| 摘 要： | ＬＥＤ显示屏存在显示刷新速度不够、灰度层次不足等缺点，为此，根据其特殊结构，对数字视频信号的数据进行重构，采取特殊的位平面存贮方式和扫描技术，以达到稳定的高速动画显示效果。文章详细讨论了其组成原理及实现方法。实践表明：采用这种位平面技术制成的ＬＥＤ全彩屏，灰度层次好，图象稳定不闪烁，电路实现简单而灵活。

| Abstract: | Low display updating speed and less gray scale grades exist in LED display. For this, data restructure of digital video signal is made according to its special structure, and special bit plane encoding memory and scanning technology are used to achieve stable and high speed display effect of animation. This paper details the configuring principle and its realization. The practice proves:all color LED display with bit plane encoding technology results in good gray scale with stable image without flutter, and the circuit is easy and flexible. |
