Fingerprint Sensor with Proximity Detection, and Corresponding Devices, Systems, and Methods

摘要

An electronic device includes a housing and a user interface. One or more processors are operable with the user interface. The user interface includes a touch sensor that includes a fingerprint sensor and at least one proximity sensor component. The proximity sensor component can be collocated with a thermally conductive band circumscribing the fingerprint sensor, or can be concentrically located with the fingerprint sensor. The proximity sensor component can actuate the fingerprint sensor upon receiving an infrared emission from an object external to the housing. The fingerprint sensor or proximity sensor component can then be optionally used to control the electronic device.
