Design and implementation of electrowetting multi-gray dynamic display driving system
摘要
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 de-signed for the study of electrowetting electronic paper displays.First of all,this paper proposes a driv-ing system architecture of embedded platform + FPGA based on the functions that the complete elec-trowetting 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 e-lectrophoresis 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 elec-tronic paper reaches to 30 Hz,the maximum gray level of the pixel can reach 16 gray scale and the re-flectivity is close to 60% at the highest gray level.The whole drive system basically meets the dynamic display of multi grayscale.关键词
