摘　　要：彩色滤色膜是彩色液晶显示器的关键部件，为了提高彩色滤色膜的工作性能，研究了它的色度学问题。根据色度学的基本理论，采用Ｃ语言编写了计算程序，根据彩色滤色膜的透射光谱数据计算了三基色的ＣＩＥ（国际照明委员会）色度坐标以及饱和度和色差。对视角及标准光源对色度坐标的影响进行了讨论，并分析了影响光透过率及饱和度的几个因素，发现改变颜料的浓度或滤色膜厚度不能同时提高彩色滤色膜的光透过率和饱和度，而减小颜料的粒径是能够同时提高彩色滤色膜的光透过率和饱和度的有效方法。Color filter is a key component in liquid crystal display device. In order to improve its performance, some chromatic problems in color filter fabrication were studied. A calculation procedure was programmed using C language according to chromatic theory. On the basis of transmittance spectra data, the CIE (Commission International de I'Eclairage) chroma coordinates, the color difference and saturation of color filter were calculated. The effects of view angle and standard illuminators on calculation results were discussed. The influences of the pigment concentration, the film thickness and the pigment particle size on the transmittance and saturation of color filter were analyzed, and it was found that increasing the pigment concentration or the film thickness would improve the color saturation but lower the transmittance, and reducing the pigment particle size was a very useful method to improve the transmittance as well as color saturation of color filter. The color difference data under heat condition show the color filter has good heat resistance.
