【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。
[Abstract]:Based on the analysis of time division gray method, this paper presents a gray level modulation method with equal subframe period and a bit weight on voltage parameters. This method can greatly reduce the pixel clock frequency of high resolution LCOS devices. The potential scintillation phenomenon in time division gray level modulation method is eliminated. According to the bit values of n-bit image data, each frame is divided into n sub-frames, and the gray level of the pixel will be modulated by the driving voltage parameters configured according to the binary bit weight.
