Display device

A display device comprising:

• a display panel including a red pixel, a green pixel, and a blue pixel;
• a data driver which provides a data voltage to each of the red pixel, the green pixel and the blue pixel;
• a scan driver which provides a scan signal to each of the red pixel, the green pixel and the blue pixel;
• and
• a sweep driver which provides a first sweep signal to the red pixel, provides a second sweep signal to the green pixel and provides a third sweep signal to the blue pixel,
• wherein each of the red pixel, the green pixel, and the blue 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 a corresponding one of the first, second, and third sweep signals;
• and
• a current generation circuit which provides a current to the light emitting element based on the pulse width modulation signal, and
• the first sweep signal, the second sweep signal, and the third sweep signal include different slopes.

An electronic device comprising:

• a processor configured to provide input image data;
