Plasma display apparatus, plasma display panel, and driving device and method thereof

A plasma display panel having a scan electrode, a sustain electrode and an address electrode for applying a predetermined voltage by constituting one frame of a combination of a plurality of subfields having the different number times of emission and dividing each subfield into a reset period, an address period, and a sustain period,

• wherein a scan reference voltage, which is greater than the lowest voltage of the reset period and is less than or the same as a reference voltage of the sustain period, and a scan pulse voltage, which is less than the scan reference voltage, are supplied to the scan electrode during the address period.

A driving device of a plasma display panel for displaying an image by applying a predetermined voltage to at least one electrode, by constituting one frame of a combination of a plurality of subfields having the different number times of emission and dividing each subfield into a reset period for initialization, an address period for selecting a cell, and a sustain period for sustaining discharge of the selected cell, the driving device comprising:

• a scan driver for supplying a scan reference voltage, which is greater than the lowest voltage of the reset period and is less than or the same as a reference voltage of the sustain period, and a scan pulse voltage, which is less than the scan reference voltage, to the scan electrode during the address period.

A driving method of a plasma display panel for displaying an image by applying a predetermined voltage to at least one electrode, by constituting one frame of a combination of a plurality of subfields having the different number times of emission and dividing each subfield into a reset period for initialization, an address period for selecting a cell, and a sustain period for sustaining discharge of the selected cell, the method comprising the step of:

• supplying a scan reference voltage, is greater than the lowest voltage of the reset period and is less or the same as a reference voltage of the sustain period, and a scan pulse voltage, which is less than the scan reference voltage, to the scan electrode during the address period.
