Abstract

The invention discloses a split-screen synchronous display method for electrophoresis electronic paper and electrowetting electronic paper. The method comprises the following steps: S1, receiving a video stream output by an external video source; s2, converting the video stream into a parallel RGB (Red, Green, Blue) data stream; s3, performing inter-frame difference calculation on the parallel RGB data stream to generate a frame difference data stream; s4, asynchronously caching the frame difference data stream to adapt to the difference between the output frame rate of the external video source and the refresh rate of the electronic paper display equipment; s5, based on the asynchronously cached frame difference data flow, respectively generating driving signals suitable for the electrophoresis electronic paper and the electrowetting electronic paper; and S6, respectively outputting the driving signals to the electrophoresis electronic paper display equipment and the electrowetting electronic paper display equipment so as to realize synchronous split-screen display. According to the invention, multiple problems in real-time dynamic display of the existing electronic paper are solved.
