An electronic device includes a display panel including at least one light source, a point detector disposed on one surface of the display panel or inside the display panel, and at least one processor operatively connected with the display panel and the point detector. The at least one processor is configured to cause the at least one light source to emit light in response to an object outside the display panel, detect, through the point detector, at least a portion of the emitted light reflected by at least a portion of the object, and obtain biometric information corresponding to the object based on the detection.
