Abstract: In a plasma display and a method of driving a plasma display, a discharge is generated in a sustain period since a first voltage is supplied to a scan electrode and a second voltage lower than the first voltage is supplied to a sustain electrode. Accordingly, a discharge current flows since wall charges are formed on the scan and sustain electrodes as a result of the discharge. When the discharge current flows, a third voltage lower than the first voltage and higher than the second voltage is supplied to the sustain electrode while the first voltage is supplied to the scan electrode. In addition, when another discharge current flows since a sustain discharge is generated by supplying the first voltage to the sustain electrode and suypplying the second voltage to the scan electrode, the third voltage is supplied to the scan electrode while the first voltage is supplied to the sustain electrode.

Abstract: In a plasma display device, an M electrode is provided between the X and Y electrodes. When an X or Y electrode driver applies a sustain pulse voltage of Vs/2 during a sustain period, a third power source also applies voltage Vs/2 to a node of the M electrode driver. The node of the M electrode driver is alternately connected to the drivers for the X and Y electrodes, thus increasing the total sustain pulse voltage differences between those electrodes to Vs. Therefore, the voltage of the power sources used to apply the sustain pulses can be reduced. Additionally, the M electrode applies the reset waveforms in the reset period, allowing the X and Y electrode driver circuits to be nearly identical. Therefore, a uniform sustain waveform is applied, and poor discharge in the sustain period is reduced.

Abstract: A plasma display device and a driving method thereof. A scan electrode driver (or a sustain electrode driver) uses a power source for supplying the voltage Vs-Va to increase the initial voltage to the voltage Vs-Va and uses an address voltage output by an address electrode driver to increase the voltage Vs-Va to the voltage Vs to thus apply a sustain discharge pulse during a sustain period. Therefore, the voltage used by a driver for applying the sustain discharge pulse is reduced by using a voltage output by the address driver to apply the sustain pulse voltage.

Abstract: In a plasma display device and driving method thereof, middle electrodes are formed between X electrodes for receiving a sustain pulse voltage and Y electrodes. A reset waveform and a scan pulse voltage are applied to the middle electrodes. A short-gap discharge is performed between the X electrode and the middle electrode in the earlier stage of a sustain discharge period, and a long-gap discharge is normally performed between the X electrode and the Y electrode after the earlier stage of the sustain discharge period, thereby performing stable discharge. Further, the number of switches of the M electrode driver may be reduced by floating the M electrode and applying a rising ramp waveform to the Y electrode in the reset period, thereby increasing the voltage at the M electrode.
