Abstract: Disclosed is a deflection yoke having function of self-correction of inner pin distortion. More than one screen sub bent of the deflection yoke are formed between the screen bent of the deflection coil and the reference line, for improving inner pin distortion of the screen. Additionally, a section part for connecting the screen bent with the screen sub bent improves inner pin distortion of the screen together with the screen sub bent. The deflection yoke having function of self-correction of inner pin distortion does not use an additional circuit for suppressing pincushion as was in the related art, thereby reducing productivity costs, reducing power dissipation as well.
