1. A multilayer interdigitated projected capacitance touch screen comprising:

  • a substantially transparent first layer comprising a dielectric film presenting a pair of opposing surfaces, wherein at least one of the opposing surfaces of the film is coated with a conductive material, the conductive material defining a plurality of electrically interconnected regions and a plurality of electrically isolated regions adjacent and interspersed with the electrically interconnected regions; and

    a substantially transparent second layer comprising a dielectric film presenting a pair of opposing surfaces, wherein at least one of the opposing surfaces of the film is coated with a conductive material, the conductive material defining a plurality of electrically interconnected regions and a plurality of electrically isolated regions adjacent and interspersed with the electrically interconnected regions, the second layer superimposed on the first layer such that each of the electrically interconnected regions of the first layer is overlain with an electrically isolated region of the second layer, and each of the electrically isolated regions of the first layer is overlain with an electrically interconnected region of the second layer.
