Abstract
A deflection yoke for a cathode-ray tube of a video display, includes a pair of horizontal deflection windings and a pair of vertical deflection windings. The pair of vertical deflection windings includes a saddle-shaped winding. The saddle-shaped winding includes a front end winding portion, close to a screen of the cathode ray tube, a rear end winding portion, remote from the screen and a pair of side winding portions, between the front and rear end portions. The saddle-shaped winding is disposed generally symmetrically with respect to a plane of symmetry. A depression or notch is formed in the front end winding portion for varying a winding distribution locally. The depression or notch forms asymmetry with respect to the plane of symmetry.
