Abstract

In this paper, the method to increase the display intensity while preserving the hue and saturation of the input color is proposed in RGB+White 4-channel display devices. For this approach, the color gamut of the RGBW display is analyzed. The input color vector, incremental vector for increasing intensity, and a value for the white channel are analyzed and processed together in the color vector space. By this analysis, the proper correction vector for increasing the intensity and preserving the saturation can be obtained easily. The image test for this algorithm gives a good result for the brightness and saturation so that one can find out brighter image with vivid color without color clipping.
