Abstract
In a cathode-ray tube wherein the electrical connection between a conductive metal body attached to and having a surface contiguous with a surface of the envelope and a conductive layer on that surface is assured by a conductive stripe contacting the body and the layer, the stripe consists essentially of a minor proportion of glass and a major proportion of at least one metal selected from the group consisting of tin, lead and indium.
Claims3
A cathode-ray tube comprising an evacuated glass envelope including a funnel, a neck integral with said funnel, a faceplate sealed to said funnel, and a luminescent layer on the interior surface of said faceplate, a conductive layer adhered to at least a portion of the interior surface of said envelope, a conductive metal body attached to said interior envelope surface, and a conductive coating contacting both said layer and said metal body, said conductive coating consisting essentially of tin metal and about 2 to 5 weight percent of denitrified glass.
