A patterned substrate for a touch screen sensor assembly that includes a plurality of electrodes that are formed from a first transparent conductive layer that has a first surface resistivity. The substrate also has a plurality of traces that may be used to couple the electrodes controller associated with the touch screen sensor assembly. The traces are formed from a second conductive layer that has a second surface resistivity that is less than the surface resistivity of the first conductive layer. The first and second conductive layers may be formed from indium tin oxide (ITO) having different surface resistivities. A second, similarly configured substrate can be provided and may be spaced apart from the first substrate by a dielectric spacer.

Capacitive touch panel having dual resistive layer

A method for manufacturing a touch screen sensor assembly that includes providing a first transparent substrate, depositing a first non-metallic conductive layer onto the first substrate, removing the first conductive layer from a viewing portion of the first substrate, depositing a second non-metallic conductive layer onto the viewing portion, and removing portions of the second and first conductive layers to respectively form a first electrode pattern and a plurality of traces. The disclosed method also includes providing a second transparent substrate, depositing a third non-metallic conductive layer onto a viewing portion of the second substrate, removing portions of the third conductive layer to form a second electrode pattern, and bonding the first substrate to the second substrate using an optically clear adhesive. Each trace on the first substrate formed from the first conductive layer is electrically coupled to at least one electrode of either the first or second electrode patterns.
