Abstract: A self-converging color television display system utilizes a saddle-toroid deflection yoke. The length of the horizontal coil conductors adjacent the flared picture tube portion is limited to reduce stored energy. The length of the core also is limited and disposed longitudinally between the end turns of the horizontal saddle coils at a position to mitigate convergence trilemma as well as North-South pincushion distortion.

Abstract: RCA 73,015 DEFLECTION YOKE WITH PERMANENT MAGNET RASTER CORRECTION A deflection yoke of the self-converging type utilizing pincushion-shaped horizontal and barrel-shaped vertical deflection fields for converging three in-line electron beams includes magnets disposed near the top and bottom beam exit end of the yoke and respectively poled to produce flux of the same polarity as the vertical deflection field at the top and bottom portions of the raster. A second pair of magnets disposed inside the flared inner surface of the yoke at the top and bottom approximately at the center of the yoke length are respectively poled for producing flux which is of the opposite polarity of the vertical deflection field at the top and bottom portions of the raster, the two pairs of magnets cooperating with the deflection field for correcting North-South pincushion distortion with substantially no effect on the beam convergence.

Abstract: A large-screen wide-deflection angle color picture tube utilizes three coplanar electron beams. Convergence of horizontal lines on the picture tube viewing screen is accomplished by positioning a deflection yoke exhibiting particular astigmatism characteristics relative to the electron beams of the picture tube. Convergence of vertical lines is accomplished by energizing quadrupole magnetic field producing windings disposed about the picture tube neck at a vertical scanning rate.

Abstract: A color television display system is described which requires no dynamic convergence apparatus for small and medium size screen color picture tubes and which requires relatively simple dynamic convergence apparatus for large screen color picture tubes. The color picture tube includes an electron gun assembly for producing three adjacent horizontal in-line coplanar beams. The electron gun assembly includes a common three-aperture beam forming electrode for establishing precise alignment of the beams. The beams are substantially converged at all points in the scanned raster as they are deflected by a deflection yoke providing negative horizontal isotropic astigmatism and positive vertical isotropic astigmatism. The gun assembly includes magnetic shield members disposed around the two outside beam paths to shield those beams from a portion of the deflection field so that the rasters scanned by the three beams are of the same size. In addition, the color picture tube includes a faceplate having repeating groups of three different color phosphor strips and an aperture mask including a plurality of elongated slit apertures disposed adjacent the phosphor strips to enhance the light output from the picture tube.
