    摘要: In a color picture tube apparatus having a first auxiliary deflecting means (GD1, GD2) for deflecting a single electron beam, emitted from a cathode (K), in a direction to separate from the tube axis (Z) in synchronism with switching among a plurality of video signals supplied to an electron gun, and splitting the single electron beam substantially into a plurality of beam segments, and a second auxiliary deflecting means, disposed between the first auxiliary deflecting means (GD1, GD2) and a main deflecting unit, for deflecting the plurality of beam segments in a direction to come close to the tube axis, the first auxiliary deflecting means (GD1, GD2) is constituted by an electrostatic deflecting lens provided to an accelerating electrode system between a control electrode (G1) and a focusing electrode (G4) of the electron gun, and the second auxiliary deflecting means is constituted by a main electron lens (ML) of the electron gun for finally focusing the electron beam segments on a phosphor screen. Accordingly, the entire length of the picture tube can be shortened, and the auxiliary deflecting power can be reduced as well as the manufacturing cost.

    摘要: A color cathode ray tube with a shadow mask has a screen partitioned into a plurality of elemental screen areas and electron guns positioned and corresponding to the respective elemental screen areas, the electron guns generating electron beams to scan the screen. The shadow mask includes effective regions having a number of apertures passed through by the electron beams to impinge on the screen and a non-effective region adjacent to the effective regions. Phosphors as a signal source are deposited on the non-effective regions or the boundaries between the elemental screen areas to emit a light signal by electron beam excitation. A photo-electric transducer is provided facing the shadow mask and to detect the light signal for feed back to a deflection system to control the electron beam deflection.

    摘要: A colour cathode ray tube (11) includes a screen (15), a shadow mask and an electron gun section. The electron gun section comprises a plurality of separate unit electron guns (27,29,33). The screen is divided into a plurality of subregions (73,75,77,79) each of which is scanned by an individual unit electron gun. Each unit electron gun emits a single electron beam and in associated with an individual main deflection device for causing the beam to scan the electron gun's particular subregion of the screen and subsidiary deflection means (45,47,51) for effecting electron beam colour switching.

    摘要: In a color cathode ray tube, single electron beam (15) is emitted from a cathode (22) of an electron gun (6) and is electrostatically deflected by electrodes (26A, 26B) in a predetermined cycle so that the electron beam (15, 16, 12) is deflected at three stages and three apparent electron beams (15, 16, 17) are directed in different directions. The three apparent electron beams (15, 16, 17) are deflected by a supplement coil (14), thereby correcting the convergence. The three electron beams (15, 16, 17) are deflected by main deflection coils of yoke (7), passes through an aperture of a shadow mask (8) and are landed on a phosphour stripes (10) of a screen (2) formed on a face plate.
