Abstract

Die Erfindung bezieht sich auf eine Anordnung zur Ansteuerung einer Anzeigevorrichtung mit Spalten und Zeilen, bei der den Zeilen und Spalten der Anzeigevorrichtung Spannungen in Abhängigkeit darzustellender Daten zuführbar sind. Weiter bezieht sich die Erfindung auf eine Anzeigvorrichtung mit einer derartigen Anordnung.The invention relates to an arrangement for driving a display device with columns and rows, in which the rows and columns of the display device voltages in accordance with darzustellender data can be fed. Further, the invention relates to a display device with such an arrangement.

Um eine effektive Energieausnutzung zu ermöglichen und Ungenauigkeiten zu vermeiden, wird eine Anordnung zur Ansteuerung einer Anzeigevorrichtung mit Spalten und Zeilen vorgeschlagen, bei der den Zeilen und Spalten der Anzeigevorrichtung (2) Spannungen (Vcol, Vcol/2, Vss, Vrow+, Vrow-) in Abhängigkeit darzustellender Daten zuführbar sind und die Anordnung wenigstens eine Spannungsteilereinheit (12) und eine Spannungsvervielfachereinheit (11) aufweist und bei der vorgesehen ist, der Spannungsteilereinheit eine Versorgungsspannung (Vdd) zuzuführen und eine aus der Spannungsteilereinheit abgeleitete Teilspannung einer Spannungsvervielfachereinheit zuzuführen und die Teilspannung und die durch die Spannungsvervielfachereinheit erzeugte Spannung der Anzeigevorrichtung zuzuführen.
