IMPLOSION PROTECTION SYSTEM FOR A CATHODE RAY TUBE WITH A FLANGELESS FACEPLATE

摘要

This disclosure depicts a color television picture tube having a glass bulb including a flangeless faceplate and a funnel with a convex seal land which mates with a concave inner surface of the faceplate. The tube has an implosion protection system comprising a tension member which surrounds the faceplate in straight lines between the faceplate corners. The system is characterized by the tension member being under tension to produce radially inwardly directed force components on the faceplate corners and by a lack of significant physical containment of the edge surface of the faceplate along the sides thereof.
