摘要
本文给出了微机全画面映射ＬＥＤ显示屏的一种实现方法。以ＴＶＧＡ８９００显示适配器的接口技术为例，详细介绍了ＬＥＤ显示屏系统中颜色信号的提取、传输及处理过程，并列举了ＬＥＤ像点的几种驱动方式。最后，讨论了颜色校正、闪烁等实际问题。
In this paper,a design method of the full -picture-mapping LED video screen is presented for microcomputer.Sampling,transmission and processing of the RGB color signal in the LED video screen are described, and drive modes of the LED pixel are proposed, making use of TVGA8900 display adapter as an example. Finally, some practical problems in color correcting and flickering are discussed.
