More Information
Summary:A deflection yoke device comprises a convergence correction circuit connected between a vertical deflection coil and correction coils. The convergence correction circuit includes a first, second and third impedance elements connected in parallel and at least two diodes. The diodes are connected in series in the same direction and respond to a vertical deflection current of the vertical deflection coil to regulate a current flowing through the correction coils to thereby correct the YH mis-convergence.
