Abstract: A display device may include a display panel including a plurality of pixels. An interpolator may be configured to generate a first voltage value corresponding to an input data value using a preset gamma lookup table. A gamma compensator may be configured to, based on a dimming value, select at least one of a plurality of preset dimming lookup tables, and may calculate a first output data value by correcting the first voltage value based on the at least one dimming lookup table. A gamma voltage generator may be configured to generate a plurality of gamma voltages having a linear relationship. A data driver may be configured to select a first gamma voltage from among the gamma voltages based on the first output data value, and provide the first gamma voltage, as a data voltage, to the display panel.
