Abstract (en)
[origin: WO2019138370A1] A multi-layer conductive coating is substantially transparent to visible light, contains at least one conductive layer that is sandwiched between at least a pair of dielectric layers, and may be used as an electrode and/or conductive trace in a capacitive touch panel. The multi-layer conductive coating may contain a dielectric layer(s), and may be used in applications such as capacitive touch panels for controlling showers, appliances, vending machines, electronics, electronic devices, and/or the like. In certain example embodiments, different electrodes of the touch panel may be formed by different silver based layers of the same or different multi-layer coatings. In patterning the electrodes, different laser scribing wavelengths may be used to pattern different respective conductive layers, of the same or different multi-layer coating(s), in certain example embodiments.
