Abstract

Optical bounce during switching in the fringe field switching (FFS) mode using a liquid crystal (LC) with positive dielectric anisotropy has been observed. According to the analysis, it occurs at two positions which are center and edge of the pixel electrode, which decreases decaying response time. The former is major and mainly associated with increase in twist angle instantaneously during switching off resulted from decrease in tilt angle near by LC molecules at center. This paper discusses the origin of such optical bounces.
