LED Three-Dimension Dynamic Display System Of Informationg With Single-Chip Microcomputer

The display technology of LED (Light Emitting Diodes) is a new modern technology synthesizing photo-electricity, computer and control etc. It combines closely with traditional advertising and becomes a new media instrument for propaganda, and is widely applied to the information displaying and advertising in public place, such as exhibition centre, financial market, stadium, airport, quay, station etc. The LED display system is composed of display module, controller and computer used to implement the characters inputting and the display mode selecting. The system can show Chinese and English as well as figure symbols appointed by users.Due to the diversities of the display mode and ideal visual feelings, LED display system is welcomed by users and becomes a new type of scientific product with high-speed development in recent years. Normally the LED display system is complicated and could be controlled nearby as well as the maintenance of the equipment is insufficient, thus the applications of LED display system receive a great restriction especially in remote control and synchronous transmission, so this technology needs further development and improvement.The LED displaying system of character symbols is studied in this paper. A detailed review is given to the actuality and developing trends of LED display screen, and a new structure plan on the LED display screen of three-dimension dynamic LED lattice controlled by microcomputer is presented, which aims at overcoming the problems in current display systems. Instructions and information can be input by simple and convenient man-machine interactive conversations, and the long-range control of display module can be realized, at the same time the display contents can be renewed at any moment and the omni-directional spatial stereoscopic display could be achieved. Theflow of software and the design plan of the circuit are given detailedly from the information picking-up on computer to the output of ultimate screen display. Further more, corresponding methods are discussed according to the specific technical difficulties of LED display system.
