摘要

为了解决电润湿电子纸显示器存在的视频闪烁、电荷泄露问题以及实现电润湿多灰度动态显示，本文针对电润湿电子纸显示器研究设计了一套驱动系统。首先，根据完整的电润湿电子纸驱动系统必须具备的功能，提出了嵌入式+现场可编程门阵列（FPGA）的驱动系统架构，其中嵌入式平台可以对视频源进行实时图像处理，FPGA根据接收到的处理后的数据进行相应的时序控制。接着，采用现有电泳电子纸的源栅驱动芯片作为电润湿电子纸的驱动芯片。最后，本文提出了不等子帧和复位帧的概念用以解决视频闪烁和电荷泄露问题从而更好地实现多灰度显示。实验结果表明：该驱动系统成功解决了电润湿视频闪烁、电荷泄露以及多灰度显示等问题，使电润湿电子纸的视频刷新率达到30 Hz，像素最高灰度可以达到16灰阶并且在该灰度下的电润湿反射率接近60%。整个驱动系统基本满足了多灰度动态显示。

Abstract

In order to solve the problems of video scintillation

charge leakage and achieving dynamic multi-grayscale display on electrowetting electronic paper displays

a set of driving system was designed for the study of electrowetting electronic paper displays. First of all

this paper proposes a driving system architecture of embedded platform + FPGA based on the functions that the complete electrowetting electronic paper drive system must have

in which the embedded platform can carry out real-time image processing on the video source.And the corresponding timing control will be achieved by FPGA according to the received processed data. Next

the source gate driver chip of the existing electrophoresis electronic paper is used as the driver chip of the electrowetting electronic paper. Finally

this paper proposes the concepts of unequal subframes and reset frames to solve the problem of video flicker and charge leakage so as to achieve a better multi gray scale display.The experimental results show that the drive system successfully solves the problems of electrowetting video flicker

charge leakage and multi-grayscale display problems.The video refresh rate of the electrowetting electronic paper reaches to 30 Hz

the maximum gray level of the pixel can reach 16 gray scale and the reflectivity is close to 60% at the highest gray level.The whole drive system basically meets the dynamic display of multi grayscale.
