Abstract: Certain example embodiments relate to capacitive touch panels. First and second glass substrates are substantially parallel and spaced apart from one another. At least one multi-layer transparent conductive coating (TCC) is patterned into electrodes and located between the first and second substrates. The TCC(s) include(s) at least one conductive layer including silver, a dielectric layer including zinc oxide under and directly contacting the conductive layer including silver, and a dielectric layer(s) including tin oxide or silicon nitride over the conductive layer including silver. Processing circuitry electrically connects to the electrodes and measures an aspect of the electrodes' capacitance. A laminate material is located between the first and second glass substrates. The TCC(s), when blanket deposited, may have a visible transmission of at least 88%, a sheet resistances of no more than 10 ohms per square, and a haze of no more than 0.5%. Mutual and self-capacitance designs are disclosed.
