TRANSPOSED BI-DIRECTIONAL SCANNING IN A CATHODE RAY TUBE

A video display includes a transposed scanning system. The transposed scanning system utilizes sinusoidal scanning to provide bi-directional scanning along a short axis of a display screen of a cathode ray tube. Therefore, the more difficult to achieve, higher-frequency scan task is assigned to the...

Zusammenfassung:	A video display includes a transposed scanning system. The transposed scanning system utilizes sinusoidal scanning to provide bi-directional scanning along a short axis of a display screen of a cathode ray tube. Therefore, the more difficult to achieve, higher-frequency scan task is assigned to the short axis requiring the least deflection energy. L'invention concerne un affichage vidéo comprenant un système de balayage transposé. Ce système de balayage transposé met en oeuvre un balayage sinusoïdal pour obtenir un balayage bidirectionnel le long de l'axe court du dispositif d'affichage d'un tube cathodique. Ainsi, la tâche de balayage la plus difficile à exécuter et de plus haute fréquence est attribuée à l'axe court nécessitant le moins d'énergie de déviation.
