Abstract: A display device can include a display panel including a plurality of pixels configured to be driven in one of a driving period and a blank period, a timing controller configured to output a variable refresh rate (VRR) signal determining a refresh rate of the plurality of pixels and a video data signal, and a data driver configured to supply a data voltage to the plurality of pixels through a plurality of data lines, according to the VRR signal and the video data signal. The plurality of pixels can be driven at a first refresh rate or a second refresh rate which is lower than the first refresh rate, according to the VRR signal. Further, when the plurality of pixels are driven at the second refresh rate and the video data signal is a low grayscale video data signal, the output luminance of each of the plurality of pixels can be reduced during the blank period.
