Abstract

A method of increasing color gamut of a color display includes grouping subpixels of R, G, and B primary colors of a pixel by grouping R, G, and B light sources of the color display with a corresponding light intensity adjustment mechanism based on an overlapping degree between two response spectrums of the light sources. The response spectrums of the light intensity adjustment mechanism of the same group have minimal overlapping with that of other groups. The method further includes enabling groups of R, G, and B subpixels, activating the R, G, and B light sources and the corresponding light intensity adjustment mechanism, and disabling the remaining groups of subpixels all by turns for creating a vivid complete picture by time division color-mixing.
