    Abstract: On an electronic device which includes a display device comprising a display driving circuit, a processor, and a memory a method for changing a refresh rate of the display device includes: changing at least one of a first parameter, a second parameter, or a third parameter in response to identifying the occurrence of at least one of a scan rate change request or a change in scan rate change restriction, and applying the changed parameter among the first parameter, the second parameter, and the third parameter. The first parameter is the frequency of a first synchronization signal generated in the display driving circuit, the second parameter is the increase or decrease in a blank area to substitute for a portion of active video area in frame information, and the third parameter is the frequency of a second synchronization signal for rendering.

    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 according to one embodiment of the present invention can comprise a display panel, a display controller, a memory, and a processor electrically connected to the display panel, the display controller, and the memory. The memory can store instructions, when executed, which allow the process to: draw an image in response to a periodic synchronization signal; compose the drawl image in response to the synchronization signal after the drawing of the image; transmit the composed image to the display controller in response to synchronization signal after the composing of the image; measure, after the transmitting of the composed image, a first standby time until the next synchronization signal is generated; perform control such that the display panel displays an image in response to the generation of the next synchronization signal; determine a first offset value on the basis of the first standby time; and determine an image composition time point by applying the first offset value to the periodic synchronization Additionally, various examples are possible.
