Abstract

Die Schaltungsanordnung dient der Spannungsversorgung der Zeilen- und Spaltentreiber einer Flüssigkristallanzeigevorrichtung. Sie beinhaltet einen Spannungsteiler (1) mit einer Vielzahl von in Serie geschalteten Widerständen (R1-R5) und mit zwischen den Widerständen (R1-R5) angeordneten Spannungsabgriffen (22-25) zum Abgreifen unterschiedlicher Spannungspegel (V2-V5). Ein einziger (25) der Spannungsabgriffe (22-25) ist mit Mitteln (3) zur Feineinstellung des dort abgegriffenen Spannungspegels (V5) ausgestattet. Durch einmalige individuelle Kalibrierung eines jeden Exemplars der Schaltungsanordnung kann der eine Spannungspegel (V5) derart fein eingestellt wcrden, dass ein durch asymmetrische Spannungspegel verursachtes Übersprechen, d. h. gegenseitige Wechselwirkung von Bildpunktinhalten, vermindert wird. Die Vorteile der Schaltungsanordnung kommen besonders zu Geltung, wenn sie in Flüssigkristallanzeigevorrichtungen mit Graustufenanzeige oder Farbanzeige eingesetzt wird.
