Abstract: A touch sensor panel includes a first set of touch electrodes configured to operate as drive lines and that are disposed in a first layer of the touch sensor panel. The touch sensor panel also includes a second set of touch electrodes configured to operate as sense lines and that are disposed in a second layer of the touch sensor panel, different than the first layer of the touch sensor panel, such that one or more mutual capacitance touch nodes are formed by the first set of touch electrodes and the second set of touch electrodes. The touch sensor panel also includes a third set of touch electrodes configured to operate as self-capacitance electrodes and that are disposed in the first layer or the second layer of the touch sensor panel.

Abstract: A finger biometric sensor may include first and second integrated circuit (IC) dies arranged in a stacked relation. The first IC die may include a first semiconductor substrate and an array of finger biometric sensing pixels thereon, and the second IC die may include a second semiconductor substrate and processing circuitry thereon coupled to the array of finger biometric sensing pixels. The first and second IC dies may each have respective first and second non-rectangular shapes, such as circular shapes that are coextensive.
