P-168L:Late-News Poster: 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 µm and distances between the electrodes 1.5 µm is proposed. In such an electrode structure, operating voltage (Vop) decreases with decreasing cell gap to 2 µm so that a proper Vop, high LC's 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.
