Claim:
1. A capacitive touch panel, comprising: a substrate; a multi-layer transparent conductive coating supported by the substrate, wherein the multi-layer transparent conductive coating comprises at least one conductive layer comprising silver located between at least a first dielectric layer and a second dielectric layer, wherein the multi-layer transparent conductive coating, comprising at least the conductive layer comprising silver located between at least the first dielectric layer and the second dielectric layer is patterned into a plurality of electrodes for the touch panel; a processor which measures capacitance between electrodes in detecting touch position on the touch panel, wherein the electrodes formed from the multi-layer transparent conductive coating are formed substantially in a common plane substantially parallel to the substrate, and wherein there is no more than a 2.0 difference at 600 nm between (a) a glass side visible reflectance percentage of the multi-layer transparent conductive coating on the substrate in areas where the coating is present, and (b) a visible reflectance percentage of the substrate in at least some areas where the multi-layer transparent conductive coating is not present.
