彩色显示器的通道独立性分析

彩色显示器在色彩管理中的转换模型都是建立在RGB三刺激值的可加性原理之上的，但是在实际应用中由于RGB三个通道之间存在相互干扰，使得红绿蓝的颜色合成结果在一定程度上偏离了叠加原理，实验表明，红绿蓝三个通道之间的干扰主要表现为一种相互抑制作用，而且造成的彩色显示器色彩转换模型的色差随显示亮度的增加而加大。因此，在色彩管理的模型转换中必须考虑这一误差，在平时的使用中一定要尽量避免让显示器工作在太亮的区域。

Analysis of Color CRT channels independence

All the transformation models of color CRT in the color management are based on the superposition principle of triune values. There exists a kind of "suppressive effect" among RGB channels in the practical CRTs, and this effect will invalidate the superposition principle. The experimental results show that the errors of the model caused by "interaction effect" will increase with the luminance values on the CRT screen. Therefore, the errors must be considered in the transformation and the light area should be avoided when using the CRT.
