ABSTRACT:
A connective improvement disposed on the exterior of a cathode ray tube includes the metallic fracture-protective member peripherally surrounding the panel as an integral part of the circuitry connecting the exterior coating on the funnel portion of the tube envelope with appropriate grounding circuitry in the chassis. A discrete deposition of connective conductive material is applied to the exterior of the funnel and panel areas, whereof the funnel disposed section has the exterior funnel coating overlaid thereon. The opposed panel-disposed section makes positive connection with the peripheral protective member, which in turn, has a connective element associated therewith to complete the grounding circuitry without disturbing the intervening conductive material or the funnel coating associated therewith.
