Abstract
A method of manufacturing a touch screen panel, the method including applying a resistive coating to one surface of an insulative substrate, applying an insulative protective coating to the resistive coating, depositing a conductive edge electrode pattern including a plurality of edge electrodes on the protective coating, and firing the panel until the edge electrodes etch through the protective coating and make electrical contact with the resistive coating.
