Abstract
There is disclosed a method and apparatus of driving a plasma display panel that is adaptive for reducing discharge delay upon reset discharge. A driving method and apparatus of a plasma display panel according to an embodiment of the present invention applies a plurality of pulses to the plasma display panel for the reset period in order to reduce a discharge delay.
Claims61
A driving method of a plasma display panel having address electrodes, a scan electrode and a sustain electrode, wherein one frame is divided into a reset period, an address period and a sustain period, the method comprising:
- applying a rising waveform to the scan electrode during the reset period, the rising waveform starting from a first voltage greater than a ground voltage;
- and
- applying at least one first pulse to the address electrodes of the plasma display panel during the reset period, wherein the at least one first pulse applied to the address electrodes is applied during a setup time of the reset period.
