1. An optical compensation method for an organic light emitting display device, the method comprising:
setting initial gain values of red (R), green (G), and blue (B) subpixels; making each of the R, G and B subpixels converge on a target luminance for each subpixel; wherein the making each of the R, G, and B subpixels converge on the target luminance comprises:
measuring color coordinates of each of the R, B, and B subpixels to which the initial gain values are applied;calculating a luminance ratio of the R, G, and B subpixels; andadjusting maximum gains of the R, G, and B subpixels; selecting subpixels to emit light with a white (W) subpixel from the R, G and B subpixels, and setting an initial gain value of the W subpixel; measuring color coordinates and a luminance of the W subpixel to which the initial gain value is applied; calculating a luminance ratio of the W subpixel and the selected subpixels; adjusting maximum gains of the W subpixel and the selected subpixels; measuring maximum color coordinates and a maximum luminance ratio of the W subpixel and the selected subpixels; and making the W subpixel and the selected subpixels converge on target color coordinates and luminance. |
