Abstract: An apparatus for generating gamma voltage includes a plurality of gamma set generators and a gamma set selector. The gamma set generators generate a plurality of gamma voltage sets that include gamma voltages having different voltage levels from each other such that each gamma voltage set corresponds with a brightness mode. The gamma set selector selects any one of the gamma voltage sets in response to the brightness mode and drives data lines of a display device in accordance with the selected gamma voltage set.
