Title: IMPLOSION-RESISTANT CATHODE RAY TUBE ENVELOPE
Abstract:
A glass envelope for a cathode ray tube (10) and a method of production. The envelope comprises (12) a panel member having a thickness (t) that is defined by an equation which involves net tensile stress; wherein the panel having a net tensile stress not exceeding 1150 psi, having a surface compression induced during panel manufacture, and having an implosion protection band (30) shrink-fitted around a skirt (20) on the panel that augments surface compression in the panel (12), whereby the panel thickness is substantially less than that of a corresponding untreated tube envelope.
