Study on Pre-Polymer Effect in Polymer-Liquid Crystal System for Display Applications

Abstract

We reported the detecting method the remained pre-polymers during phase separation process. As phase separation of the LC and pre-polymers and polymerizations of the prepolymers with UV exposure are going by, the capacitance (or dielectric constant) values are changed and saturated. The saturating conditions (UV exposure conditions) could be detected by measuring the capacitance values during the UV exposure, simultaneously. That results are well matched to other characteristics of the cell such as VHR, RDC, and so on.
