Abstract: An electronic device includes a display panel and an image sensor. The image sensor is disposed under the display panel to spatially correspond to a location of a partial area on the display panel. In response to a request occurring while the display panel is not driven or is in a stand-by mode, the display panel emits light having brightness equal to or higher than a reference brightness through pixels spatially corresponding to a location at which the image sensor is disposed. The image sensor outputs an image signal associated with an object on the partial area, based on the emitted light.
