摘　　要：电润湿是指通过改变作用于液体-固体电极间的电势,来影响固体和液体间的界面张力,从而改变固液界面的润湿性,即接触角,使液滴产生形变、位移的现象.电润湿电子纸显示是基于快速响应微流体操控技术的新型反射式“类纸”显示技术.该技术拥有已商业化的电泳电子纸显示产品低能耗、视觉健康、可柔性等优点,同时突破了“彩色”和“视频播放”两项当前束缚电子纸显示技术应用领域的瓶颈.未来,电润湿电子纸显示将为我国军用、民用市场提供全天候“绿色”显示产品,具有千亿规模的直接市场和巨大产业辐射力.本文对电润湿显示器件中涉及的多个物理方向,特别是润湿与电润湿、两相流体力学、微观与界面物理、光物理、电介质物理、热物理、瞬态物理等,进行了系统综述;并且对基本器件工作原理、微观与介观物理图像、器件运行内在机制、器件可靠性等进行了全面介绍.Electrowetting refers to the phenomenon of modifying the surface tension between a liquid and a solid by adjusting the externally applied electric potential between the liquid and solid electrodes,thereby changing the contact angle between the two and causing a deformation and displacement of the droplets.Electrowetting electronic paper display is a new reflective“paper-like”display technology based on a rapid response microfluidic control technology.It has the advantages of low energy consumption,visual health,and flexibility of commercial electrophoretic electronic paper display products,while breaking through the bottlenecks of“fullcolor”and“video-speed response”that currently restrict the application of electronic paper display technology.In this paper,several physical directions involved in electrowetting display devices,especially wetting and electrowetting,binary phase fluid mechanics,microscopic and interfacial physics,photophysics,dielectric physics,thermophysics,and transient physics,are systematically reviewed;the basic principles of device operation,microscopic and mesoscopic physical pictures,internal mechanisms of device operation,and device reliability are also discussed in detail.
