Abstract: An electronic device includes a display panel that operates in a normal mode, a multi-frequency mode, or a refresh mode, a driving controller, and a host generating and outputting a luminance information. In the multi-frequency mode, a display area defined in the display panel is divided into a first display area and a second display area, and the driving controller controls the first display area and the second display area so as to operate at different frequencies. In the normal mode, the driving controller controls the display area so as to operate at a normal frequency. In the refresh mode, the driving controller controls the display area so as to operate at the normal frequency during one frame. When the luminance information changes, the display panel operates in the refresh mode.
