Abstract
The present invention discloses a method of RGBW compensation based on color aberrations of white subpixel and an apparatus thereof: when aberrations exist between a color coordinate point Wof white subpixel and a standard white color coordinate point Wunder sRGB, analyzing color coordinates of every subpixel on the RGBW panel, and then dividing a triangle with vertices points R, Gand Binto three triangle regions based on Was the center point; based on ranges of the three triangle regions, a triangle region where Wis located is confirmed; a first data is calibrated by performing compensating the white subpixel corresponding by the center point Wvia a predetermined normalized proportion through two subpixels corresponding to the other two points within the triangle region surrounding and locating W. Through the aforementioned manner, the present invention is capable of calibrating aberrations of white subpixels in order to normalize images of RGBW panels.
