Abstract

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.

基于一维查表的液晶显示器表征

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。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
