Deflection unit for color cathode ray tubes

Abstract

The present invention refers to a deflection unit for mounting on a color cathode ray tube, an associated tube and a corresponding display apparatus. The deflection unit comprises a pair of coils for vertical deflection and a pair of coils for horizontal deflection. At least one of the pair of coils is subdivided into at least two parts, of which one part is intended for the correction of convergence errors and the other part for the correction of geometry errors. The respective corrections can be carried out independently of the respectively other correction. According to a preferred embodiment the parts are spatially separated and mechanically independent, with the part intended for geometry error correction being positioned closer to the screen of the picture tube. Preferred is the use of an in-line type arrangement of the saddle-saddle or saddle-toroidal type.
