摘要:
A plasma display panel and driving method thereof. Waveforms for performing a reset operation, an address operation, and a sustain operation are applied to a scan electrode while a sustain electrode is biased with a predetermined voltage, and it is controlled such that the absolute value of a positive voltage of sustain voltage pulses applied to the scan electrode in the sustain period may be greater than the absolute value of a negative voltage thereof. Further, an address electrode is floated when a waveform having a sustain discharge function is applied to the scan electrode, and the voltage at the address electrode is controlled to be increased and decreased according to the voltage at the scan electrode.

摘要:
A multiple power supply unit includes two DC stabilized power supplies that provide electrical power in parallel to a load, each power supply providing its own operation indication to the other power supply. Each power supply changes a reference voltage used to detect excess current of its own output to the load according to whether the operation indication is received from the other power supply.
