Abstract
A display tube having a deflection coil support with a field deflection coil system at its outer side and a line deflection coil system at its inner side. The gun-sided end of the line deflection coil system is situated in a plane parallel to the wall of the display tube. The outer side of the coil support is surrounded by an auxiliary deflection coil system, preferably in a printed form, against the inner and for outer surface of a synthetic material supporting cylinder. This assembly, which can be used particularly for scan velocity modulation purposes, is at least partly arranged between the field deflection coil system and the wall of the display tube, while it partly overlaps the gun-sided end of the line deflection coil system.
