Touch screen panel with integral wiring traces

A touch panel comprising:

• a 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;
• and
• a trench in the resistive layer between the wire trace pattern and the edge electrode pattern to electrically isolate the wire trace pattern from the edge electrode pattern.

A method of manufacturing a touch panel, the method comprising:

• coating an insulative substrate with a resistive layer;
• apply a pattern of conductive edge electrodes to the resistive layer and applying a conductive wire trace pattern to the resistive layer;
• removing the resistive layer at least between the wire traces and the edge electrodes to electrically isolate them from each other;
• applying an insulative material over both the wire traces and the edge electrodes to protect them;
• and
• co-firing the edge electrodes, the wire traces, and the insulative material all at the same time.
