Patent ID: 7800597

Claim:
A display device, comprising: a display panel configured to display images corresponding to a first data voltage and a second data voltage for a frame, the frame having a first sub frame and a second sub frame; and a driver configured to provide the display panel with the first data voltage corresponding to frame data inputted from an external device according to a first gamma curve during the first sub frame and configured to provide the display panel with the second data voltage corresponding to the frame data according to a second gamma curve during the second sub frame, wherein a gamma value of the second gamma curve is greater than a gamma value of the first gamma curve and the driver includes: a gamma storing unit configured to store a first reference gray scale data corresponding to the first gamma curve and a second reference gray scale data corresponding to the second gamma curve; a reference gray scale voltage generation unit configured to generate a first reference gray scale voltage and a second reference gray scale voltage based on the first and second reference gray scale data, respectively; and a data driver configured to convert the frame data into the first and second data voltages based on the first and second reference gray scale voltages, respectively, and configured to provide the first and second data voltages to the display panel.
