels, the smoked panels were not pushed up even when they expanded, and large deformation of the smoked panels was suppressed. Although the smoked panels warped vertically, causing a 5mm distance between the display and the panel, no dazzling light leaked from the gaps between the panels. Furthermore, because the smoked panels in the manufactured display device were not connected to each other, they could be removed individually, making them easy to maintain. [Explanation of symbols]
