ABSTRACT:
Disclosed is a method for correcting inner pin distortion generated in the CRT product and deflection yoke thereof. According to the disclosed method and deflection yoke thereof, the additional circuit for suppressing inner pin distortion phenomenon on the screen is not required as the related art, reduction in manufacturing costs is possibly achieved. Also, as the circuit for suppressing pincushion is not used, power dissipation could be reduced, and instability in dispersion and characteristics of a pin in the middle portion due to increase of dispersion generation by a wiring of a coil could be resolved.
