Abstract:
The display device includes a display panel in which a first display area and a second display area adjacent to the first display area are defined, a data driving circuit which drives the plurality of data lines, a scan driving circuit which drives the plurality of scan lines, and a driving controller which receives an image signal and a control signal, and controls the data driving circuit and the scan driving circuit based on an operation mode, where the driving controller includes a luminance deviation compensation unit which compensates for luminance deviation of the first display area and the second display area when the operation mode is a multi-frequency mode in which the first display area is driven at a first frequency and the second display area is driven at a second frequency different from the first frequency.
