Abstract: An electronic device includes a housing, a display carried by the housing, and a fingerprint sensor also carried by the housing. The electronic device may also include a processor for generating a plurality of menu items on the display, and for scrolling an indicator along the menu items based upon static placement of a finger adjacent a selected portion of the fingerprint sensor. The sensor may have a polygonal shape, and the scrolling may be in a direction of a corner portion of the polygonal shape. The menu items may be arranged in a single column, or in a plurality of columns.

Abstract: A fingerprint sensor may include a plurality of electrostatic discharge (ESD) electrodes carried by a dielectric layer of a fingerprint sensing portion. The fingerprint sensing portion is for sensing a fingerprint of a user. The fingerprint sensing portion may include the dielectric layer, and, in some embodiments, may also include an array of sensing electrodes also carried by the dielectric layer. Accordingly, each ESD electrode may be interposed between adjacent sensing electrodes. The ESD electrodes attract ESD events and dissipate the energy therein to avoid damaging adjacent sensing electrodes and/or portions of the dielectric layer. The fingerprint sensor may also include an electrically conductive layer connected to the ESD electrodes, which may provide a convenient ground plane, for example, for removing ESD energy from the fingerprint sensor. The electrically conductive layer may extend beneath the sensing electrodes.
