摘要： An electronic device is provided. The electronic device includes a display panel and a display driver integrated circuit configured to drive the display panel. The display driver integrated circuit is configured to determine a luminance value of the display panel if a request for a change from a current driving frequency of the display panel to a target driving frequency is received, and determine at least one intermediate driving frequency between the current driving frequency and the target driving frequency depending on the luminance value of the display panel.

摘要： 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 drawn 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 mage, 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 signal. Additionally, various examples are possible.
