基于RK2818的电泳电子纸驱动系统设计
The Design of Electrophoretic Electronic Paper Driving System Based on RK2818

为了提高电泳电子纸系统驱动性能和显示质量，文中提出了一种基于RK2818的电泳电子纸显示系统. 首先，利用RK2818平板处理器进行系统硬件设计，实现系统的图形图像处理能力；然后，围绕图片刷新过程，结合Pango和Cairo第三方开源库，对文本显示和图片显示效果进行研究，改善图片显示质量；最后，在Linux操作系统上实现了阅读器与浏览器的核心功能. 结果表明：电泳电子纸驱动系统实现了较好的图像显示效果，提高了电子纸阅读器的阅读体验.
： In order to improve the refresh rate and display quality of the electrophoretic electronic paper display (EPD), an EPD driving system based on RK2818 is proposed. Firstly, RK2818 flat panel processor is used for system hardware design to achieve graphics and image processing capabilities; secondly, the third-party open-source library such as Pango and Cairo are exploited for text and picture display to improve the picture display quality in the picture refresh process; lastly, a text reader and a file browser are realized in the Linux operating system. Experimental results show that a multi-functional EPD driving system with better image display is realized, which improves the reading experience of the EPDs
