摘要

基于LCD(Liquid Crystal display)的彩色显示原理，比较了现有的两种表征方法。由于LCD的色彩空间与器件相关，因此对LCD进行了表征。将LCD(RGB)的色彩空间映射到CIE标准色彩空间(CIE XYZ)。采用CIELAB色差公式对数据进行评价。分析了两种表征方法(一维查找表(1D-LUT)和增益-偏移-伽马模型(GOG))的适用性。结果表明，两种表征方法的测试值和预测值的平均色差分别为1.56、8.87，证明1D-LUT的准确率高于GOG模型的准确率。而且，1D-LUT的色彩再现能力优于GOG模型。

Characterization of LCD based on 1-dimension look-up table

Based on the color display principle of LCD(Liquid Crystal Display),two existing methods of characterization are compared.Since the color space of LCD is device-dependent,the characterization of LCD is carried on.The color space of LCD(RGB)to the CIE standard color space(CIE XYZ)is mapped.The data are evaluated by the color difference formula of CIELAB.The applicability of two methods(1-Dimention Look-Up Table(1D-LUT)and GOG(Gain-Offset-Gamma)Model)of characterization are analyzed.Results show that the average color difference of the tested value and the predicted value of the two characterization methods are respectively 1.56,8.87,which prove that the accuracy of 1D-LUT is higher than the accuracy of GOG Model.What’s more,the ability of color reproduction of 1D-LUT is better than the GOG Model.
