Abstract
A plasma display panel and a driving method thereof that is capable of improving a discharge efficiency as well as preventing a crosstalk. In the panel, an address electrode is included in each discharge cell making a unit pixel of the plasma display panel. A plurality of second sustain electrodes are positioned at each periphery of the discharge cell in a direction crossing the address electrode to receive a second sustaining pulse. At least one of first sustain electrode is positioned at the center of the discharge cell in a direction crossing the address electrode to receive a first sustaining pulse applied alternately with respect to the second sustaining pulse.
Claims17
A plasma display panel, comprising:
- an address electrode included in each discharge cell making a unit pixel of the plasma display panel;
- a plurality of second sustain electrodes positioned at each periphery of the discharge cell in a direction crossing the address electrode to receive a second sustaining pulse;
- and
- at least one of first sustain electrodes positioned at the center of the discharge cell in a direction crossing the address electrode to receive a first sustaining pulse applied alternately with respect to the second sustaining pulse.
A method of driving a plasma display panel including a plurality of second sustain electrodes positioned at each periphery of a discharge cell, an address electrode arranged in a direction crossing the second sustain electrodes, and at least one of first sustain electrode formed in parallel to the second sustain electrodes between the second sustain electrodes, said method comprising the steps of:
- applying a reset pulse to at least one electrode of the first sustain electrode and the second sustain electrodes so as to initialize the discharge cell;
- applying a scanning pulse to the first sustain electrode so as to select the discharge cells to be turned on;
- applying a data pulse synchronized with the scanning pulse to the address electrode;
- and
- alternately applying the sustaining pulse to the first and second sustain electrodes so as to discharge the discharge cells to be turned on.

A plasma display panel, comprising:
- a sustain electrode pair provided at each edge of an upper substrate;
- first and second trigger electrodes formed in parallel to the sustain electrode pair between the sustain electrode pair;
- a dielectric layer coated on the entire surface of the upper substrate in such a manner to cover the sustain electrode pair and the first and second trigger electrodes;
- and
- at least two floating electrodes formed in parallel to the sustain electrode pair at the rear side of the dielectric layer.
