提出了一种制备聚合物分散液晶（PDLC）显示器的剥离方法。聚合物基质模板可以通过从氟硅烷化防粘基材上剥离PDLC膜来预制。然后可以将期望的液晶回填/渗透到模板中。应用该技术制备的二向色PDLC的反射率为66%，对比度为13.8：1，在3.8英寸。四分之一视频图形阵列反射薄膜晶体管（TFT）显示器。采用含有三聚氰胺-甲醛纳米颗粒的漫射层来抑制由反射背板引起的金属眩光。该技术适用于各种背板，例如柔性、溶剂/UV敏感的有机TFT。(c)2006年，美国物理学会。
A lift-off method has been developed for the fabrication of polymer dispersed liquid crystal (PDLC) displays. A polymer matrix template can be prefabricated by lifting off a PDLC film from a fluorosilanized antisticking substrate. Desirable liquid crystal can then be backfilled/infiltrated into the template. Applying this technique to fabricate dichroic PDLC yielded a reflectivity of 66% and a contrast ratio of 13.8:1 in 3.8 in. quarter video graphics array reflective thin film transistor (TFT) displays. A diffuse layer with melamine-formaldehyde nanoparticles was employed to suppress the metallic glare caused by the reflective back plane. The technique is suitable for various back planes such as flexible, solvent/UV-sensitive, organic TFTs. (c) 2006 American Institute of Physics.
