彩色双粒子微胶囊电泳显示的研究进展

Research Progress of color particles microcapsulated electrophoretic display

电子纸综合了传统纸张和新时代电子器件的优点,既如纸张一样阅读舒适、可弯曲折叠,又可以如液晶显示器一样不断转换刷新显示内容。微胶囊电泳显示使粒子的扩散和聚集禁锢在有限的空间范围内,改善了电泳液稳定性问题,延长了使用寿命,被认为是最具有发展前景的显示技术。本文在介绍各种电泳显示技术的基础上,着重介绍了微胶囊电泳显示技术。介绍了电泳白色无机粒子的表面改性,其次是电泳彩色有机粒子的表面改性,然后是电子墨水的制备方法以及微胶囊电泳显示的国内外商品化发展现状。

Electronic paper combines the advantages of conventional paper and electronic devices of the new era,it can be read comfortably as paper and be fold flexibly,as well as it can refresh contents as liquid crystal displays.Microcapsule electrophoretic display make the diffusion and aggregation of particle imprison within the limited space,that can improve the stability of electrophoretic fluid,prolong service life.It is considered to be one of the most developmental display technology.This article mainly introduces microcapsulated electrophoretic display technology,on the basis of the various electrophoretic display technology.Firstly,we introduce surface modification of the white electrophoretic inorganic particles.Secondly,the surface modification of color electrophoretic organic particles are discussed.In addition,we introduce the preparation of electronic ink and the development present situation at home and abroad of microcapsulated electrophoretic display.
