1. An electronic device, comprising:
a display panel;
a display driver integrated circuit (DDIC) configured to drive the display panel; and
a processor, wherein the processor is configured to:
control the DDIC to drive the display panel in a split screen state based on a user input, wherein the split screen state comprises a state in which an entire display area of the display panel is divided into a plurality of areas and in which the plurality of areas are driven independently each other,
execute a first application,
execute a second application,
execute a third application,
determine a first driving frequency configured by the first application and a position of a first part on which a first execution screen of the first application is to be displayed,
determine a second driving frequency configured by the second application and a position of a second part on which a second execution screen of the second application is to be displayed,
determine a third driving frequency configured by the third application and a position of a third part on which a third execution screen of the third application is to be displayed,
determine whether the first part and the second part are disposed adjacent to each other in a direction perpendicular to a scan direction of the display panel,
calculate a least common multiple of the first driving frequency and the second driving frequency in response to the first part and the second part being disposed adjacent to each other in a direction perpendicular to a scan direction of the display panel,
control the DDIC to drive a first area of the display panel including the first part and the second part of the display panel based on a first partial refresh rate corresponding to the least common multiple, and
control the DDIC to drive a second area of the display panel including the third part of the display panel based on a second partial refresh rate corresponding to the third driving frequency.
