Abstract

A method includes storing a set of touch sense values corresponding to a measured characteristic of at least one unit cell of a plurality of unit cells of the touch array and accessing a correction matrix that defines an active region and an inactive region of the touch array. The inactive region is surrounded by the active region. The method further includes modifying touch sense values of a first subset of the plurality of unit cells that are partially within the active region defined by correction values of the correction matrix.
