1. A method of manufacturing a touch panel, the method comprising:
coating an insulative substrate with a resistive layer;
applying a pattern of conductive edge electrodes to the resistive layer and applying a conductive wire pattern to the resistive layer;
electrically isolating the conductive edge electrodes from the conductive wire traces using a laser beam to ablate the resistive material between the edge electrodes and the wire traces and the resistive material between the wire traces; and
applying an insulative material at least between the edge electrodes and the wire traces.
