<p>A structure and method is disclosed for a routing structure for connecting the transparent conductive oxide (TCO) electrodes of a touch-sensor panel to a touch controller while providing the requisite cross-over routing. Routing is confined to the border area of a single glass panel where there is no need for transparency. By applying the TCO electrodes to the glass surface, first, and then applying the non-conducting artwork layer above them, there is no need to extend the TCO electrodes above the glass surface and, thereby, subject these thin and brittle electrodes to mechanical stress. One is able to selectively connect each TCO electrode to its intended metalized routing trace by using appropriately positioned vias in the non-conducting artwork layer, and depositing conductive plugs in those vias. The entire conductive pathway from TCO electrode to metalized routing trace is inherently much less vulnerable to failures due to mechanical stress. The method for creating this routing structure involves no new tools or processes; it makes use of existing and well-known laser patterning and screen printing technologies. By coloring the conductive via plugs to match the color of the non-conducting artwork layer, users will not see the connections to the underlying metalized routing traces.</p> |
