Zusammenfassung:Colour display tube system comprising an electron gun (5) producing three co-planar, non-convergent electron beams, and an element producing convergence (14) arranged at a distance from the electron gun, coaxially with the longitudinal tube axis. This element particularly generates a static 45 DEG 4-pole field. This combination of measures leads to an improvement of the spot quality.
