Control System Design For Colorized LED Flat Panel Display Based On CPLD

In recent years, large screen display system is widely used with the development of display device and technology. Because LED large screen display system has characteristics of small cubage, high brightness, low weight, planar architecture, high precision display location and so on, it takes a large proportion of application of large screen display. It has become an integrant part of science and technology and greatly stimulate the development of apparatus and devices, so the research in this field attract much more attention.The research of this subject is set up to overcome the disadvantages of existing control system, introduce a new scheme of colorized LED plat panel display based on CPLD, it also relies on the abundant and flexible characteristic of embedded system to accomplish the function of control and data processing, making the system more flexible and easy to use.According to the requirement of the project, the whole system is divided into several parts, the detail scheme of each part is introduced in detail. The optimum components are used by considering a lot of factors such as the requirement, the characteristic, cost, and the convenience of purchase. On the bases of adequate experiment and debugging, the system achieve the requirement. Every module function that the research involved has carried on systemic emulation and synthesis, they are proved to be correct.
