Abstract
A PDP driving method. When a first sustain pulse is applied to a scan electrode during a sustain period, an address electrode is biased by a positive voltage, or the address electrode is biased. Therefore, when a large amount of wall charges are formed on the address and scan electrodes by address discharging during an address period, no main discharge is generated since a high potential of the address electrode is formed in the sustain period.
Claims20
A plasma display device comprising:
- a plasma display panel having respective discharge cells formed between a respective sustain electrode, scan electrode, and address electrode;
- and
- a driving circuit for applying a driving voltage to the sustain electrode, the scan electrode, and the address electrode during a reset period, an address period, and a sustain period,
- wherein the driving circuit applies a second voltage to the address electrode of a discharge cell to be selected when the address electrode of discharge cells which are not selected is established to receive a first voltage, during the address period, and alternately applies a sustain pulse to the sustain electrode and the scan electrode and maintains a potential of the address electrode at a third voltage for a predetermined time, during the sustain period.
A method for driving plasma display panel for forming respective discharge cells between a respective first electrode, second electrode, and third electrode, comprising:
- selecting a discharge cell to be selected during an address period;
- and
- during a sustain period, alternately applying a sustain pulse to the first electrode and the second electrode so that a main discharge may occur between the first electrode and the second electrode, and biasing the third electrode by a first voltage for a predetermined time.
A method for driving a plasma display panel for forming repective discharge cells between a respective first electrode, second electrode and third electrode, comprising:
- selecting a discharge cell to be selected during an address period;
- and
- during a sustain period, alternately applying a sustain pulse to the first electrode and the second electrode so that a main discharge may occur between the first electrode and the second electrode, and floating the third electrode for a predetermined time.
