Abstract:
A touch sensor panel is disclosed. The touch sensor panel can include a first substrate layer; a first electrode layer comprising one or more of a touch electrode and a trace configured to couple the touch electrode to sense circuitry, the first electrode layer located on a first side of the first substrate layer; a second electrode layer located on the first side of the first substrate layer; a passivation layer disposed in between the first electrode layer and the second electrode layer; and a third electrode layer located on a second side of the first substrate layer, different from the first side of the first substrate layer. The first electrode layer can be comprised of a first conductive material, the second electrode layer can be comprised of a second conductive material, and the third electrode layer can be comprised of a third conductive material. The touch sensor panel may not include a second substrate layer between the first substrate layer and the second electrode layer.
