ABSTRACT:
A gas-discharge display panel comprising a matrix of plural pairs of display discharge cells and auxiliary discharge cells individually provided with three electrodes, one of which is common to both cells, is driven by a discharge sustaining pulse train, pairs of discharge starting pulses and pairs of discharge eliminating pulses, which pairs of pulses are applied respectively to two electrodes in the display discharge cell under the sequential application of scanning pulses to the auxiliary discharge cells and a time duration between the applications of which pairs determines the displayed brightness and further which pairs are applied at intervals of the discharge sustaining pulses with the least necessary pulse height and pulse width. As a result, a picture having sufficiently dark and bright levels can be efficiently displayed under the quick response with the least power consumption and the long life.
