摘　　要：本文在分析时分灰度法的基础上,提出一种子帧周期相等,并且位权重于电压参数的灰度调制方法,这种方法可以大幅度降低高分辨率LCOS器件的像素时钟频率,并消除时分灰度调制方法中潜在的闪烁现象。文中根据n位图像数据的比特位数值,把每帧分割成n个子帧,像素的灰度将由按照二进制位权重配置的驱动电压参数调制。Based on analyzing grayscale method of time-division, a scaling method, in which either frame is binary weighted by the voltage-parameter or the duration of sub-frames are equal, has been proposed for helping lower frequency of the pixel-clock and removing the flicker appearing with method of time-division. In this paper, each frame has been divided into n-sub-frames corresponding to the n-bit image data. The grayscale of pixel is controlled by the binary weight of the level of driving voltage.
