RGBW子像素排列结构改进与色域映射优化算法

Improvement of RGBW Sub-Pixel Arrangement and Color Gamut Mapping Optimization Algorithm

针对现有的以RGBW为主的多基色图像显示,着重分析了RGBW子像素排列结构的工艺制造问题,以及常见的RGBW排列结构显示成像时的诸多缺点,并在此基础上提出一种新型的RGBWRGB子像素排列结构。在色域映射算法方面,指出常见的RGB到RGBW的色域映射算法在面对复杂图像时的缺点,并尝试在现有算法上进行改进以适配提出的新型子像素排列结构,从而实现转换后图像色彩的还原和亮度的提升。

Aiming at the current RGBW-based multi-primary display, we analyze the manufacturing problems of RGBW sub-pixel arrangement and the shortcomings of common RGBW permutation on displaying images, and present a new RGBWRGB sub-pixel arrangement structure. We also analyze the shortcomings of common gamut mapping algorithms with RGB to RGBW in the face of complex images, and try to improve the algorithms to fit the proposed sub-pixel arrangement, while maintaining the color saturation of the displayed image and lifting the brightness.
