Abstract
A deflection yoke for a television picture tube utilizing coplanar horizontal in-line electron guns includes vertical and horizontal coil windings selected for producing positive vertical isotropic astigmatism and negative horizontal isotropic astigmatism which underconverges the electron beams along the vertical deflection axis such that the beams are substantially converged at all points on a scanned raster of the picture tube. The desired convergence characteristics are achieved by winding the vertical and horizontal coil conductors such that the conductor distribution in each quadrant of a cross-section of the yoke is least in a region between 25 DEG and 45 DEG measured from the vertical deflection axis of the yoke.
