Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Reduzie­ rung der Untergrundhelligkeit im unteren Bildbereich einer Gasentladungsanzeigevorrichtung. Mit diesem Verfahren soll die Reduzierung der Bildschirmhelligkeit vermieden werden. Die Erfindung sieht hierzu vor, daß das Plasma nach dem Bildende (unterem Bildbereich) rückwärts zur ersten Kathode getastet wird. Das erfindungsgemäße Verfahren wird bei flachen (Plasma-) Bildschirmen angewendet.
