Abstract
A display device including: pixels coupled to first scan lines, second scan lines, emission control lines, and data lines; a first scan driver configured to supply a first scan signal to each of the first scan lines at a first frequency; a second scan driver configured to supply a second scan signal to each of the second scan lines at a second frequency corresponding to a driving frequency of the pixels; an emission driver configured to supply an emission control signal to each of the emission control lines at the first frequency; a data driver configured to supply a data signal to each of the data lines at the second frequency; and a timing controller configured to control the first scan driver, the second scan driver, the emission driver, and the data driver.
