Abstract
Disclosed is a display device including a display panel. The device includes a reference voltage generator, a controller, and a data driver. The controller is configured to receive an input image signal and a dimming value, convert the dimming value into the dimming control signal, and convert the input image signal into image data. The reference voltage generator is configured to receive the dimming control signal and output a correction reference voltage by correcting at least one of a first gamma reference voltage and a second gamma reference voltage based on the dimming control signal. The data driver is configured to receive the correction reference voltage, generate gamma voltages based on the correction reference voltage, convert the image data into data voltages based on the gamma voltages, and output the data voltages to a display panel with pixels.
