  • Patent number: 6218773
    Abstract: A deflection yoke which can simultaneously achieve suppression of induction current arising from an influence of a raster rotation correction coil and correction of misconvergence which varies the current balance of horizontal deflection coils. The deflection yoke of the present invention includes a raster rotation coil, and a pair of coils sharing a single core and respectively connected in series to an upper side horizontal deflection coil and a lower side horizontal deflection coil. The pair of coils are connected such that the polarities thereof may be opposite to each other. The pair of coils suppress current induced by a magnetic field of the raster rotation coil. In order to apply a bias to the pair of coils which share the core, a single bias coil is wound on the shared core on which the pair of coils are wound.
