DEFLECTING YOKE AND CATHODE-RAY TUBE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately correct the convergence by providing any one of right and left of a rear part of a deflecting yoke with a horizontal line correcting coil and a horizontal line adjusting magnetic body and a magnetic body holder part. SOLUTION: An U-shaped magnetic body 6 for vertical auxiliary coil and a vertical auxiliary coil 7 wound around the magnetic body 6 are arranged in upper and lower of a rear part of a deflecting yoke. A bar-like magnetic body 22 for horizontal line correcting coil and a horizontal line correcting coil 23 wound around the magnetic body 22 are respectively arranged in right and left of the rear part of the deflecting yoke. In the horizontal line correcting coil 23, winding direction of each coil and current flowing direction are decided so that magnetic fields to be generated by a left side horizontal line correcting coil 23a and a right side horizontal line correcting coil 23b have the same polarity. With this structure, electron beam of B and R are moved in the vertical direction opposite to each other. A horizontal line pattern of red and blue can be corrected by adjusting the current value to be flowed to the horizontal line correcting coil 23.
