Abstract

La présente invention concerne le réglage des convergences des écrans à tube cathodique pour télévision en couleur. Les réglages de pureté, de correction verticale du coussin et de correction statique de convergence sont effectués par l'intermédiaire d'aimants permanents 1 à 8 disposés à l'intérieur du col du tube 9. L'aimantation de chacun de ceux-ci est réglée en usine au moyen d'une carcasse 19 coulissable sur ledit col. Une fois les réglages effectués, cette carcasse est retirée puis réutilisée pour régler un autre tube. L'invention trouve son application dans la fabrication des écrans à tube cathodique pour télévision en couleur.
