Patent ID: 8203550

Claim:
A plasma display, comprising: a plasma display panel including cells and display electrodes including a group of X electrodes and a group of Y electrodes; an X electrode driving circuit configured to apply a sustaining pulse to the group of X electrodes; and a Y electrode driving circuit configured to apply a sustaining pulse to the group of Y electrodes; wherein the X electrode driving circuit and the Y electrode driving circuit are configured to apply the sustaining pulses to the display electrodes to cause sustaining discharge for a number of times corresponding to luminance of the cells to be caused to emit light and thereby to form an image on the plasma display panel; one of the X electrode driving circuit and the Y electrode driving circuit is configured to apply a low-voltage sustaining pulse with a peak value not large enough to cause the sustaining discharge by itself to a corresponding one of the group of X electrodes and the group of Y electrodes; the other one of the X electrode driving circuit and the Y electrode driving circuit is configured to apply a high-voltage sustaining pulse with a peak value large enough to cause the sustaining discharge by itself to the other one of the group of X electrodes and the group of Y electrodes; and in a predetermined time period, the X electrode driving circuit and the Y electrode driving circuit are configured to apply the low-voltage sustaining pulse and the high-voltage sustaining pulse at the same time to the corresponding display electrodes.
