Processes for forming transparent substrate with diffuser surface

A method of forming a diffuser coating on a transparent substrate, said method comprising:

• spraying at least one layer of a metal oxide precursor solution onto a transparent substrate to form a preliminary coating;
• at least partially densifying said preliminary coating;
• spraying a further layer of a metal oxide precursor solution onto said preliminary coating;
• and
• firing said preliminary coating and said further layer at a temperature in the range of from about 250° C. to about 600° C. to form a diffuser surface coating on said transparent substrate having a thickness of less than about 3 microns, a gloss reading in the range of about 30 to about 80 gloss units, and a resolution in the range of about 3 lines to about 15 lines per millimeter;
• and
• overcoating said diffuser surface coating on said transparent substrate with a transparent conductor coating.

A method of forming a diffuser coating on a transparent substrate, said method comprising:

• providing a precursor solution comprising a precursor of an metal oxide dissolved in an organic solvent;
• spraying at least one layer of said precursor solution onto said transparent substrate;
• and
• firing said at least one layer at a temperature within the range of from about 250° C. to about 600° C. to form a diffuser surface coating having a thickness less than about 3 microns, a gloss reading of about 30 to about 80 gloss units, and a resolution in the range of about 3 lines to about 15 lines per millimeter.
