Abstract

A mutual capacitance touch panel device includes a substrate and an array of electrode elements formed on the substrate, each electrode element including a drive electrode and a pair of dual-function electrodes. In addition, the pair of dual-function electrodes of each electrode element are arranged substantially symmetrically around the drive electrode of the respective electrode element such that a first dual-function electrode of the pair is adjacent to the drive electrode and the second dual function electrode of the pair is separated from the drive electrode by the first dual-function electrode.
