    Abstract: A display device includes a display panel, an input sensor disposed on the display panel and including a plurality of first sensing electrodes and a plurality of second sensing electrodes, and a sensor controller configured to control the input sensor. The sensor controller receives a first signal from the input sensor and transmits a second signal to the input sensor. The first signal received from the input sensor includes down-link signals from first sensing electrodes corresponding to a first input position and a second input position among the plurality of first sensing electrodes and down-link signals from second sensing electrodes corresponding to the first input position and the second input position among the plurality of second sensing electrodes. The first input position corresponding to a first input source, and the second input position corresponding to a second input source, are spaced apart from each other.

    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.
