Abstract
Electronic Paper Display(EPD) can exhibit good comfortability in reading,but it has a critical drawback slow refresh,which will be overcome by optimizing the design of the display's driver software.A tri-buffer-based architecture as well as its design methodology for the EPD driver software was proposed in this paper.Also an e-reader integrating the EPD driver in it was implemented to verify the design.Compared with the traditional dual-buffer architecture,the proposed tribuffer scheme allocated an additional memory area to keep the EPD data frame.Test results show that the driver software works well on a real device without screen flicker and can help the display to achieve excellent performance.
