Abstract:
A cathode ray tube comprising:a panel with a screen; a funnel connected to the panel, having a cone portion and a neck portion; an electron gun in the neck portion; an implosion band located at a contact area between the panel and the funnel to prevent implosion of the cathode ray tube; a deflection yoke installed around the cone portion; an external electrically conductive layer disposed on an external surface of the cone portion; an indium tin oxide layer disposed on an outer surface of the screen, electrically connected to the implosion band and to the external electrically conductive layer, and having a sheet resistivity greater than 1Ã—105 &OHgr;/cm2 and not more than 9Ã—105 &OHgr;/cm2; and an electrically conductive ground portion strip comprising an insulating film and an electrically conductive adhesive layer on a surface of the insulating film, electrically connected to the external electrically conductive layer, attached to the cone and neck portions of the funnel, disposed between the cone portion of the funnel and the deflection yoke, and extending from the neck portion of the funnel to the cone portion.
