Deflection apparatus and cathode ray tube with the deflection apparatus

摘要

Provided is a cathode ray tube having a deflection apparatus that can precisely correct a screen distortion caused by mis-convergence of electron beams. The deflection apparatus includes horizontal and vertical deflection coils, and a separator disposed between the horizontal and vertical deflection coils. At least one of the horizontal and vertical deflection coils comprises main deflection portions having respective first ends close to a neck and respective second ends close to a panel, a first flange portion interconnecting the first ends, and a second flange portion interconnecting the second ends. The second flange portions includes a plurality of sections spaced apart from each other, and at least one of the sections is indented from a reference line defined in a circumferential direction of a cone portion toward the first flange portion.
