Patent ID: 8507800

Claim:
A patterned substrate for use in a capacitive touch screen sensor assembly, the patterned substrate comprising; a substrate; a first non-metallic conductive layer disposed on the substrate, the first non-metallic conductive layer forming a pattern of electrodes; and a second non-metallic conductive layer disposed on the substrate, the second non-metallic conductive layer forming a pattern of traces that are each electrically coupled to at least one of the electrodes; wherein the second non-metallic conductive layer has a surface resistivity that is less than that of the first non-metallic conductive layer, and wherein the second non-metallic conductive layer has a surface resistivity of less than 20 ohms; and a flexible printed circuit (FPC) including an FPC substrate and a plurality of traces on a surface of the FPC substrate that are electrically coupled to the traces of the substrate formed by the second non-metallic conductive layer.
