小范围内精确控制显示器亮度和色度方法研究

The method of precise control luminance and chrominance of display within a small range

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 luminance and chrominance of CRT display, the stability char- acteristics and ehroma deviation after relative stability of display are researched. Combined with the brightness and color characteristics of the display, a method to precisely control luminance and chrominance of the CRT display is put forward, and the experiments are carried out to verify it. The experimental results show that, the relative error controlled the brightness do not exceed 0. 8%. In the errors controlled color, the average chromatic aberration, the maximum chromatic aberration, the minimum chromatic aberration are respectively 0. 2358, 0. 5532, 0. 0287AE＊ ab. Results show that proposed method to control luminance and chromaticity of display can achieve to precisely control luminance and chrominance of the display better, which has more high control precision than the existing method of LUT and GOG model.
