ABSTRACT:
A method of manufacturing a touch panel wherein a glass substrate is coated with a resistive layer; a pattern of conductive edge electrodes and a conductive wire trace pattern are applied to the resistive layer; the conductive edge electrodes are electrically isolated from the conductive wire traces; and a protective insulative border layer is applied over the edge electrodes and the wire traces. A touch panel which includes a glass substrate coated with a resistive layer on one surface thereof; a pattern of edge electrodes on the resistive layer; a wire trace pattern on the resistive layer; a trench in the resistive layer between the wire trace pattern and the edge electrode pattern; and a protective insulative border layer over the edge electrode pattern and the wire traces.
