Maximization of Electro-Optic performances in the Fringe-Field switching liquid crystal mode using a liquid crystal with negative dielectric anisotropy

The fringe-field switching (FFS) mode that uses liquid crystals (LC) with negative dielectric anisotropy is used in high resolution FFS-LCD owing to its higher transmittance over positive LC. In this paper, the FFS mode with electrode width 1 jum and distances between the electrodes 1.5 fim is proposed. In such an electrode structure, operating voltage (Vop) decreases with decreasing eel! gap to 2 ftm so that a proper V0p, high LCs light efficiency of 90%, and a fast response time less than 10 ms, can be achieved, which maximizes electro-optic performance of the FFS mode. In addition, the color temperature of a white state becomes higher in the fine patterned FFS cell.
