1. A method of manufacturing a resistive touch screen comprising:
- providing a transparent substrate having a first surface and a second surface opposite said first surface, said transparent substrate having a first transparent conductive layer disposed on said first surface;
providing a cover sheet used as a contact layer having a second transparent conductive layer coated at a surface of said cover sheet;
spacing said cover sheet from said transparent substrate by a plurality of spacer elements and with said second transparent conductive layer opposing said first transparent conductive layer of said transparent substrate; and
providing a grounded electromagnetic interference shield at said second surface of said transparent substrate after oxidizing, said first transparent conductive layer and before reducing said first transparent conductive layer, said grounded electromagnetic interference shield comprising a third transparent conductive layer.

Abstract
A touch screen and method for manufacturing a touch screen includes a transparent substrate having a first surface and a second surface opposite the first surface. The transparent substrate has a first transparent conductive layer disposed on the first surface. A cover sheet is spaced from the substrate by a plurality of spacer elements and has a second transparent conductive layer coated at a surface of the cover sheet and opposed to the first transparent conductive layer. An electromagnetic interference shield is disposed at the second surface of the transparent substrate. The electromagnetic interference shield includes a third transparent conductive layer.
