Cathode ray tube and an envelope therefor

Abstract

A color cathode ray tube includes a vacuum envelope including a panel having a single glass faceplate including an inner surface and central axis and a skirt extending from the faceplate, a rear metal plate hermetically connected to the skirt through a first connecting member, a plurality of funnels coupled to the rear plate through a second connecting member, and a plurality of necks respectively extending from the funnels. In the vacuum envelope, are provided a plurality of electron gun assemblies respectively received in the necks for emitting a plurality of electron beams, a screen formed on the inner surface of the faceplate for emitting visible light by excitation of the electron beams from the electron gun assemblies, and a mask received in the vacuum envelope so as to face to the screen and having an effective region for allowing passage of the electron beams to impinge on the screen. The first connecting member has stabilizing means for absorbing strain caused by difference between a thermal expansion amount of the rear plate and that of the panel.
