Abstract
A display device includes a display panel comprising a plurality of pixels, a data driver configured to generate data voltages based on a gamma reference voltage, and to provide the data voltages to the plurality of pixels, a gate driver configured to provide gate signals to the plurality of pixels, and a controller configured to control the data driver and the gate driver. The controller is configured to initialize the gamma reference voltage when a blank period starts in a frame period comprising an active period and the blank period, and to change the gamma reference voltage when a duration of the blank period reaches at least one threshold time.
