摘要:	為了實現高品質的大型液晶電視，薄膜電晶體顯示器必須具備更優良的品質。因此，改善液晶顯示器的視角特性，消除色偏問題是實現高品質液晶電視的重要課題。目前有許多的廣視角技術用來解決液晶顯示器因視角改變而產生色偏的問題，但這些技術需要較高的技術或提昇成本來達成。本論文提出三種以顏色混色的方法搭配優化的運算來找出適當的混色比例，進行顏色的補償，減少因視角改變而產生色偏。第一種方法是以RGB三色進行加法混色補償。第二種方法是以RG、GB、BR進行混色補償。第三種方法是以R、G、B分別加入W進行混色補償。 It is emergent for TFT-LCD devices to improve their performance，especially in large scale LCD TV. It becomes more and more important that how to widen the viewable angle and how to reduce the color shift induced by different viewing angle. Although there are many kinds of technologies to solve these problems，those technologies currently still require very complicated process and are with great cost. In the thesis，a novel method based on color mixing with the optimal color compensation has been proposed to effectively reduce the color shift induced by different viewing angle. Three ways of color compensation are compared with each other：(1) color mixing with three color primitives (red，green，and blue)；(2) color mixing with two color primitives(red with green，green with blue，and blue with red)；and(3) color mixing with additional white color.
