Abstract: An electronic device includes a cover glass, a touch sensor disposed under the cover glass and sensing proximity of or contact by an external object, a touch integrated circuit (IC) electrically connected to the touch sensor, a fingerprint sensor disposed under the cover glass adjacent to the touch sensor, including an active area for sensing a biometric pattern of the external object and an inactive area surrounding a periphery of the active area, a fingerprint IC electrically connected to the fingerprint sensor, and a processor electrically connected to the touch IC and the fingerprint IC. The processor is configured, if an input by the external object is sensed by both the touch sensor and the fingerprint sensor, to calculate coordinates of the input based on at least part of data sensed by the touch sensor and data sensed by the fingerprint sensor.
