碩士 === 中原大學 === 應用物理研究所 === 98 === Abstract In this thesis, we design single-mode single-cell-gap transflective LCDs by using floating electrode structure in the reflective area. The pixel electrode is extended from transmissive area to below the floating electrode of the reflective area. The induced voltage of the floating electrode is related to the applied voltage of the pixel electrode. Adjusting the overlap area of the pixel electrode and floating electrode, we can produce suitable voltages in the reflective area which make its V-T curve almost the same as that of the transmissive area. Two designs, Hybrid mode and vertically aligned mode, are propsed for the single-mode single-cell-gap transflective LCDs. The trajectories of the light traveling in the LC layers are illustrated in the Poincaré sphere. By using the compensation films, the viewing angle and the contrast ratio are improved. The electro-optic characteristics are confirmed by the simulation of TechWiz LCD 3D.
