摘　　要：通过对TFT液晶屏的彩色滤色器光谱透过率曲线和不同背光源的光谱分布分析,研究彩色滤色器及背光与TFT液晶显示器的色彩的相互关系,提出了通过设计背光光谱改善液晶显示器色域的技术方案。结果表明：设计合适的背光光谱与液晶屏彩色滤正膜匹配,可以将色域提高10%~50%。The relationship of color filter and backlight with the color of TFT LCD was studied according to the analyse of color filter spectrum transimssion curve of TFT LCD and different backlight.Then a project depending on designing backlight spectrum to increase the LCD color gamut was proposed.It turns out that the LCD color gamut would increase 10 to 50percent by matching the spectrum at backlight with color filter.
