Abstract: An electronic device and a method for driving a plurality of display areas of a display at different driving frequencies are provided. The electronic device can determine a first driving frequency of a first application, and the position of a first portion on which a first execution screen of the first application is to be displayed, determine a second driving frequency of a second application, and the position of a second portion on which a second execution screen of the second application is to be displayed, determine a third driving frequency of a third application, and the position of a third portion on which a third execution screen of the third application is to be displayed, and drive a first area of the display panel based on a first partial scan rate, and drive a second area of the display panel based on a second partial scan rate.
