Abstract

The display device includes a display panel including a plurality of pixels; a driver IC configured to convert digital data corresponding to an input image to an analog voltage using a gamma voltage, and to supply the analog voltage to the plurality of pixels; and a power supply configured to supply a pixel driving voltage to the display panel and the driver IC. The driver IC includes a weight selector configured to select a weight for adjusting the gamma voltage based on a change amount of the pixel driving voltage supplied from the power supply; and a gamma reference voltage generating unit configured to generate a gamma reference voltage based on the selected weight.
