Abstract
Method for driving a plasma display panel, wherein a pulse of ramp-down waveform is applied to scan electrode lines between a sustain period of a last selective write sub-field and an address period of a first selective erase sub-field continuous thereto, or between the sustain period of a preceding selective erase sub-field and the address period of a next selective erase sub-field continuous thereto after the first selective erase sub-field, whereby causing more stable address discharge at a higher sustain voltage, or a lower selective erase scan voltage.
Claims18
A method for driving a plasma display panel (PDP) having 3-electrodes comprising:
- a first step of applying a pulse of ramp-down waveform between a sustain period of a first sub-field and an address period of a second sub-field continuous to the sustain period of a first sub-field;
- and
- a second step of applying selective scan pulses in the address period of the second sub-field for turning off discharge cells.
A method for driving a PDP having 3-electrodes, comprising:
- a first step of applying a pulse of ramp-down waveform to scan electrode lines between a sustain period of a last selective write sub-field and an address period of a first selective erase sub-field continuous to the last selective write sub-field;
- a second step of synchronizing selective scan pulses to each other for turning off discharge cells in the address period of the first selective erase sub-field, and applying to scan electrode lines and sustain electrode lines, respectively;
- a third step of applying a sustain pulse to the scan electrode lines and the sustain electrode lines alternately in the sustain period of the first selective erase sub-field, for causing sustain discharge at discharge cells not turned off in the address period;
- and
- a fourth step of applying one more pulse of ramp-down waveform to the scan electrode lines between the sustain period of the first selective erase sub-field and the address period of the second selective erase sub-field continuous to the sustain period of the first selective erase sub-field.
