Abstract:
A display device includes pixels coupled to first scan lines, second scan lines, emission control lines, and data lines; a first scan driver to supply a scan signal to each of the first scan lines at a first frequency to drive the display device at a first driving frequency, and to supply the scan signal to each of the first scan lines at a second frequency to drive the display device at a second driving frequency lower than the first driving frequency; a second scan driver to supply a scan signal to each of the second scan lines at the first frequency to drive the display device at the first driving frequency, and to supply the scan signal to each of the second scan lines at the second frequency to drive the display device at the second driving frequency; an emission driver to supply an emission control signal to each of the emission control lines at the first frequency; and a data driver to supply a data signal to each of the data lines in response to the scan signal supplied to each of the first scan lines.
