Abstract Electrowetting display technology is realized by tuning the surface energy of a hydrophobic surface by applying a voltage based on electrowetting mechanism. Electrowetting displays have favorable optical properties combined with reflective paper‐like performance. It has been successfully demonstrated in reflective mode with high switching speed. In this paper, we propose a portable driving scheme that can display 4‐bit gray scale dynamic video using an active matrix electrowetting display. The proposed driving scheme includes an electronic system and a dynamic driving waveform design. High‐performance multi‐gray video playing and quick response were obtained for a Quarter Video Graphics Array electrowetting display cell fabricated by our team.
