碩士 === 國立臺灣大學 === 光電工程學研究所 === 94 === This thesis studies the methods, which make transflective LCDs electro-optical characters match equally. This thesis uses four topics to deal with the different electro-optical curve. The following is the topics：（1）The method of changing liquid crystal parameters、（2）Top-Bottom TFT electrode LCD（I）、（3）Top-Bottom TFT electrode LCD（II）、and （4）Patterned Common(P.C.) electrode TR LCD design. Those studies base on FFS mode（Fringe-Field Switching） which has high light efficiency、fast response time、and wide viewing angle property. To go a step further, the four topics match transmissive LCDs and reflective LCDs E-O curve. In （1）The method of changing liquid crystal parameters, different pretilt angle is the major method for matching threshold voltage（Vth）which could get more matched E-O curve of T & R part. In （2）Top-Bottom TFT electrode LCD（I）、（3）Top-Bottom TFT electrode LCD（II） and （4）Patterned Common(P.C.) electrode TR LCD design, the three topics take new structure design to get the same transflective LCDs E-O curve. This study is helpful for improving electro-optical characters of transflective LCDs and may be useful to the applications of small size flat-planel display.
