ABSTRACT:
A deflection yoke assembly for use on a cathode ray tube including an evacuated envelope, a coil separator mounted exteriorly on the evacuated envelope at a location corresponding to the boundary betweeen the funnel section and the neck section and having a generally conical portion, a radially outwardly flanged front end portion at one end of the conical portion and a radially outwardly flanged rear end portion at the opposite end of the conical portion, a pair of horizontal deflection coils and a pair of vertical deflection coils both wound on the coil separator. The deflection yoke assembly comprises a vertical deflection distortion correcting unit including two electromagnetic coil devices mounted on at least said radially outwardly flanged front end portion of the coil separator in alignment with a vertical axis of the evacuated envelope while spaced 180.degree. circumferentially about the longitudinal axis of the envelope. The electromagnetic devices are adapted to generate magnetic fluxes in a direction substantially perpendicular to the vertical axis when electrically energized in synchronism with the cycle of vertical deflection, exercised by the vertical deflection coils, for minimizing raster distortions.
