It is about an all-optical display device that is used in many environments and places.

A visual display device is used to effectively transmit various changed product information. In addition, when a large place and a crowd are crowded, a large display device is required to transmit a lot of information at the same time.

However, in high-rise cities, display devices are installed on the walls of buildings, and the visual field is obscured by the size of the space to be installed. As the installation of display devices in buildings is subject to physical and design constraints, it is an effective transmission device using vision. It was difficult to use as.

A transparent plate is attached to the front surface of the case, and a light shield 31 that prevents direct sunlight coming to the display element is attached to the matrix.

A device driving circuit is attached to the rear transparent plate 37 to output a control signal. For example, the horizontal controller 50 outputs a clock and the vertical controller 40 outputs R, G, and B data. 32 are arranged on the matrix and wires are connected to each socket vertically 33 and horizontally 34 to supply power and data signals (see FIGS. 2 and 23).

On the transparent plate 62 bonded to the plug 63, a plurality of display elements are arranged in a matrix (see FIGS. 10 and 15) and are configured to see between display elements (see FIG. 6), and the plug 63 Is connected to the socket 32, and the plug includes a display element driving circuit 64 to latch, for example, R, G, and B data signals and output display element driving data (see FIG. 22).

Therefore, when the rear transparent plate 39, the display plate 60, and the front transparent plate 36 are lined up in a row, the device becomes a perspective 39 through the transparent plate, and the display element 61 wired to the transparent plate. ), The screen displays characters or images (see FIG. 3), and when the rear transparent plate 37 is removed from the case 35, all elements and parts can be easily operated behind the device (20). See also).

In addition, the easy removal of the rear transparent plate from the case facilitates the use of the display device on large structures. For example, the rear transparent plate is attached after checking the equipment or installing the case on the structure. It is intended to be used in environments and places.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a reference diagram showing an embodiment of the overall configuration of the present invention. The apparatus consists of an image transmission system 10 and an image display system 20. The image transmission system 10 is expressed in the VTR 11, the LDP 12, the camera 13, the computer image 14, and the like. The video signal is selected from the video editing device 15 and output through the video transmitting device 16. The signal received from the video receiving device 21 of the video display system 20 is output from the display device controller 22. Images are displayed on a plurality of display devices 30 that are digitally signaled and supplied and arranged.
