Abstract: Electromagnetic deflection unit for color cathode-ray tubes, comprising a pair of horizontal deflection coils and a pair of vertical deflection coils, the saddle-shaped vertical deflection coils having a rear bundle on the electron-gun side and a front bundle located on the screen side, lateral conductor harnesses 120 connecting the two bundles so as to produce a main window in the intermediate region lying between these said bundles, the conductor harnesses being arranged so that, at the end of the main window 18, on the gun side, at least 98% of the lateral harness conductors lie within an angular aperture &THgr;m of between 60 and 80°. This arrangement of the conductors in the rear part of the window makes it possible to minimize the aberrations due to coma parabola so as to avoid the use of additional field shapers.

Abstract: A flat cathode ray tube includes a front panel having an inner phosphor screen with a plurality of phosphor pixels and an inner edge side, a solid glass frame having a front side and a rear side, and a tensioned mask having a plurality of beam-guide holes corresponding to the phosphor pixels on the phosphor screen and an edge portion. The front panel is formed with a substantially flat shape. The front side of the solid glass frame is sealed to the edge side of the front panel. The edge portion of the tensioned mask is immersed in the solid glass frame. A funnel mounting a deflection yoke therearound and having a neck mounting an electron gun therewithin is sealed to the rear side of the glass frame. The phosphor screen of the front panel is formed by using a printing method.
