Electronic device comprising display and operation method thereof

An electronic device includes a display including a plurality of pixels; a display driver configured to provide a data voltage to the plurality of pixels of the display; and a processor configured to: obtain frequency change-based event information, determine a first frequency and a second frequency higher than the first frequency based on the frequency change-based event information, the first frequency being a target value of a refresh frequency, and provide frame data to the display driver, wherein the processor is further configured to control the display driver to: set a frame section in which the display is driven, during a first frame, generate the data voltage based on the frame data and provide the data voltage to the plurality of pixels, and during a low-frequency driving section, in which the frame data is not obtained, after the first frame, refresh an image based on the second frequency and refresh the image based on the first frequency.
