Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a large-sized liquid crystal display comprising a large number of liquid crystal display panels, and more particularly to a large-sized liquid crystal display in which mutual electrical connection and installation of the liquid crystal display panels is easy.

BACKGROUND ART Conventionally, as a large-sized display, a display called Aurora Vision, which displays images using a large number of color cathode ray tubes, has been popularized. In this type of large display, there is a limit to the miniaturization of the color cathode ray tubes used to form one pixel, and the cathode ray tubes are placed at a certain distance from each other to avoid being affected by heat, etc. Therefore, the pixel area and pixel spacing are large, and a viewing distance of 60 m or more is required.

For this reason, various large-sized liquid crystal ice displays have been proposed that are constructed from a large number of liquid crystal display panels in order to reduce the pixel area and pixel spacing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a large-sized liquid crystal display, which is characterized by a connection structure between the liquid crystal display plates, has excellent assembly workability, and has a very small distance between the liquid crystal display plates.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a large liquid crystal display gray according to the present invention. This large-sized liquid crystal display gray includes a large number of liquid crystal display boards 1, and these liquid crystal display boards 1 are arranged at regular intervals on a large panel (not shown). Each liquid crystal display panel 1 consists of two opposing glass plates with liquid crystal sealed in them. Electrodes for displaying images are formed on the inner surface of each glass plate, and these electrodes extend from both sides. Terminal portions IA, IA (see FIG. 2) are formed by a plurality of extending terminals.

The beautiful liquid crystal display of the present invention includes each of the above-mentioned liquid crystal display boards 1
Terminal part IA of , IA is connected to terminal part I of the adjacent liquid crystal display board l
A, a conductive rubber 2 for connecting to IA, and a ninth conductor for attaching the large number of liquid crystal display boards 1 arranged above to a large panel (not shown) and electrically connecting each liquid crystal display board 1. It is equipped with a frame 3.

As shown in FIG. 3, the conductive rubber 2 is composed of two main bodies whose central portions protrude in a step-like manner, and a plurality of conductive plates 2B sandwiched between the two main bodies. . As shown in FIG. 2, this conductive rubber 2 is placed between adjacent liquid crystal display plates 1.1 with its central portion slightly protruding, and each of the above-mentioned liquid crystal display panels is placed on both tiers. One terminal portion IA of the plate 1 is connected by crimp. Therefore, in Figure 1,
Each horizontal liquid crystal display panel can be connected not only physically but also electrically.

The conductor frame 3 is formed in a lattice shape, and is attached to the central part of the main body of the conductive rubber 2 and the edges of each liquid crystal display board 1, and is attached to a panel (not shown) in a pressed state. Therefore, each of the liquid crystal display panels 1 is held on the panel by the conductor frame 3 and electrically connected to each other via the conductor frame 3 and the conductive rubber 2.

As is clear from the above description, according to the present invention, each terminal portion of adjacent liquid crystal display boards is physically and electrically connected via conductive rubber, and a large number of liquid crystal display boards are connected to each other by a conductor frame. Since the conductive frame and conductive rubber are held on top and electrically connected, a large LCD display can be easily assembled, and each LCD panel can be placed close to each other. As a result, very clear images can be obtained.
