Abstract
An electronic device and a method capable of reducing an afterimage of a display are provided. The method includes the operations of where a display panel is divided into a first area and a second area, in response to a specified event, controlling a display panel in a partial display state in which a first area is deactivated and a second area is activated, while the display panel is in the partial display state, dividing each frame into a first sub-period and a second sub-period, and controlling first pixels corresponding to the first area, controlling the first pixels to receive a data voltage corresponding to an inactive state, by supplying the first gate signal to the first pixels in the first sub-period, and controlling the first pixels to receive a bias voltage, by supplying the first gate signal to the first pixels in the second sub-period.
