US Patent 11398107 Fingerprint-touch combined sensor and electronic device including the same

A sensor for recognizing a fingerprint and sensing a touch is provided. The sensor includes a touch sensing area in which a first touch electrode and a second touch electrode are arranged to provide touch sensing nodes at which touch sensing is performed; and a fingerprint-touch sensing area comprising a fingerprint recognition area in which a first fingerprint electrode and a second fingerprint electrode are arranged and electrically separated from the first touch electrode and the second touch electrode, the first fingerprint electrode and the second fingerprint electrode being configured to provide fingerprint sensing nodes at which a fingerprint is recognized in a fingerprint recognition mode, wherein in the fingerprint recognition area, a portion of the first fingerprint electrode and the second fingerprint electrode is used for fingerprint recognition and, as the touch sensing nodes, the touch sensing.
