Abstract

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 tri-buffer scheme set an additional memory area to keep the EPD data frame. Test results show that the driver software works well in a real device without screen flicker and can help the display to achieve excellent performance.

Key words: Electronic Paper Display (EPD), driver software, tri-buffer, e-reader

摘要：

电子纸显示器(EPD)能展现良好的阅读舒适性，但它具有显示速度慢的缺点，这必须通过对显示驱动程序进行优化设计加以克服。提出了一种基于三缓冲区的EPD驱动程序的实现架构和设计方法，并在一个专用阅读设备上进行了实现和验证。与传统的双缓冲机制相比，三缓冲架构增设了一个EPD显示区，用于保存显示到屏幕上的数据帧。测试结果表明，该驱动程序工作正常，不会出现屏幕闪烁问题，显示效果良好，用户可以获得较佳的视觉体验。
