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:
Reset, address, and sustain operations of a plasma display device are performed by applying a driving waveform to a scan electrode while biasing a sustain electrode at a ground voltage. Then a driving board for driving the sustain electrode may be eliminated. In addition, a discharge between the sustain electrode and the scan electrode as well as between an address electrode and the scan electrode may be ensured in an address period by accumulating positive wall charges on the sustain electrode at an end of a falling period of a reset period.

A method of driving a plasma display apparatus may include supplying a first voltage to the X electrodes during a first reset period of the reset period, supplying, using energy stored in the energy recovery circuit, a ramp waveform voltage that rises from the first voltage signal to a second voltage to the X electrodes during a second reset period of the reset period, biasing the X electrodes with the second voltage during at least a first sub-period of a third reset period of the reset period, supplying a ramp pulse waveform voltage that rises from a third voltage to a fourth voltage to the Y electrodes during a second portion of the first reset period, and supplying a ramp pulse waveform voltage that falls from the third voltage to a fifth voltage to the Y electrodes during the third reset period.
摘要:
A plasma display panel (PDP) and a method for driving the PDP, in which address data is applied to address electrodes grouped into two groups in an address period in such a manner that the address data application is carried out for respective address electrode groups at different times. Accordingly, discharge current generated due to address discharge may be distributed in terms of time, and a voltage drop occurring in the address period may be reduced.
