Title: Colour television deflection yoke having reduced variation in beam trio distortion
IPC: H01J29/76
Filed: 1971-11-26
Abstract: 1376917 Electron beam magnetic deflection system RCA CORPORATION 26 Nov 1971 [4 Oct 1971] 55051/71 Heading HID A toroidal deflection yoke for a delta gun shadow mask colour TV picture tube (e.g. wide angle type), comprises interleaved horizontal and vertical coil winding portions, the portions having their conductor distribution selected to effect substantially zero yoke induced beam trio distortion in the corners of the scanned area and to substantially minimize variation in beam trio distortion ratios around the edge of the scanned area. Fig. 5, illustrates such a winding distribution for connection as in Fig. 6 (not shown). A yoke exhibiting isotropic but no anisotropic astigmatism may be symmetrical or asymmetrical as in Specification 1,299,491 and Specification 1,373,524, and modified, generally emperically, to produce the minimized variation between beam trio distortion ratios. On axis radial dynamic convergence correction is obtained by three electromagnets (e.g. 19, 19a, Fig. 1, not shown). Instanced is the greater reduction of shadow mask aperture sizes along the PS positions (Fig. 3, not shown), than the even numbered positions and the compensating yoke may be wound to minimize variation of beam trio distortion ratios on the PS axes and to weight the ratio between the PS and S axes to allow larger than normal apertures around the screen edge. Fig. 4 (not shown), illustrates beam trio distortion for prior art yokes exhibiting substantially no anisotropic but some isotropic astigmatism, while Fig. 7 (not shown), illustrates the observed distortion produced by a corrected yoke. "Crowding" and "degrouping" effects as well as yoke induced effects are considered.
