  • Patent number: 5247225
    Abstract: There is disclosed a display apparatus including a rear electrode unit, electron beam generating sources, a front electrode unit including a plurality of electron beam control electrodes laminated together with insulating spacers therebetween, and a face plate formed with a fluorescent screen. The front electrode is coupled together by first metallic coupling pins fixed on the electron beam control electrode arranged to confront the fluorescent screen. The rear electrode unit is coupled with the electrode unit by second metallic coupling pins fixed to one of the electron beam control electrodes other than the electron beam control electrode confronting the fluorescent screen.

  • Patent number: 4891552
    Abstract: An image display apparatus for displaying images on a fluorescent screen comprising plural linear cathodes, an electron beam extraction electrode with plural apertures and vertical deflection electrodes which are formed by segments. The respective segments of the vertical deflection electrodes have various shapes, and deflection voltages applied to the respective segments can be varied so that distortion of the displayed images on the fluorescent screen may be corrected.
