Abstract: An example electronic device includes a display panel configured to display a screen, a display driver IC (DDI) configured to supply a data voltage for displaying the screen to the display panel, and a processor configured to transmit image data for setting the data voltage to the DDI. The DDI is configured to generate a synchronization signal for controlling a time point at which the data voltage is supplied to the display panel, and to deliver the synchronization signal to the processor. The processor is configured to select a time point, at which the image data starts to be transmitted, within a waiting period of the synchronization signal.

Abstract: According to an embodiment, an electronic device may include at least one processor, a display, a memory configured to store image frames, and a display controller configured to output the image frames. The at least one processor may be configured to transmit a first image frame to be output through the display, based on a first timing signal received from the display controller, identify a state of the electronic device, transmit first control information for changing a timing of the first timing signal, in response to transmitting the first control information for changing the timing of the first timing signal, receive a second timing signal from the display controller, and transmit, to the memory, a second image frame to be output through the display, based on the received second timing signal. The timing of the second timing signal may differ from the timing of the first timing signal.

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.
