ABSTRACT: In a matrix of diplay elements arranged in rows and columns with row scanning and column selection all dis- play elements which are connected to a scanned row conductor are always ignited, such that the non-selected display ele- ments of that row receive a low quiescent current through quiescent current supply circuits in the column selection circuits and the selected display elements a higher display current through selection circuits in the column selection circuits. The low quiescent currents reduce the ignition- voltage for the next following row to be scanned whilst yet a high contrast is produced between the selected and non- selected display elements. - 23 -
