摘　　要：研究LED背光对液晶器件色彩的影响和CSTN及TFT-LCD白色色度坐标的变化规律,以及LCD的红、绿、蓝三色受LED背光的影响规律及色彩还原性的变化,并对背光发光光谱和液晶屏的透过光谱进行了测量比较。This article studied the effect of LED backlight on color performance of CSTN and TFT liquid crystal devices. The relation of white chromaticity coordinate of liquid crystal device and backlight chromaticity coordinate was studied. The influence of LED backlight on red, green and blue color of liquid crystal device and its color gamut was studied as well. The spectrum measurement was also done to understand different color performance of liquid crystal devices using the same panel and different LED backlights.
