摘　　要：针对现有快刷电子纸产品在多帧刷屏后容易出现残影显示问题,从电子纸纸膜(FPL)、电子纸背板TFT设计、电子纸波形(WF)设计的角度进行深入分析产生残影现象原因,提出优化电子纸驱动系统最佳Vcom电压及优化快刷波形驱动算法的解决方案,并介绍了优化快刷波形驱动算法方案中减少刷屏次数算法和插入清屏波形算法两种方法。经实验验证,快刷显示的残影现象得到明显改善。In view of the existing issue of sticking-image easily appears after the fast e-Paper display refreshed multiple times.To further investigate the reason of sticking-image,the core components of e-Paper including front plane lamination(FPL)film,thin film transistor(TFT)and waveform(WF)are critically analyzed.Thus,new solutions that optimizing the best common voltage and driving waveform algorithms are proposed to resolve the sticking-image phenomenon.Meanwhile,two methods of optimizing driving waveform algorithms,reducing refresh times and inserting clear waveform,are introduced in detail.Finally,the experimental results demonstrate that the sticking-image phenomenon is significant improved.
