First Claim
1. A method of forming an improved coated faceplate, said method comprising:
- providing a transparent substrate coated with a functional coating on at least one surface, said functional coating being selected from the group consisting of indium tin oxide, tin oxide, doped tin oxide, and doped zinc oxide;
providing a precursor solution, said precursor solution at least comprising a metal oxide precursor dissolved in an organic solvent;
coating at least one layer of said precursor solution onto said functional coating of said transparent substrate;
firing said at least one layer of said precursor solution at a temperature of at least about 250°
C. to form the faceplate having a diffuser surface coating on said functional coating of said transparent substrate, said coated faceplate having a resolution of at least about 3 lines per millimeter.

Abstract
Processes for making a transparent substrate having a glare reducing diffuser surface coating on its surface are disclosed to provide a touchscreen or a faceplate such as for attachment to a screen for a cathode ray tube or other display device. Preferably, the faceplate has at least one of a gloss reading of less than about 80 gloss units, and a resolution of at least about 3 lines per millimeter. The method includes coating at least one layer of a precursor solution onto a functional coating provided on at least one surface of the substrate, and firing the layer to form the faceplate having a diffuser surface coating on the functional coated substrate. Preferably, the precursor solution at least comprises a metal oxide precursor dissolved in an organic solvent. Also, the firing preferably occurs at a temperature of at least 250° C. The functional coating is preferably provided as a transparent conductive coating.
