Abstract

PURPOSE:To improve a cross pattern easily by driving multiple deflecting coils with different deflecting currents. CONSTITUTION:A deflecting device is constituted of a saddle toroidal coil, a vertical deflecting coil is constituted of a toroidal coil 15 wound on a ferrite core 18, a horizontal deflecting coil is constituted of two pairs of saddle coils 16, 17 with different magnetic field distribution in the tube axis direction and wound in the toroidal coil. The coil 16 has the positive cross convergence characteristic when combined with the coil 15. The coil 17 has the negative cross convergence characteristic when combined with the coil 15. If a current IC is fed to the first saddle coil 16 and a current IB different from IC is fed to the saddle coil 17, the good convergence characteristic can be obtained over the whole color picture tube.
