Abstract
A display device includes: a pixel unit including a plurality of pixels connected to a plurality of scan lines and a plurality of data lines; a multi-frequency driver configured to compare image data between adjacent frames to determine a first area of the pixel unit driven at a first refresh rate and a second area of the pixel unit driven at a second refresh rate lower than the first refresh rate; a scan driver configured to sequentially supply scan signals to the scan lines in a first direction, to supply first scan signals of the scan signals to the first area at the first refresh rate, and to supply second scan signals of the scan signals to the second area at the second refresh rate; and a data driver configured to supply a data signal corresponding to the image data to the data lines.
