摘　　要：反射式显示,又被称为电子纸显示,无背光源,利用环境光阅读,拥有类似“传统纸张”的观阅体验,有望成为主流显示技术之一。电泳显示技术(Electrophoretic display,EPD)作为一种新型的反射式显示技术,因其低成本、低重量、低功耗和高可靠性而备受关注。EPD基于带电粒子在介质流体中向相反带电电极的迁移而起作用,电泳粒子的一些参数如粒径大小、粒径尺寸分布和表面电荷等,对图像质量、图画控制和图像的响应速度有重要影响。因此,人们对电泳颗粒的制备、表面形貌修饰、微胶囊的制备等进行了大量研究,本文对这些方面的进展进行了综述。Reflective display which is also called electronic paper display without backlight,using ambient light to read and having a similar“traditional paper”viewing experience,may become one of the mainstream display technologies.Electrophoretic display(EPD),as a new reflective display technology,has attracted much attention because of its low cost,low weight,low power consumption and high reliability.EPD is based on the movement of charged particles through oppositely charged electrodes in dielectric fluid.Some parameters of electrophoretic particles,such as particle size,particle size distribution and surface charge etc.,have an important impact on image quality,image control and image response time.Therefore,the researchers have done a lot of work on the preparation,surface morphology modification of electrophoretic particles and preparation of microcapsules.This paper will review the progress in these fields of EPD.
