ABSTRACT:
A plasma display panel having cathodes, anodes and trigger electrodes wherein the trigger electrodes correspond to a plurality of discharge electrodes which are sequentially scanned and wherein an insulating layer separates the trigger electrodes and the discharge electrodes and where a constant trigger voltage is supplied until the plurality of discharge electrodes corresponding to the trigger electrode have been activated. In the invention, the trigger voltage is quickly changed and is then returned to an intermediate level within the varied potential difference and the frequency of a trigger voltage pulse is reduced to one by the number of block discharged electrodes so that the power consumption of the trigger electrodes is greatly reduced and since the trigger voltage is returned to an intermediate level erroneous discharges will not be generated between inactive trigger electrodes and the other discharge electrodes to which data voltage pulses are supplied thus producing a high definition display.
