  • External neck charge dissipation means for an in-line color cathode ray tube
    Patent number: 4564786
    Abstract: The invention provides efficient means for dissipating deleterious charge build-up in the glass neck portion of a color cathode ray tube employing an in-line plural beam electron gun assembly. In one embodiment, the invention is comprised of two longitudinal stripes of electrical conductive material oppositely applied on the neck substantially over both narrow sides of the gun assembly. Connective conductors join the stripes to the grounded funnel coating to provide for dissipation of the charge. In another embodiment, the longitudinal stripes are joined by two band-like layers encompassing inter-electrode spacings of the gun assembly.
