FARBANZEIGEVORRICHTUNG MIT ANORDNUNG ZUR KORREKTUR VON LANDUNGSFEHLERN

摘要

A color display device including a shadow mask and a correction deflection system for correcting landing-errors. The correction deflection system comprises first and second correction deflection devices which are arranged one behind the other in the direction of the electron beams and are energizable in opposite senses so that the first correction deflection device generates a dipole field deflecting the three electron beams away from the longitudinal tube axis, and the second correction deflection device generates a dipole field deflecting the three electron beams towards the longitudinal tube axis, or conversely.
