2、控制器中。目前，大部分异步显示屏采用的是8位或16位的微控制器，由于受到微处理器的处理速度、体系架构、寻址范围、外围接口资源等诸多限制，已难以在要求显示较多像素、显示内容帧频较高、动态显示效果复杂的情况下得到良好的动态视觉效果。LED显示屏控制系统性能良好，工作稳定可靠，易于维护升级，具有很高的性价比。关键词：LED；数据传输；信息发布系统；单片机AbstractLED panel systems gains rapid development in the design, machine and application from nine-rites
3、ages. It went thorn from single color and two colors to image LED panel. As a high technology production, LED panel can realize real time and sequential displaying textile, granitic and images. LED panel has many special feature such as high reliability、long life、high performance
4、、low cost、and more important high acclimatization. Moreover, with the technique of color p Anne perfect increasingly,LED panel is widely used in many fields. The core technique for a LED panel is mainly centralized on its controlled. The majority of asynchronous display panel use
