Disclosed is a method of RGBW compensation based on color aberrations of white subpixel and an apparatus thereof: when aberrations exist between a color coordinate point Ws of white subpixel and a standard white color coordinate point Wd under sRGB, analyzing color coordinates of every subpixel on the RGBW panel, and then dividing a triangle with vertices points Rs, Gs and Bs into three triangle regions based on Ws as the center point; based on ranges of the three triangle regions, a triangle region where Wd is located is confirmed; a first data is calibrated by performing compensating the white subpixel corresponding by the center point Ws via a predetermined normalized proportion through two subpixels corresponding to the other two points within the triangle region surrounding and locating Wd. Through the aforementioned manner, the present invention is capable of calibrating aberrations of white subpixels in order to normalize images of RGBW panels.
