DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel display device for installing an upper portion. More specifically, the present invention relates to a display device suitable for being installed in an upper part such as an arcade or a ceiling of an indoor stadium.

[0002]

2. Description of the Related Art Conventionally, as a large-sized image display device, there is a device in which a small non-deflection CRT or a discharge tube in which several pixels are integrated as a light-emitting element is arranged vertically and horizontally.

[0003]

However, in the above-mentioned conventional large-sized image display device, the weight is large. In order to use the large-sized image display device on a ceiling or the like and use it as an upper-installation display device that can be viewed from below, It is necessary that the holding member has sufficient strength, so that the weight of the holding member itself increases, and it is unsuitable as a display device for installing the upper part.

Therefore, if a light-emitting diode is used as a light-emitting element, the weight can be reduced, but a printed circuit board for supplying current and signals, a frame for supporting these, and the like are required, and it cannot be said that the weight is sufficiently reduced. In addition, since the printed circuit board blocks light, there is a problem that separate lighting is required even in the daytime. Furthermore, there is a problem that it is difficult to attach or detach the small screen.

In addition, the plug-in type collective lamp can be easily attached and detached for each small screen, but there is a problem that there is a risk of falling.

Accordingly, an object of the present invention is to provide an upper-mounted display device which is lightweight, has no light-shielding properties, and is suitable for use in arcades, ceiling surfaces of indoor stadiums, and the like.

[0007]

In order to solve the above-mentioned problems, a display device for installing an upper portion according to the present invention comprises a grid-like structure in which a vertical power supply wire and a horizontal power supply wire are insulated from each other. In this structure, the leads of the light emitting diode are connected to each other at the intersections of the above-mentioned vertical and horizontal wires.

Therefore, in the display device for installing the upper part according to the present invention, since the main components are only the electric wire for power supply and the light emitting diode, it can be formed extremely light and no printed circuit board is required. Therefore, it is possible to provide a display device which is extremely suitable as a display device installed in an upper portion such as an arcade or a ceiling of an indoor stadium without interrupting daylight.
