48.5: Roll‐to‐Roll Manufacturing Process for Full Color Electrophoretic Film

Abstract

Abstract We report the process development work on roll‐to‐roll fabrication of EPD film that enables the making of full color EPD display. Through the incorporation of inkjet printing process, Microcup® web can be printed with colored fluids to form designated color pattern at sub pixel level. Existing roll‐to‐roll Microcup® EPD manufacturing process can be modified to accommodate the printing step and the processes can be coordinated in such to prevent the mixing of different colored fluids during web processing.
