More Information
Summary:An electronic paper display device and an operation method thereof are provided. The electronic paper display device includes an electronic paper display panel and a timing controller. The timing controller includes a first image buffer memory, a second image buffer memory, and an update buffer memory. The timing controller receives a touch track data. The first image buffer memory and the second image buffer memory are a ping-pong buffer architecture, and receive a video stream in staggered timing. The second image buffer memory receives the touch track data and simultaneously updates a current display screen data stored in the update buffer memory when the first image buffer memory receives the video stream to update the current display screen data into the update buffer memory. The timing controller drives the electronic paper display panel according to the current display screen data.
