Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a large display device.

[Conventional technology]

A large-sized display device, for example, has light emitting display elements arranged in a plurality of spaces divided into a grid pattern, and also includes separators that partition the space into a grid pattern, a structure that supports the light emitting display elements, and the like. This large display device is attached to the wall or ceiling of a building.

[Problem to be solved by the invention]

The large-sized display device is a single unit that can be attached to a building or the like, so there is a problem in that the installation cost is high.

Furthermore, since the entire device is a single unit, it is difficult to install it in accordance with the size and shape of the object to which it is attached.

Therefore, it is an object of the present invention to provide a large-sized display device that can reduce costs.

[Means to solve the problem]

In order to solve the above problems, a large-sized display device according to the present invention is characterized in that a plurality of light emitting display elements are installed in a space divided into a grid pattern by the base material of a building.

[For production]

Since the large-sized display device according to the present invention utilizes architectural components, that is, the base material of the building as part of the display structure, the cost of the display can be significantly reduced.

〔Example〕

Hereinafter, the present invention will be explained in detail with reference to the drawings showing embodiments thereof.

1 to 3 show one of the large-sized display devices according to the present invention.
Represents an example. Figure 1 (al) is a cross section of a part of the system seen from the side, and Figure 1 (b) is a further enlarged view of that part. Figure 2 is a conceptual diagram of the system, and Figure 3 is a cross section of the system seen from the back. FIG.

As seen in these figures, this large display device 100 is
A plurality (many) of light emitting display elements 101... are installed in a space 130... partitioned into a grid pattern by base materials 11..., 12... on the ceiling. It is preferable that the light emitting display elements 101 are closely attached to the spaces 130 to form the display section 110. ing. The lamp 102 is R (red), G
It is designed to emit light of three primary colors, green (green) and blue (B), either singly or in combination of two or more. The diffusion panel 103 is made of, for example, a milky white plate or an acrylic plate with a textured surface 103a, and the reflection plate 104
The reflector plate 104 is attached to the front opening of the reflector plate 104 by curling or the like. The reflector 104 is not particularly limited, but rather than being a device that significantly increases the luminous intensity in a specific direction, such as those used in spotlights, the reflector 104 is used to direct all the light emitted from the lamp toward the front with high efficiency and high uniformity. It is preferable to use something that can diffuse light, such as a high-breadth reflector, and the light distribution characteristics of the light emitting display element 101 are as shown in FIG.
As shown in al, the maximum luminous intensity M is not at the center of the optical axis but at a position shifted by a certain angle α from the center of the optical axis. Thereby, a large display surface can be obtained without reducing brightness. When the diffusion panel 103 is attached to the front of the light emitting display element 101, the direct light from the lamp 102 and the light reflected by the reflection plate 104 are diffused and irradiated, so that the light distribution can be highly uniform. .

The base materials 11..., 12... are arranged in a lattice shape, and suspended horizontally by the suspension devices 1.... The base materials 11 are main bars, and are arranged in parallel and apart from each other. The base materials 12 are crossbars arranged parallel or at right angles between the base materials 11.

As shown in FIG. 4, the hanging device 1 includes a hanging bolt 4 whose upper end is screwed into an insert 3 embedded in a ceiling slab 2 and hangs down, and a nut 5.5 at the lower end of the bolt 4. It consists of a hanger 6, which is attached using a hanger, and an attachment piece 7. The hanging device l may be directly attached to the ceiling slab 2, but this large display device 1
In order to maintain the 00 from the rear, a scaffold called a catwalk that can withstand a considerable load may be provided and attached to this scaffold. By installing such a scaffold, when the large display device 100 cannot be maintained from the front (from the bottom when installed on the ceiling), it can be easily maintained from the back.

The lower end portions of the suspension devices 1 are coupled to appropriate locations on the base materials 11, 12, and so on. Base material 11゜1
2 are so-called T-bars each having an inverted letter-shaped cross section, and upper end portions 11a and 12a are thick like rails. The hanger 6 is attached by sandwiching the upper ends 11a and 12a with the piece 7 and tightening with bolts and nuts, thereby firmly suspending the base materials 11 and 12.

In each of the square spaces 130 (lattice) formed by the base materials 11 . . . , 12 . . . , light emitting display elements 101 . That is, the front edge of the light emitting display element 101... is placed on each flange llb..., 12b... of the base material 11..., 12.... If the light-emitting display element 101 is installed by dropping it in this way, construction is easy and maintenance is easy. In this case, for safety, each light emitting display element 1
01, it is best to take measures to prevent falling. For example, S.U.
One end of the fall prevention wire 14 made of S''1 etc. is attached to the hook 15, passed around the hanging bolt 4, passed through the ring of the hook 15, and dropped onto the stud 33 provided on the back of the light emitting display element 101. The annular portion at the other end of the prevention wire 14 is fitted, and the nut 34 is used to secure it.

The large display device according to the present invention performs display in the following manner, for example, but is not limited thereto.

Data is created using the input device 9. The input device 9 includes, for example, a personal computer, a CRT, and a keyboard. Data is transmitted from input device 9 to control device 8 via control line 41 . Based on the data, the control device 8 sends, for example, signals of at least one of the three primary colors of light, R, G, B, R+B, R+G, B+G, and R+B+G to the control/lighting block via the control line 41. Send to 31. The control/lighting block 31 is, for example, an inverter type ballast, and controls the display of the light emitting display element 101 based on transmission from the control device 8 . As a result, a pattern as shown in FIG. 5(a), (b), or (C), for example, is displayed. Each light emitting display element 101 is a dot unit, and can display characters, figures, images, etc.

Note that this invention is not limited to the above embodiments. The large-sized display device of the present invention may be installed not only on the ceiling of a building but also on internal and external walls.

In addition, in the above example, the light-emitting display element was installed by dropping it into the ceiling base material, but the base material is simply used as a separator, and the light-emitting display element is installed in a structure that can withstand considerable loads such as a ceiling slab or steel frame. It may also be supported directly on the material. Furthermore, the light-emitting display element does not need to emit all three primary colors of light; it may exhibit one or more colors as long as it can display. However, if the three primary colors of light are emitted arbitrarily, it is convenient for displaying color images. The shape of the display section of the large-sized display device does not need to be square, and may be any other suitable shape, for example, a shape that matches the surface shape of the building in which it is installed. According to this invention, the light-emitting display element, base material, etc. can be made into parts, and many types of large-sized display devices can be easily realized using a small number of parts and simply by changing the number of parts and the way they are combined as appropriate. be done.

〔Effect of the invention〕

Since the large display device according to the present invention is as described above, the cost can be reduced.
