Abstract
A display device includes a plurality of pixels connected to scan lines and data lines, a data driving circuit that outputs data signals to the pixels via the data lines, a scan driving circuit that sequentially activates at least some pixels via the scan lines, and a driving controller that controls both circuits. The display panel includes a first display area with first pixels and a second display area with second pixels. The scan driving circuit activates both display areas at a first scan rate in a first operation mode and activates the second display area at a second scan rate in a second operation mode, where the second scan rate is lower than the first scan rate.
