Abstract
An apparatus may include a capacitive touch controller, a ball grid array package, firmware, and a driven shield driver circuitry. The ball grid array package may comprise a plurality of balls arranged in multiple concentric rings. The firmware may dynamically select a driven shield pattern based on a received aspect ratio input corresponding to a capacitive sensor array. The driven shield driver circuitry may activate the driven shield balls according to the dynamically selected driven shield pattern to electrically isolate drive balls from sense balls.
