摘要

由于液晶显示器上的原色偏移不可忽略，常用的原色不变性模型不能很好地应用于液晶显示器上。为了使lcd的平均色差小于3/spl Delta/E/sub uv/*，需要对主不变正演模型进行至少3/spl times/9的回归分析矩阵修正。在反向模型中，多项式回归方法可以同时传输RGB和XYZ域的数据。然而，只有在XYZ域中，所需的颜色才能充分再现。

Color reproduction of twist nematic LCD by polynomial regression applied in primary-invariance model

As primary-shifts on LCDs is non-negligible, primary-invariance model, widely used to characterize the color reproduction on CRT monitors, can not be applied well on LCDs. To obtain average color difference of less than 3 /spl Delta/E/sub uv/* for LCDs, primary-invariance forward model should be modified by at least a 3/spl times/9 regression analysis matrix. In backward model, polynomial regression method can transfer data in both RGB and XYZ domains. However, only in XYZ domain, desired colors can be reproduced sufficiently.
