Abstract

Eine Kathodenanordnung für eine flache Elektronenstrahl-Bild­ wiedergabevorrichtung weist eine Gegenelektrode (6), eine Mehr­ zahl zu dieser paralleler Heizdrähte (7) und eine ebenfalls zur Gegenelektrode parallele Zuganode (5) auf. Weiterhin sind Fo­ kussierdrähte (8) und Ziehdrähte (9) vorhanden, die parallel zu den Kathodendrähten verlaufen. Die Zuganode ist so ausge­ bildet, daß die zu jedem Kathodendraht jeweils mehrere Durch­ laßzeilen aufweist. A cathode assembly for a flat electron beam image Playback device has a counter electrode (6), a multiple number to this parallel heating wires (7) and also to Counter electrode parallel pull anode (5). Furthermore Fo kissing wires (8) and pulling wires (9) are present in parallel run to the cathode wires. The train anode is so out forms that to each cathode wire several through has read lines.

Dank dieser Anordnung ist es nicht mehr erforderlich, jeder Durchlaßzeile in der Zuganode einen gesonderten Kathodendraht zuzuordnen, sondern es reicht aus, jeweils einen einzelnen Kathodendraht für mehrere Durchlaßzeilen zu verwenden. Dadurch kann erheblich Heizleistung eingespart werden. Thanks to this arrangement, it is no longer necessary for everyone Pass line in the train anode a separate cathode wire assign, but it is sufficient to have a single one Use cathode wire for multiple pass lines. Thereby heating power can be saved considerably.
