Abstract
A cathode-ray tube comprises an evacuated envelope with a substantially rectangular faceplate panel and implosion protection structure disposed around the periphery of the panel to apply a compressive force thereto. The implosion protection structure includes a tube-contacting portion and an overlapping portion extending at least partially along the tube-contacting portion to provide a double thickness of material to increase the effective cross-sectional area of the implosion protection structure. The implosion protection structure is improved by at least one opening formed through one of the portions thereof. Mounting lugs overlie the opening in the one portion of the implosion protection structure and are secured to the other portion of the structure bounded within the opening. A method of securing the mounting lugs also is disclosed.
