Abstract

A deflecting coil system for a cathode-ray tube has a coil for one direction of deflection made up of two halfcoils toroidally wound on diametrically opposite sides of a cylindrical magnetic core, each half-coil comprising diverging packages of turns I, II, with the degree of divergence being computed at each cross-sectional plane to satisfy a magnetic field strength relation given in the Specification and so to obtain an inhomogeneous field converting for coma, astigmatism and other errors of the image field. The turns in each package are parallel to one another and corresponding turns of the two packages are wound successively so that all the turns are wound in a continuous winding operation. The coil for the other direction of deflection is preferably aircored and fitted inside the magnetic core. The coil system may be used in colour television display tubes of the indexing, Lawrence or 3-gun shadow mask types or in black-andwhite display tubes in which an elliptical spot is used to eliminate the line structure.
