Abstract
A gamma voltage setting method of a display device includes: supplying, to a data driver, data corresponding to a specific grayscale of a specific dimming level; generating a data signal corresponding to the data in the data driver, using a gamma voltage corresponding to a processing gamma value; displaying an image corresponding to the data signal in a pixel unit; determining a temperature of the pixel unit; loading, from a look-up table, a target luminance and a target color coordinate, which correspond to the specific dimming level, the specific grayscale, and the temperature of the pixel unit; generating a gamma value such that an image corresponding to the target luminance and the target color coordinate is displayed in the pixel unit; and storing the gamma value.
