Abstract
We have developed a process for fabricating flexible reflective display devices using thin composite films of aligned polymer-monostabilized ferroelectric liquid crystals encased between plastic substrates. In order to precisely control the thickness of these films, photolithography is used to fabricate spacer posts on a substrate, and a printing technique that can form a liquid crystal/monomer solution film on the substrate uniformly. Control voltages are applied to the layer via transparent electrodes; in order to prevent a short circuit between these electrodes, an insulator layer is also formed on the other substrate. Once the two substrates are attached to one another, polymer walls and fibers are created in the liquid crystal layer between the two substrates by photopolymerization-induced phase separation which was induced by two-step exposure of ultraviolet light. A fabricated device is sandwiched between a polarizer and a diffuse mirror to make a reflective display. Uniform display operation was obtained when the device was driven with a voltage, even when the device was bent with a 5-cm radius of curvature. © 2007 Wiley Periodicals, Inc.

一种利用铁电液晶和聚合物的复合薄膜制造柔性反射显示装置的方法
我们已经开发了一种制造柔性反射显示器件的工艺,该工艺使用排列在塑料衬底之间的聚合物单稳定铁电液晶的薄复合薄膜。为了精确控制这些薄膜的厚度,采用光刻技术在衬底上制造间隔柱,以及在衬底上均匀形成液晶/单体溶液薄膜的印刷技术。控制电压通过透明电极施加到层上;为了防止这些电极之间的短路,在另一个衬底上也形成绝缘体层。一旦两个衬底相互连接,通过两步紫外线照射诱导的光聚合诱导相分离,在两个衬底之间的液晶层中产生聚合物壁和纤维。在偏光镜和漫反射镜之间夹上一个制造出来的装置,就形成了一个反射显示器。当电压驱动器件时,即使器件弯曲半径为5cm,也能获得均匀的显示操作。©2007 Wiley期刊公司电子工程学报,2009,31 (2):393 - 393;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecjb.20192版权所有©2004 Wiley期刊公司
