新型电子纸显示技术用电泳粒子的设计与制备

Design and Preparation of Electrophoretic Particles Used for New Type Electronic Paper Display Technique

电泳显示技术的工作原理是基于分散在透明或彩色液体中的带电粒子在一定电场下的电泳作用,具体是在排列成像素结构的两片电极之间的移动行为而显示种种图像,其优点是:在日光下有良好的可读性、能耗少、生产潜在成本低、可制作成柔性的电子纸、应用范围广等,因此很有发展前景。电泳粒子是电子纸的基本组成,作者设计和研究制备成功与分散相密度匹配的黑色、白色和红、绿、兰等色的电泳粒子,为改善电子纸显示效果提供基础材料,本文扼要阐述此项研究。

The working mechanism of electrophoretic display technique is based on the electrophoresis of charged particles dispersed in a transparent or colored liquid moving in a specific electric field,i.e.their moving between two arrays of electrodes arranged to form pixels will display miscellaneous images.Its advantages includes： good readability under sun light,power saving,lower potential production cost,suitable for making flexible e-paper,wide application field etc,thus will have very promising development prospects.Elctrophoretic particles are the main constituent of electronic paper,the authors designed,researched and achieved successively to prepare black,white,and blue,green,red colored electrophoretic particles having specific mass matching very well the dispersion phase,consequently offering basic materials for improving the effects of electronic paper,this paper expatiated on this subject.
