Abstract

Electrofluidic displays were first reported in 2009, and transpose brilliantly colored pigment dispersions via competition between electromechanical and Young–Laplace pressure. To our knowledge, this is the first display technology to use a three-dimensional (3-D) microfluidic device structure and leverages brilliantly colored aqueous pigment dispersions. Reported herein is a brief review of electrofluidic display technology. The review includes the device operating principle, fabrication, speed, brightness, and color performance. Also presented is recent progress in key areas needed for realizing products, including bistability, fabrication on flexible substrates, and performance in various temperatures (varied from −28°C to 80°C).
