P-57: Wide Viewing Angle of Double-Domain STN-LCDs

摘要

A double-domain STN-LCD (DDSTN-LCD) was studied. The DDSTN cell has two kinds of alignment states, they have same twisted angle, but their directors of liquid crystal molecule are different and perpendicularly each other on each of pixel. The DDSTN LCD showed excellent viewing angle characteristic. In this paper, we also analyzed the decrease of contrast of DDSTN LCD and discussed the method to solve this problem.
