Abstract
Electronic paper (E‐paper) relies on reflecting ambient light to achieve information display, which mimics the appearance of printed papers, but owns the features of conventional electronic displays. The outstanding characters of E‐paper including visual health, comfortable outdoor viewing and ultra‐low power consumption, attracts increasingly interests in display society. E‐paper technology has evolved slowly in the field of color reproduction and video frame rate, until the arise of electrowetting display (EWD) technology. Benefits from the innately high speed response of microfluidics, EWD enables the displaying of color video content. In this report, the basic physics of electrowetting displays, including electro‐optical response and color reproduction method will be discussed. In this presentation, recent progress on above topics, including printed conductive pillar directed oil motion control and parallax issue in CMY stacked EWD device will also be discussed.
