Abstract (en)

[origin: US2002118155A1] There is proposed a circuit arrangement for the actuation of a VFD, LED or LCD display, which has at least two control blocks for producing control signals for the various kinds of display, wherein the control signals of the control blocks are processed by a common driver component and the driver component transmits suitable actuation signals to the terminals of the VFD, LED or LCD display.

Abstract (de)

Es wird eine Schaltungsanordnung (1) zur Ansteuerung einer VFD-, LED- oder LCD-Anzeige (2) vorgeschlagen, welche mindestens zwei Steuerblöcke (7,8) zur Erzeugung von Steuersignalen für die verschiedenen Anzeigearten aufweist, wobei die Steuersignale der Steuerblöcke von einem gemeinsamen Treiberbaustein (11) verarbeitet werden und der Treiberbaustein entsprechende Ansteuersignale an die Anschlüsse der VFD-, LED- oder LCD-Anzeige (2) weitergibt. <IMAGE>
