碩士 === 國立臺北科技大學 === 光電工程系研究所 === 105 === The purpose of this thesis is to improve the electro-optical properties of a conventional two-domain (2D) fringe field switching (FFS) mode with the chevron electrode structure. We simulate the electrode structure and analyze electro-optical properties by the commercially available software, LCD Master 3D. The study is based on the 2D FFS mode with the chevron electrode structure. First, we simulate the conventional 2D-chevron FFS mode whose oblique angle of the patterned electrodes (θ) with respect to the polarizer transmittance axis is usually around 10º and analyze electro-optical properties. In this study, we proposed the method which reduces the oblique angle of pixel electrode until 2º in an FFS with 2D-chevron electrode. As compared to the conventional 2D-chevron FFS cell, the proposed FFS cell not only decreases the operating voltage, but also shows the higher light transmittance, wider luminance viewing angle, and lower color shift.
