  • Patent number: 7812537
    Abstract: A plasma display panel is disclosed. The plasma display panel includes a first substrate, a second substrate, a first electrode and a second electrode formed on the first substrate, a center electrode and a third electrode. The center electrode includes a plurality of division electrodes for forming a plurality of discharge gaps between the first electrode and the center electrode and between the second electrode and the center electrode. The third electrode is formed on the second substrate to intersect the center electrode.

  • Publication number: 20070024536
    Abstract: A method for driving a plasma display panel are disclosed to prevent an erroneous discharge according to an incomplete reset or according to a high speed driving and to improve the contrast. By further providing a certain bias voltage before an addressing voltage is provided, wall charges can be effectively formed. By preventing a dark discharge between X and Y electrodes, a level of the wall charges can be properly controlled to reduce a time needed for inducing an opposed discharge under addressing to improve luminance. By properly forming wall charges, an erroneous discharge can be prevented, and by providing a bias voltage for preventing the dark discharge, contrast characteristics can be improved.
