1. An electronic device comprising:
a display panel which operates in a normal mode, a multi-frequency mode, or a refresh mode, and in which a display area is defined;
a driving controller which controls the display panel; and
a host which generates a luminance information including a luminance value of the display area and outputs the luminance information to the driving controller,
wherein, in the multi-frequency mode, the display area is divided into a first display area and a second display area immediately next to the first display area, and the first display area and the second display area operate at different frequencies by the driving controller,
wherein, in the normal mode, the display area operates at a normal frequency by the driving controller,
wherein, in the refresh mode, the display area operates at the normal frequency during one frame by the driving controller, and
wherein, when the luminance information changes, the display panel operates in the refresh mode.
