  • Process of fabricating a cathode ray tube
    Patent number: 4112562
    Abstract: The process includes exposing a photosensitive coating on a surface of the faceplate panel of a tube with actinic radiation passed through a patterned screen master, developing the panel coating and then mounting a formed imperforate member to the panel. A photosensitive coating on the imperforate member is exposed with actinic radiation passed through a patterned color selection electrode master while the imperforate member is mounted to the panel.
