ABSTRACT:
Inner specular reflection is suppressed in a flat faceplate for use in a color cathode ray tube (CRT) by forming a flat glass faceplate to have an aft, or inner surface characterized by an undefined roughness. By allowing for an aft surface of undefined roughness, a subsequent lapping process is utilized to produce a predetermined roughness of the aft surface that will substantially eliminate specular reflection from that surface.
