BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display unit device for constructing a large screen by mounting a plurality of display units each consisting of a plurality of display elements in a plurality of stages.

0003

2. Description of the Related Art For example, in outdoor events and broadcasts, display devices that combine multiple screens to form a large screen are sometimes used to display powerful images. In such a display device with a large screen, a plurality of display units constituting one screen are generally mounted on each shelf of a display unit device including a plurality of shelves. Here, the display unit used is one in which a plurality of display elements each having a light emitting element such as a light emitting diode are attached to a display unit main body at regular intervals in a grid pattern vertically and horizontally.

The display unit mounting device for mounting a plurality of display units needs to be constructed so that the display units do not fall out of the storage section to the front. As a conventional display unit mounting device for this purpose, there is one in which a panel having holes through which each display element of the display unit passes is provided on the front surface of the display unit device. Furthermore, there is also known a display unit mounting device in which a stopper is provided on the front surface of each shelf to prevent the display unit from jumping out.

[0005]

However, in the case of a display unit mounting device in which a panel is provided on the front surface with through holes for each display element on the front surface, there is a problem in that the weight becomes large.

On the other hand, in a display unit mounting device in which a stopper is provided on the front of each shelf to prevent the display unit from popping out, there is a possibility that the display unit may fall off to the front if the shelf board is distorted. The unit mounting device needs to be strong, which increases manufacturing costs and increases weight, making it difficult to move. Furthermore, the position of the display element is not constant when the display unit is attached, making it difficult to adjust the entire screen so that it forms a continuous surface.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a display unit that is relatively light in weight and that allows easy adjustment of the screen position of the display unit.
To provide a display unit device in which a display unit does not fall off.

[Configuration of the invention]

[0009]

[Means for Solving the Problems] The present invention provides a display unit in which a plurality of display elements are mounted on a display unit base with a plurality of display elements tilted forward and downward in a grid pattern at regular intervals, and mounted on a plurality of shelf boards. In a display unit device for configuring a screen by arranging a plurality of display units, one or more display units are positioned between the display elements to position the display unit on the front side where the screen is configured. A guide member is provided in at least one of the vertical direction and the horizontal direction.

0010

According to the present invention, one or more guide members are provided in at least one of the vertical and horizontal directions at a distance from the display element of the display unit on the front side where the screen is formed. Then, the display unit is inserted into the display unit device from the back side, and positioned by pushing the display unit into contact with the guide member to prevent the display unit from falling off to the front.
