1. A mutual capacitance touch panel device, comprising:
- 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, the drive electrode drivable independently of the pair of dual function electrodes,wherein within the array of electrode elements the drive electrodes are arranged orthogonal relative to the dual-function electrodes, andwherein 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 immediately 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.

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.
