Software and hardware design and implementation of LED display system of stadium big screen

摘要

This paper introduced main ideas of hardware and software design and specific methods of realization of LED screen display system in detail. Extract computer CRT digital video by and convert signal from video signal to the LED display CRT signal by circuit implementation, and driving circuits receive LED display signals after conversion, and assign them to LED dot matrix corresponding to pixel, and drive the LED screen to display in real time. We give specific compacted method of using software to realize interactive function of big screen score display by AUTHERWARE multimedia production. Through the practical engineering application, the system showed that it has simple structure, easy maintenance, detection and price ratio is high, and has a strong market competitive power.
