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

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.
