Deflection yoke

Abstract

A deflection yoke having a capability of correcting a lateral inner pincushion distortion with a magnetic field generated by a deflecting coil itself is provided. The deflection yoke includes a saddle-type vertical deflecting coil including a screen side bend portion, a neck side bend portion and a cone portion connecting the screen side bend portion and the neck side bend portion and is installed to a cathode ray tube. When viewing the screen side bend portion of the vertical deflecting coil from a screen side of the cathode ray tube in a direction along the tube axis, a distance between the screen side bend portion and the tube axis is the minimum at a portion close to a diagonal direction of the screen. As a result, the lateral inner pincushion distortion can be corrected with a magnetic field generated by the deflecting coil itself with a simple configuration, without adding any component for correcting the distortion and increasing a deflecting power.
