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.
