We have developed a color and flexible electronic paper display using electronic liquid powder. Novel types of color display either colored powder or color filter are discussed. We have also developed a flexible display with low cost substrate films with a high throughput roll‐to‐roll manufacturing system. These technologies enable QR‐LPD® to be used widely as an electronic paper display.

Abstract— Color displays and flexible displays that use electronic liquid powder have been developed. Novel types of color displays using either a colored powder or a color filter are discussed. We have also developed a flexible display with low‐cost substrate films with a high‐throughput roll‐to‐roll manufacturing method. These technologies enable a QR‐LPD to be widely used as an electronic‐paper display.
