3.4: Dual‐Mode Switching Electrophoretic Displays with Thermally Reversible Gelators

Abstract

Electrophoretic displays (EPDs) play an essential role in the Internet of Things (IoT) environment with the unique eye‐friendly feature and visibility for high‐ambient‐illumination. However, good bistability is in conflict with the fast response. Here, we introduced a gelator‐doped electronic ink to demonstrate the capability of operating the EPD with both static display mode and fast‐moving mode through temperature change. The high threshold voltage and ultra‐fast response time were achieved in the same EPD device. This method may provide a new direction for the future development of the electronic paper.
