Problems solved by technology

This method not only makes the display content relatively fixed, but also makes it difficult to replace or upgrade the system
[0006] In addition, the existing liquid crystal display module also has the following defects: high cost, low data transmission rate, no guarantee of data transmission security, and no special technical means to ensure the accuracy of data transmission; in addition, the existing Most of the liquid crystal display modules are driven by one drive circuit to display information on one display screen. To realize multi-screen display, multiple drive circuits are required to drive, and the cost is relatively high.

Abstract

The invention discloses a multi-display-screen parallel display system. The multi-display-screen parallel display system comprises a display driving circuit 1, n display control circuits 2 and n liquid crystal display screens 3. An A wireless receiving and transmitting module 4 is arranged on the display driving circuit 1, a B wireless receiving and transmitting module 5 is arranged on each display control circuit, and the A wireless receiving and transmitting module 4 and the B wireless receiving and transmitting modules 5 are wirelessly connected and have communication through a diffusion routing algorithm and a CSMA / CD protocol. The n display control circuits 2 and the n liquid crystal display screens 3 are correspondingly connected one to one. Because the display control circuits are arranged and the wireless receiving and transmitting modules are arranged on the display driving circuit and the display control circuits and have communication through the diffusion routing algorithm and the CSMA / CD protocol, wireless liquid crystal display is achieved, and the safety and the accuracy of liquid crystal display data transmission are guaranteed. The wireless liquid crystal display system is good in communication quality and low in requirement for hardware.

Description

technical field [0001] The invention relates to a multi-display parallel display system, which belongs to the technical field of liquid crystal display systems. Background technique [0002] The application of liquid crystal display module is more and more extensive. It is often used in communication terminals, various specifications of water meters, electric meters, gas meters, electronic scales, industrial instruments, PDAs, telephones, fax machines, instruments and meters, and medical equipment display screens. , home appliances, and liquid crystal instruments of automobiles and motorcycles, etc., can display numbers, characters, graphics, etc. [0003] Most of the existing liquid crystal display modules are wired through the interface, which can be roughly divided into two types: [0004] One is a liquid crystal display module with external data transmission. If long-distance transmission is to be realized through wired communication, not only is it difficult to wire mo...
