Abstract:
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 250Â° 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.
