Abstract
An improved color picture tube includes a glass envelope comprising a faceplate panel, a funnel and a neck. The faceplate panel has four sides and four corners and includes a transparent rectangular faceplate, having a cathodoluminescent screen on an interior surface thereof, and a sidewall peripherally extending from the faceplate. The end of the sidewall facing the funnel has a seal land that is sealed to the funnel. The improvement comprises the sidewall seal land having a varied width around the periphery of the panel, wherein the widest portions of the sidewall seal land are located along the panel sides and the narrowest portions of the sidewall seal land are located at the corners of the panel. The width of the sidewall seal land is from 5% to 17% less in the corners of the panel than at the centers of the sides of the panel.
