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.

Abstract: A touch sensor panel can include a silver nanowire touch electrodes formed in a silver nanowire layer on the substrate. In some examples, the touch sensor panel can include one or more anticorrosion layers to protect silver nanowire layer from ionization. In some examples, the silver nanowires include electrochemically stable outer shells that protect the silver nanowires from ionization. Additionally or alternatively, the touch sensor panel can including one or more anti-static layers to protect against electrostatic discharge (ESD). Additionally or alternatively, one or more anticorrosion layers and/or one or more antistatic layers can be formed with a passivation layer therebetween. The passivation layer, one or more anticorrosion layers and/or one or more antistatic layers can then be laminated to the silver nanowire layer to prevent corrosion and/or ESD events in the silver nanowire layer during the fabrication of the touch sensor panel.
