摘要：An optical compensation method for an organic light emitting display devicecomprises: setting initial gain values of RGB subpixels; making each of the RGB subpixels
converge on target luminance; selecting subpixels to emit light with the W subpixel fromthe RGB subpixels, and setting an initial gain value of the W subpixel; measuring colorcoordinates and luminance of the W subpixel to which the initial gain value is applied;calculating the luminance ratio of the W subpixel and the selected subpixels; adjustingmaximum gains of the W subpixel and the selected subpixels; measuring maximum colorcoordinates and luminance ratio of the W subpixel and the selected subpixels; andmaking the W subpixel and the selected subpixels converge on target color coordinatesand luminance.
