Abstract
An alternating current type plasma display panel with electrodes of asymmetrical construction and a method for driving the same. A first pulse is applied to the first electrode. A second pulse is applied to the second electrode, the second pulse having a width and a phase different from those of the first pulse. The pulse widths are adjusted according to a size of the electrodes to make an amount of a wall charge in two electrodes substantially uniform, thereby making the intensity and an amount of the light uniform.

A plasma display panel comprising:
- a first substrate and a second substrate that face each other;
- a plurality of first electrodes between the first substrate and the second substrate, and coupled to each other in a first direction by a first electrode line, with discharge holes at central regions of the first electrodes;
- a dielectric enclosing the first electrode and the first electrode line and coupling the plurality of first electrodes to each other in a second direction;
- a plurality of second electrodes on the second substrate corresponding to the discharge holes, and coupled to each other in the second direction by a second electrode line;
- and
- a fluorescent layer on the first substrate, wherein the fluorescent layer is exposed through the discharge holes.
A method for driving an alternating current type plasma display panel including a first electrode and a second electrode of an asymmetrical construction, comprising:
- applying a first pulse to the first electrode;
- and
- applying a second pulse to the second electrode, the second pulse having a width and a phase different from those of the first pulse.
A plasma display panel prepared by a process comprising:
