Abstract:
1. A method of driving a plasma display using a plurality of selective writing sub-fields arranged within one frame period, the plasma display including a plurality of scan electrodes, a plurality of sustain electrodes and a plurality of address electrodes, the method comprising: applying an initialization waveform to the scan electrodes in a reset period of one of the plurality of selective writing subfields, the initialization waveform including a rising waveform that increases to a setup voltage and a falling waveform that decreases to a set-down voltage; applying an initialization sustain pulse to the scan electrodes in a sustain period of the one of the plurality of selective writing sub-fields; applying sustain pulses to all cells to sustain a discharge of selected on-cells in the sustain period of the one of the selective writing sub-fields of the one frame, wherein the initialization sustain pulse has a pulse width greater than a pulse width of each of the sustain pulses or the initialization sustain pulse has a voltage greater than a sustain voltage of each of the sustain pulses; applying a first direct current bias voltage to the sustain electrodes during the reset period of the one of the selective writing sub-fields; applying a second direct current bias voltage to the sustain electrodes during an address period of the one of the selective writing sub-fields; and applying sustain pulses to the sustain electrodes during the sustain period of the one of the selective writing sub-fields.
