Abstract:
In a method of compensating gamma reference voltages includes setting a plurality of emission signal on-duty ratios that have different values in a range from 0% to 100%, setting a plurality of data offsets for the emission signal on-duty ratios and each of the data offsets being set based on a color shift, the color shift being caused according to the emission signal on-duty ratios, generating a plurality of compensation gamma reference voltages by multiplying a gamma reference voltage by the data offsets, and applying the compensation gamma reference voltages to an organic light emitting display panel in dimming ranges that include the emission signal on-duty ratios, respectively.
