Abstract
A gamma voltage generator included in a display device includes a gamma reference voltage storage block configured to store gamma reference voltage values at reference gray levels, an additional offset storage block configured to store additional offset values for the gamma reference voltage values at the reference gray levels, an additional offset setting block configured to store gamma select information representing whether the additional offset values are to be applied or not, a gamma reference voltage calculation block configured to generate final gamma reference voltage values by selectively adding the additional offset values to the gamma reference voltage values depending on the gamma select information, and a gamma reference voltage generation block configured to generate gamma reference voltages corresponding to the final gamma reference voltage values.
