Abstract
A front assembly for a tension mask color cathode ray tube comprises a faceplate having an inner surface thereon for receiving a pattern of luminescent phosphor elements. A foil mask is supported in tension by the faceplate and has a pattern of apertures registered with the pattern of phosphor elements. The assembly is characterized by the faceplate having registration affording means disposed on the external periphery of the faceplate outside the tube vacuum enclosure constructed and arranged to permit repeatable precise registration between said foil mask and said faceplate to facilitate screening the pattern of phosphor elements upon the faceplate inner surface. By having the registration affording means located externally of the tube enclosure, the viewable area of the inner surface is maximized and the faceplate size for a given screen area is reduced.
