Abstract:
A method of gamma correction for an organic light emitting display device includes calculating a high-power voltage to be supplied in an emission period of the organic light emitting display device based on a gray-level range of an input image data for each frame, generating a gamma correction curve for the calculated high-power voltage based on a predetermined minimum gamma correction curve and a predetermined maximum gamma correction curve, performing a gamma correction on image data based on the gamma correction curve to generate gamma-corrected image data, and displaying the gamma-corrected image data on the organic light emitting display device.
