Abstract
A gamma voltage generator, method of generating gamma voltage, and an OLED display including the generator are disclosed. In one aspect, the generator includes a gamma reference voltage selector configured to receive a gamma reference voltage from a voltage generator and output selected first to third gamma voltages having values substantially equal to or less than the gamma reference voltage. The generator also includes a medium gamma voltage selector configured to receive the first to third gamma voltages from the gamma reference voltage selector and select and output a plurality of medium gamma voltages based at least in part on the first to third gamma voltages. The generator further includes a medium gamma voltage calculator configured to output a selection signal corresponding to the calculated low gamma voltage to the medium gamma voltage selector.
