  • Publication number: 20090211776
    Abstract: A position adjustment of substrates is facilitated by using a sealing/bonding material consisting of a translucent colored glass material. A plasma display panel has a frontside substrate and a backside substrate facing to each other, on which electrodes are formed respectively, and a sealing/bonding material placed on a sealing/bonding area on a peripheral portion of one of the substrates, by which the two substrates are sealed and bonded to each other. The sealing/bonding material is made from a translucent colored material.

  • Patent number: 6054970
    Abstract: A method for driving an AC-driven plasma display panel (PDP) having a three-electrode surface discharge structure constructed to have a first electrode and a second electrode both extending in a direction of a row line of elements arranged in matrix and a third electrode extending in a direction of a column line of the elements, the method including the step of applying, upon displaying images in time sequence, erase voltage pulses of different polarities for erasure to the second electrode and the third electrode so that an effective voltage exceeds an opposition discharge start voltage only in the case where a wall voltage of a predetermined value or higher is superposed on the voltage pulses, during a period from the end of sustaining the light-emission discharge for display for an image to the beginning of addressing for a next image.
