Abstract: A display device includes pixels which are connected to first scan lines, second scan lines, third scan lines, emission control lines, and data lines; a scan driver which supplies a bias scan signal to each of the third scan lines at a first frequency and supplies a scan signal to each of the first scan line and the second scan line at a second frequency which corresponds to an image refresh rate of each of the pixels; an emission driver which supplies an emission control signal to each of the emission control lines at the first frequency; a data driver which supplies a data signal to each of the data lines at the second frequency; and a timing controller which controls driving of the scan driver, the emission driver, and the data driver.

Abstract: A display device includes: a pixel unit having a plurality of pixels; a timing controller supplying respective scan start signals to a plurality of scan drivers and an emission start signal to an emission driver, in response to synchronization signals supplied from the outside; the emission driver supplying an emission signal to emission control lines connected to the pixels based on the emission start signal; the scan drivers supplying scan signals to the scan lines connected to the pixels based on the scan start signal; and a data driver supplying a data signal to data lines connected to the pixels, and at least one of a frequency of the emission start signal and frequencies of the scan start signals may be a first frequency that is determined independently of a driving frequency when the driving frequency is less than or equal to a threshold value.
