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. The invention relates to a method for reducing the background brightness in the lower part of the image Gas discharge indicator. With this procedure the reduction in screen brightness should be avoided will. The invention provides that the plasma after the end of the image (lower image area) backwards to the first Cathode is touched. The method according to the invention is used for flat (plasma) screens.
