ABSTRACT:
There is provided an in-line color picture tube apparatus with a dynamic convergence correction device. Dynamic convergence correction means is disposed between a self-convergence deflection yoke and a static convergence correction magnet assembly which are mounted on the neck portion of the tube. The dynamic convergence correction means comprises a support member made of a non-magnetic substance, eight coil assemblies having cores fixedly disposed on the support member concentrically of the tube axis with mutual equal circumferential spacings, and coils wound on the cores. The coils are connected in such a manner as to generate a four-pole magnetic field having a horizontal axis, a six-pole magnetic field having the horizontal axis, four-pole magnetic field having an axis making an angle of 45.degree. with respect to the horizontal axis, and a six-pole magnetic field having a vertical axis. Dynamic convergence correction signals of predetermined amplitude and direction are fed to the coils at predetermined timings in accordance with the deflection synchronizing signal.
