Numerical simulation on a novel cell structure: Chevron HAN-FFS mode LCD cell structure by TechWiz LCD
In this paper, a novel cell structure, named as chevron hybrid alignment nematic by fringing field switching (HAN-FFS), is proposed for realizing higher transmittance and wide-viewing angle. The proposed structure comprises a modified pixel electrode with grooves at an angle of 45 degrees in upper part and -45 degrees in lower part of the one cell. Moreover, it has vertical surface in the middle of the cell. Transmittance of the chevron HAN-FFS had about 1.2 times than that of wedge-shaped HAN-FFS. And the saturation time is shorter for the chevron HAN-FFS than for the wedge-shaped HAN-FFS.
