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

位图像数据的比特位数值，把每帧分割成

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。

Abstract

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

-sub-frames corresponding to the

-bit image data. The grayscale of pixel is controlled by the binary weight of the level of driving voltage.
