Abstract: A display device include: a display panel including first to third pixels, a data driver for providing first to third data voltages to the first to third pixels, and a scan driver for providing first and second scan signals to each of the first to third pixels. The scan driver performs a first active scan operation of sequentially providing the first and second scan signals to the first to third pixels in a first frame period, and perform a dummy scan operation of sequentially providing the second scan signal to the first to third pixels after the first active scan operation. The data driver changes a voltage level of at least one of the first to third data voltages in an overlap period in which the dummy scan operation and a second active scan operation of a second frame period are simultaneously performed.

Abstract: A display device includes: a display panel, and a driving controller to receive an image signal and a control signal, drive the first display region of the display panel at a first driving frequency, and drive the second display region at a second driving frequency. The driving controller counts a first stress time of each of the first horizontal lines, and calculates a first operating time of each of the first horizontal lines based on the first stress time and the first driving frequency, counts a second stress time of each of the second horizontal lines and calculates a second operating time of each of the second horizontal lines based on the second stress time and the second driving frequency, and outputs an image data signal obtained by compensating for stress for the image signal based on the image signal, the first operating time, and the second operating time.
