Abstract

A display device includes a luminance correction unit that corrects input data based on a dimming code value and outputs correction data, a gamma correction unit that corrects the correction data and generates output data, a gamma voltage generator that generates gamma voltages depending on a first voltage code value, a data driver that converts the output data into data voltages based on the gamma voltages, and a controller that supplies the dimming code value and the input data to the luminance correction unit and provides the first voltage code value to the gamma voltage generator. The controller compares a highest dimming compares a highest dimming grayscale value of the output data determined by the dimming code value with a highest reference grayscale value and updates the first voltage code value with a second voltage code value.
