Abstract
A display panel of a display device includes a pixel, a gamma voltage generator, and a driver. The gamma voltage generator generates gammas voltages. The driver converts a grayscale value of image data into a voltage value, using a gamma lookup table corresponding to an input luminance value, and provides the display panel a data voltage corresponding to a gamma voltage among the gamma voltages, where the data voltage corresponds to the voltage value. The driver selects a first gamma lookup table and a second gamma lookup table from among predetermined gamma lookup tables corresponding to representative luminance values, based on the input luminance value, calculates a third gamma lookup table for the input luminance value by linearly interpolating the first gamma lookup table and the second gamma lookup table, and generates the gamma lookup table based on the third gamma lookup table.
