针对电润湿显示器在播放视频时功耗较大的问题，设计了一套基于人眼视觉特性的低功耗视频显示驱动系统。该系统采用直方图修正与直方图匹配的方法，结合人眼视觉特性设定阈值，减少显示图像中高亮像素的数量从而降低系统功耗；同时提出一种低功耗多灰度驱动波形，结合电润湿显示器的光电特性，在实现灰度精准调制的同时进一步降低系统的功耗。实验结果表明：该系统改善了油墨分裂、油墨回流等问题，成功驱动了1 024×768分辨率的电润湿显示器且视频显示效果良好，像素的最高灰度等级达到16阶，在测量同一段视频时，平均功率降低至1.75 W，功耗减少约20%.

Aiming at the problem of high power consumption of electrowetting display during playing video, a low-power video display driving system based on human visual characteristics was designed. Adopting histogram correction and histogram matching, the system seta threshold value in combination with human visual characteristics to reduce the number of high-brightness pixels in the image, thereby reducing system power consumption. At the same time, a low-power multi-grayscales driving waveform was proposed, which combines the photoelectric characteristics of the electrowetting display to further reduce the power consumption of the system while achieving accurate gray-scale modulation. The experimental results show that the system improves the problems of oil-splitting and oil reflow, drives the 1 024×768 resolution electrowetting display successfully and the display effect is good. Besides, the highest gray level of the pixel reaches 16.When measuring the same video, the average power is reduced to 1.75 W and the power consumption is reduced by about 20%.
