Original Abstract Submitted
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.
