Design of electronic shelf label based on electronic paper display

The Electronic Shelf Label (ESL) is an electronic display device based on LCD or electronic paper. In this work, we focus on the application of electronic paper display in ESL. We Put forward a kind of driver interface circuit from the electronic shelf label architecture and principle of electronic paper display controller and driver chip; Combined with electronic paper waveforms and SDRAM, we catch the design points of the driver and process; The scheme has been proved to achieve the image display and update with a good reading experience as traditional paper, so it has certain reference significance for electronic shelf label design, and will be beneficial to the popularity of electronic paper application and promotion.
