Abstract
(DE)
Aufgabe ist es, bei einer inline-Farbbildröhre die Ablenkempfindlichkeit zu erhöhen. Der Querschnitt des Röhrenhalses (6) im Bereich der Ablenkspulen (12) ist von der Kreisform abweichend etwa dem Breit/Höhe-Verhältnis des Bildschirms (2) angepaßt ausgebildet. Insbesondere für inline-Farbbildröhren mit 16:9 Bildschirm.
(EN)
To increase the deflection sensitivity in an inline colour television tube, the cross-section of the tube neck (6) in the region of the deflection coils (12) deviates from the circular so that it conforms approximately to the width/height ratio of the picture screen (2). In particular for inline colour television tubes with a 16:9 picture screen.
(FR)
La tâche consiste à augmenter, dans un tube image en couleurs de type in-line, la sensibilité de balayage. La section du col du tube (6) au voisinage des bobines de balayage (12) est dimensionnée de manière à s'éloigner de la forme circulaire et à s'approcher sensiblement du rapport largeur/hauteur de l'écran (2). Ceci convient en particulier aux tubes image en couleurs du type in-line pour écran 16:9.
