ABSTRACT:
A plasma display panel and a method and apparatus for driving the same that are capable of preventing miss-writing and improving discharge and light-emission efficiencies. In the panel, an upper substrate and a lower substrate are opposed to each other with having a plurality of discharge cells therebetween. A first upper electrode group includes at least one electrode having a desired width and is formed on the upper substrate. A second upper electrode group includes at least one electrode having a different width from the first upper electrode group and is formed on the upper substrate in such a manner to be adjacent to the first upper electrode group. A data electrode is provided on the lower substrate in such a manner to be perpendicular the first and second upper electrode group. In the method and apparatus, a short-path discharge occurs between two electrodes spaced at a small distance from each other, of electrodes included in the first and second upper electrode groups. A long-path discharge occurs between the two electrodes spaced at a larger distance than said distance between the electrodes causing the short-path discharge of said electrodes included in the first and second upper electrode groups.
