会展用大屏幕LED显示系统的设计与实现

摘要

Currently in the field of electronic technology, semiconductor technology more widely, LED display is a typical semiconductor technology and is widely used. LED display system consists of hardware and software systems , under the control of the input signal by a complete storage and updating of data, the screen display, animation treatment. The paper designed and implemented a simple exhibition with a large-screen LED display system, using the system's hardware and software design combined with a simple external circuit to meet the use of large-screen LED enhances the universality of LED large screen. The practical application shows that the design is stable and reliable , with a strong practical.%LED显示系统是半导体技术的一种典型且广泛的应用。文中设计了一种适合会展用的LED显示系统，该显示系统分为硬件系统和软件系统，在由输入信号的控制下，完成数据的储存与更新、画面显示、动画处理等功能。设计的大屏幕LED显示系统，只需要辅以简单的外围电路即可满足会展时大屏幕LED的使用，增强了LED大屏幕的普适性。实际应用表明该设计稳定可靠，具有较强的实用性。
