针对RGB到RGBW显示系统的色域转换算法, 通过对当前显示领域已公开的两种色域转换方案进行研究、推导和Matlab实现, 分析了这两种方案的优缺点和适用范围, 并提出了一种色域转换算法的改进方案, 该方法能较好地改善由于加入了白色分量而导致色彩失真的问题。

Focusing on the color gamut conversion algorithm of RGB to RGBW display system, two kinds of schemes , which have been publicly reported, were studied and derived,and realized by the Matlab software,.The advantages, disadvantages and scope of the two kinds of schemes are analyzed. Meanwhile, an improved method of color gamut conversion algorithm, which can improve the color distortion situation caused by adding a white component, was put forward.
