Abstract:
1. A method for driving a plasma display comprising a plurality of discharge cells, first electrodes and second electrodes for receiving sustain voltage pulses, and third electrodes between respective said first electrodes and second electrodes, the method comprises: during a sustain interval, (a) performing a short gap discharge between the first electrodes and the third electrodes during a first period; and (b) performing a long gap discharge between the first electrodes and the second electrodes during a second period, wherein the sustain voltage pulses are alternately applied to the first electrodes and the second electrodes; and during a reset interval, applying a gradually falling voltage waveform to the third electrodes to prepare the discharge cells for addressing while a first positive voltage is applied to the first electrodes and a second positive voltage is applied to the second electrodes.
