Method of RGBW compensation based on color aberrations of white subpixels and apparatus thereof

摘要

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 W_s of white subpixel and a standard white color coordinate point W_d under sRGB, analyzing color coordinates of every subpixel on the RGBW panel, and then dividing a triangle with vertices points R_s, G_s and B_s into three triangle regions based on W_s as the center point; based on ranges of the three triangle regions, a triangle region where W_d is located is confirmed; a first data is calibrated by performing compensating the white subpixel corresponding by the center point W_s via a predetermined normalized proportion through two subpixels corresponding to the other two points within the triangle region surrounding and locating W_d. Through the aforementioned manner, the present invention is capable of calibrating aberrations of white subpixels in order to normalize images of RGBW panels.
