Abstract
An electronic device is provided. The electronic device includes a memory, a display driver integrated circuit (DDIC), a display, and a processor that generates an image frame, transmits the image frame to the DDIC, and controls the DDIC to drive the display based on the image frame. The DDIC outputs a first timing signal at a first frame period, outputs a second timing signal at a second frame period longer than the first frame period when the reception of the image frame is delayed, and outputs a third timing signal at a third frame period longer than the first frame period and shorter than the second frame period when the image frame is not received for a designated reference time after the second timing signal is output.
