Abstract
Provided is a display device including a display panel including a plurality of pixels, a data driver which provides a data voltage to each of the plurality of pixels, a scan driver which provides a scan signal to each of the plurality of pixels, a sweep driver which provides a sweep signal to each of the plurality of pixels, and a controller. Each pixel includes a light emitting element, a pulse width modulation circuit which receives the data voltage in response to the scan signal, and generates a pulse width modulation signal based on the data voltage and the sweep signal, and a current generation circuit which provides a current to the light emitting element based on the pulse width modulation signal. A slope of the sweep signal is changed in a plurality of modes having different maximum luminances.
