Abstract
Disclosed is a display device including a display panel including a pixel, a scan driver, and a driving controller that controls driving of the scan driver. The scan driver provides the pixel with a first mode scan signal having a first active period and a second active period in a first mode and provides the pixel with a second mode scan signal having a compensation active period in a second mode. The driving controller determines whether an operating frequency of the display device corresponds to one of predetermined compensation frequencies in a variable frequency mode, and operates the scan driver in the first mode or the second mode depending on a determination result of the determining.
