Study On The Influence Of Rubbing On The Multi-Domain Chlcd

The technology of rubbing is one of important methods to form the multi-domain structure in the reflective cholesteric liquid crystal display. We have studied the influence of the pile impression, the rotation frequency and the roller transport velocity on the phase transition voltage of the CHLCD respectively. The results of the experiments showed that a gentle pile impression with a small rotation frequency and a fast roller transport velocity can achieve a low phase transition voltage of the multi-domain CHLCD.
