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. The imperforate member coating is then developed and the imperforate member is etched to form an apertured color selection electrode.
