A new driving waveform is proposed to improve the luminous efficiency of alternating current (ac) plasma display panel with a large sustain gap (400 /spl mu/m) structure under a high Xe (15%) gas mixture. Due to the large sustain gap structure, the reset waveform was modified based on Vt close curve analysis to produce the surface discharge between the scan and sustain electrodes by applying the negative bias voltage on the sustain electrode during a ramp-up period. During a sustain period, the sustain waveforms with two different voltage polarities, i.e., positive and negative voltage levels, were applied, thus resulting in producing an efficient discharge by accumulating the wall charges uniformly among the three electrodes. As a result of adopting the proposed driving waveform, the luminance of 330 cd/m/sup 2/ and luminous efficiency of 4.5 lm/W under the sustain voltage of 210 V and the trigger voltage of 160 V were obtained in the 6-in plasma display panel (PDP) with green phosphors under a large sustain gap (400 /spl mu/m) and a high Xe (15%) gas mixture.
