DEFLECTION YOKE

摘要

PURPOSE: A deflection yoke is provided, in which horizontal deflection coil is equipped with an auxiliary coil for adjusting convergence and distortion of electron beam, to thereby reduce parts count and cost by eliminating the necessity of using a correction member of circuit. CONSTITUTION: A deflection yoke comprises a coil separator coupled to the screen surface of CRT, and which has a neck part and a screen part; a horizontal deflection coil(20) arranged at the inner periphery of the coil separator, and which deflects electron beam in a horizontal direction; a vertical deflection coil arranged at the outer periphery of the coil separator, and which deflects electron beam in a vertical direction; and an auxiliary coil(100) arranged at the coil separator, and which adjusts convergence and distortion of electron beam deflected by horizontal and vertical deflection coil.
