A plasma display and driving method thereof. A median electrode is formed between X and Y electrodes for receiving sustain pulse voltages, and a reset waveform and a scan pulse voltage are applied to the median electrode. A short gap discharge is performed between the X electrode and the median electrode during the initial interval of a sustain interval, and a long gap discharge is performed between the X and Y electrodes during the normal sustain interval to thus perform a stable discharge. The X and Y electrode drivers are realized through comparable circuits since the waveforms applied to the X and Y electrodes are substantially symmetric.

摘要:
A plasma display panel including a first substrate and a second substrate, a plurality of address electrodes, a plurality of display electrodes, and a barrier rib. The address electrodes and the display electrodes are formed between the first and second substrates. The barrier rib is disposed in a space between the first and second substrates and defines a plurality of discharge cells. A gas exhaust passageway is formed between discharge cells neighboring each other along a diagonal direction. The passageways and the discharge cells cooperatively form a gas exhaust route that repeats breaking away by a predetermined pitch, and returning, thereby zigzagging along an elongation direction of the address electrode.
