HIGH DURABILITY TOUCH SCREEN AND METHOD FOR MANUFACTURING
First Claim
1. A method of manufacturing a touch screen, said method comprising:
- providing a first substrate having a substantially transparent conductive coating on a surface thereof;
providing a sheet of glass, said glass sheet having a thickness of less than or equal to approximately 0.3 mm;
depositing a substantially transparent conductive film on a surface of said glass sheet;
depositing at least one functional coating at at least one surface of said glass sheet, said at least one functional coating comprising at least one of an anti-glare coating, a diffuser surface coating, an anti-reflective coating and an anti-abrasion coating;
cutting at least one glass substrate from said coated glass sheet; and
assembling said glass substrate to said first substrate to form a touch screen device.

Abstract
A method for manufacturing a touch screen that deposits a conductive layer or coating directly onto a surface of a sheet or ribbon or roll of thin glass material. The coated thin glass material may be cut to the desired shape or substrate for use as the outer, thin glass substrate of the touch screen device. Spacer elements and/or other functional coatings or layers or the like may also be applied to the conductive layer or opposite surface of the thin glass ribbon. Optionally, a functional coating or layer may be deposited or applied to a surface of a pre-cut thin glass substrate. The coated pre-cut thin glass substrate may be used as a top sheet for lamination as the protective top sheet of a touch screen device.
