摘要

在负性液晶里加活性单体聚合物经过两次UV制程，制得IPS-RM LCD，通过AOI光学自动检测设备以及DMS光学测量等对获得样品的预倾角、对比度、穿透率进行了测量，并研究了负性液晶加RM后的信赖性。结果表明：加RM后预倾角变小，其暗态亮度降低，对比度提高；经过两次UV光照，RM完全聚合，在配向层表面形成小颗粒聚合物，使液晶配向更加均匀，并得到更强的锚定能，电压保持率提升，直流电压残余降低。

Abstract

An IPS-RM LCD was fabricated by adding RM(Reactive Mesogen) into negative LC and exposuring two times under UV processing. The pretilt angle

contrast ratio and transmittance were measured using AOI (Automated Optical Inspection) and DMS(Display Measuring System)

and the reliability of the sample with RM was researched. The results indicate that the pretilt angle became smaller after adding RM

and the luminance of the dark state decreased

thus the contrast enhanced. The RM polymerizes completely after two times UV irradiation to generate small granule polymer on the surface of alignment layer

which makes the LC aligned more homogeneous

and achieve stronger anchoring energy. The voltage holding ratio (VHR) increases and the residual direct current (RDC) decreases.
