Patent ID: 7224329

Claim:
A plasma display apparatus, comprising: a plasma display panel equipped with first electrodes and second electrodes arranged adjacently to each other, extending in a first direction, and address electrodes extending in a second direction at a right angle to the first direction; an X sustaining circuit that supplies sustaining pulses to said first electrodes; a Y sustaining circuit that supplies sustaining pulses to said second electrodes; each of said X and Y sustaining circuits further comprising: a first output device provided between a path connected to said first or second electrodes and a high potential power supply, a second output device provided between the path connected to said first or second electrodes and a low potential power supply, the first and the second output devices respectively being connected between a path through which the sustaining pulses are supplied and a high voltage power source line, and between the path and a low voltage power source line, a power recovery circuit having a resonant circuit, formed with a display capacitor of the plasma display panel, which recovers energy when an application of the sustaining pulse is released and uses the recovered energy for a next application of the sustaining pulse; a third output device that switches a connection state of the path and the power recovery circuit to a state in which power is supplied from the power recovery circuit to the path, a fourth output device that switches the connection state of the path and the said power recovery circuit to a state in which power is recovered from the path to the power recovery circuit, a first drive circuit through a fourth drive circuit that drive the first through the fourth output devices, respectively, a first phase adjusting circuit that adjusts timing of a changing edge of a driving signal which drives said first output device; a second phase adjusting circuit that adjusts timing of a changing edge of a driving signal which drives said second output device; and a third phase adjusting circuit adjusting a time difference between a turning on of the third output device and that of the first output device, and a time difference between a turning on of the fourth output device and that of the second output device.
