摘　　要：目前大多数全彩ＬＥＤ显示屏中的灰度控制还是简单的线性灰度，由于人的视觉的明亮度与物理亮度的非线性关系，这种灰度处理方法存在着严重的灰度畸变．给出了一种基于反γ校正的ＬＥＤ显示屏灰度控制技术，实验结果表明可以显著改善视频播放效果．Nowadays ,the gray controls in most full color LED display screens are still linear contrik. This kind of gray control methods leads to decrease gray series owing to the nonlinear relation between the brightness of htunan’s sight feeling and physical brightness. A gray control technology for fun color LED display screens based on anti-γcorrection is described in this paper. Experiment results show the method improves the video playback effects.
