Improvements in the RCA Three-Beam Shadow-Mask Color Kinescope

This paper describes the advances made by RCA in the development of a production design for an all glass shadow-mask color kinescope. The constructional features of the early RCA shadow-mask color kinescope are reviewed briefly, and recent improvements in tube construction are described. These improvements contribute both to improved tube performance and to a simplification of fabrication and assembly operations. Specific constructional and processing advances are discussed.
