通过对CRT显示器的亮度和色度的实验测量,研究了显示器的稳定特性和其相对稳定后的色度偏差。结合显示器的亮度和显色特征,提出了一种精确控制CRT显示器的亮度和色度方法,并通过实验进行了验证。实验结果表明,亮度控制相对误差不会超过0.8%。在色度控制误差中,其平均色差、最大色差、最小色差分别为0.2358、0.5532、0.0287ΔE*ab。结果表明,提出的显示器亮度和色度控制方法能够较好的实现精确控制显示器的亮度和色度,比现有的LUT和GOG模型方法具有更高的控制精度。
Through the experimental measurement of brightness and chromaticity of CRT display, the stability characteristics of the display and the chromatic deviation of its relative stability have been studied. Combined with the brightness and color rendering characteristics of a display, a method of precisely controlling the brightness and chromaticity of a CRT display is proposed and verified through experiments. The experimental results show that the relative error of brightness control will not exceed 0.8%. In the chromaticity control error, the average color difference, the maximum color difference and the minimum color difference are 0.2358, 0.5532 and 0.0287ΔE * ab, respectively. The results show that the proposed display brightness and colorimetric control method can achieve better control of the brightness and chromaticity of the display, and has higher control precision than the existing LUT and GOG model methods.
