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. With a flat display device are in the row direction running cathode wires (K1 - K5) available, the only time be switched to emission. Row electrodes (L1 - L10) are grouped together, with all row elec occur within a group via a single connection to be controlled. The distance between adjacent row electrodes within a group is greater than the height of the area which is covered by electrons emitting cathode wires becomes. This allows electrons to be row by row with just a few control the control lines. To synchronize the pots tiale to the cathode wires and the row electrodes is one Cathode / row electrode synchronizing circuit (15) before act.
