LCD (Liquid Crystal Display) 產品領域體積小與低功率的優點為平面顯示器提供良好的利基。若能經由檢測規範取得量測數據並進行分析,則即能根據量測結果辨識LCD 顯示器的好壞。因為生產和製程參數的變化,生產線出廠的每片LCD表現出的色度座標都會稍有不同,面板廠都會以相同之色域值做為規範。本論文利用一組伽瑪曲線資料作為基礎進行調整校正,比較後可由數據及照片中得知有較好之色域表現。並探討LCD的顏色飽和度和閃爍對於LCD品質的影響。


LCD products have been making great strides they supply the media of flat panel displays with good niche in the future developments due to their small volume size and low power consumption. Measured results can not only distinguish between good and bad for LCD but also give a correction of the image quality.
LCD color coordinates from the production line of the LCD factory will vary from products to products. However LCD factories use the same color standard to evaluate their products. This thesis makes use of the measured gamma curve to correct gamma curve via programming for improving LCD flicker noise and color quality.
