| dc.description.abstract | 本論文以邊緣電場(Fringe-field)為主要的驅動方式，產生FFS液晶模態，使得液晶顯示器具備基本的廣視角及良好的光電效率。首先根據wide-band原理，設計出具有wide-band效果的混合配向反射式結構，討論參數對光電曲線的影響。接著依照相同的觀念，設計兩種穿透式結構：水平配向與混合配向的穿透式結構。
利用模擬軟體2DIMMOS，根據反射式結構的特性，微調反射或穿透區的相關參數，改善E-O curve不一致的問題。接著再利用模擬軟體TechWiz LCD，藉由理論計算結果，外加正C plate，補償相位遲滯片與液晶層。最後我們可設計出同時具有TR match與廣視角的半穿透半反射液晶顯示器。 | zh_TW |
| dc.description.abstract | In this thesis, we use fringe-field as the major drived method to producing FFS LC mode. This kind of LCD has wide viewing angle and good electro-optic efficiency. At first, according to wide-band theory, we can design the hybrid aligned reflective LCD which have wide-band effect. Then, we discuss the influences of parameters on E-O curve. Secondly, we design two different transmissive structures in the light of the same concept : parallel aligned and hybrid aligned transmissive structures.
By using the 2DIMMOS software, we fine tune the related parameters of reflective or transmissive region in order to improve the inconsistence of E-O curve. According to the result of calculation with theory, we add positive C plates to compensate the retarder and LC layer by the software TechWiz LCD. After a series of simulations and corrections, we can finally devise a transflective LCD which is TR matched and with wide-viewing angle property. | en |
