Abstract: An electronic device includes a display panel including a base layer, and an element layer disposed on the base layer, the element layer including pixels outputting a first light, and light receiving sensors, an input device providing a second light to the display panel, and a control module controlling operations of the display panel and the input device. The light receiving sensors detect the second light provided from the input device and generate a detection signal. The control module calculates biometric information of a user based on the detection signal.
