Abstract: A display device which includes a display panel that includes a first display area and a second display area, and a driving controller. During a multi-frequency mode, the driving controller drives the first display area by using a first driving frequency and drives the second display area by using a second driving frequency. During the multi-frequency mode, when the second driving frequency changes from a first frequency to a second frequency, the driving controller drives the first display area and the second display area during at least one frame by using a base frequency, drives the first display area and the second display area during at least one second frame by using an intermediate frequency between the base frequency and the second frequency, and then drives the first display area by using the first driving frequency and drives the second display area by using the second frequency.

Abstract: An electronic device includes a display panel, a first timing controller, and a second timing controller. The first timing controller generates a first error flag signal, the second timing controller generates a second error flag signal, and the first timing controller and the second timing controller exchange the first error flag signal and the second error flag signal with each other. The first timing controller controls a first completion signal, and the second timing controller controls a second completion signal. When the first completion signal is activated and the second completion signal is activated, the first timing controller and the second timing controller drive the first display region and the second display region of the display panel.
