The Design of Electrophoretic Electronic Paper Driving System Based on RK2818

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.
