摘要
从色光加色混合的基本特性出发,对两台专业级液晶显示器(LCD)进行了光谱辐亮度测量。对测量结果进行计算表明,显示色与三原色光谱辐亮度函数之间存在线性叠加关系,不同数字驱动值下相同波长的三原色光谱辐亮度函数满足三次多项式的关系。利用这两个关系提出了一种根据数字驱动值和对应的三原色光谱辐亮度函数计算任意显示色的算法。实验验证结果表明,这种计算方法的准确度很高,可以作为LCD颜色特征化的方法。
For the color characterization of liquid crystal display （LCD）, the spectral radiance curves are measured for EIZO CG 19 and NEC PA241 LCD monitors and the displayed colors are calculated based on spectral additive property. The results show that the spectral radiance curve of displayed color is the linear superposition of those of corresponding primaries, and there is a cubic polynomial relation between the digital driving value and the corresponding radiance of a single wavelength. A new color computation method is proposed. The computation accuracy of the proposed method is very high. It can be used for the color characterization of LCD.
