Abstract

Bei einer flachen Anzeigeeinrichtung sind in Zeilenrichtung verlaufende Kathodendrähte (K1 - K5) vorhanden, die nur zeit­ weilig auf Emission geschaltet werden. Zeilenelektroden (L1 - L10) werden zu Gruppen zusammengefaßt, wobei alle Zeilenelek­ troden innerhalb einer Gruppe über einen einzigen Anschluß an­ gesteuert werden. Der Abstand benachbarter Zeilenelektroden innerhalb einer Gruppe ist größer als die Höhe des Bereichs, der von Elektronen aus emittierenden Kathodendrähten überdeckt wird. Dadurch lassen sich Elektronen zeilenweise mit nur weni­ gen Ansteuerleitungen steuern. Zum Synchronisieren der Poten­ tiale an die Kathodendrähte und die Zeilenelektroden ist eine Kathoden/Zeilenelektroden-Synchronisierschaltung (15) vor­ handen.
