1. A capacitive sense array, comprising:
a two-dimensional array of capacitive sense elements, each capacitive sense element formed by a respective intersection of (i) a respective row electrode in a first electrode layer and (ii) a respective column electrode in a second electrode layer, wherein:
each column of the capacitive sense elements comprises a respective n column electrodes that are interdigitated with each other and electrically disconnected from each other, n being a positive integer greater than 1, each of the respective n interdigitated electrically disconnected column electrodes intersecting each row electrode in the first electrode layer; and
each row electrode forms n rows of capacitive sense elements at intersections with the column electrodes.
