    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.

    Abstract: A foldable electronic device includes: a display panel including a pixel array, a first region, a second region, and a folding region interposed between the first region and the second region, a plurality of gate lines connected with respective gates of a plurality of transistors included in the pixel array and extending in a first direction, a plurality of data lines connected with respective sources of the plurality of transistors and extending in a second direction crossing the first direction, a gate driving circuit connected with the plurality of gate lines, a display driver integrated circuit (DDI) connected with the plurality of data lines, a first detection line connecting a first gate line of the plurality of gate lines corresponding to the folding region with the DDI, a processor, and a memory operatively connected with the processor. The foldable electronic device is configured to be folded as the folding region is bent such that the first region corresponds to the second region, the DDI is configured to detect a first gate driving voltage applied to the first gate line by the gate driving circuit using the first detection line, and to transmit, to the processor, defect information indicating that the folding region is defective based on the first gate driving voltage being less than a reference voltage, and the memory stores instructions which when executed, cause the processor to: receive the defect information from the DDI, identify at least a portion of the folding region and/or the second region, based on the defect information as a defective region, and control the display panel to display an execution screen on the first region based on the identified defective region.
