Claim Text:
1. An organic light-emitting display device, comprising: an organic light-emitting display panel to display an image that includes a plurality of frames; a data driver to provide a plurality of data signals, which correspond to the image, to the organic light-emitting display panel; and a gamma voltage generator to provide a gamma voltage, which varies in a same period as each of the frames, to the data driver, wherein the organic light-emitting display panel includes a plurality of pixels to receive a power supply voltage, wherein the gamma voltage generator is to vary the gamma voltage as the power supply voltage received by the pixels varies, and wherein the gamma voltage generator is to reduce the gamma voltage to maintain a substantially constant potential difference between the power supply voltage received by the pixels and data voltages to be supplied to the pixels.
