  • Patent number: 7298087
    Abstract: A plasma display panel is provided which evenly deposits a phosphorus layer by forming a buffer layer before forming the phosphorus layer within a discharge cell of a rear surface substrate. The plasma display panel includes a front substrate on which are formed common sustain electrode and scan sustain electrodes and through which light is emitted and a rear substrate on which discharge cells are formed by barrier ribs and address electrodes. The rear substrate may be bonded to the front substrate by frit glass.

  • Patent number: 7034443
    Abstract: A plasma display panel configuration helps to prevent unwanted discharge generation in cells adjacent to excited discharge cells and to improve picture quality of the plasma display panel. An exemplary embodiment of the present invention includes barrier ribs for partitioning off discharge cells, wherein edge parts of the cross sectional shape of the barrier ribs are lower than central parts of the cross sectional shape of the barrier ribs and can have a number of distinctive shapes.

  • Patent number: 6972739
    Abstract: A method of driving a plasma display panel that is adaptive for improving a picture quality. In the method, a scanning pulse is applied to first electrodes so as to select a discharge cell in an address period. A data pulse synchronized with the scanning pulse is applied to address electrodes arranged to cross the first electrodes. A reset pulse is applied to the first electrodes in the reset period, and a pulse width of the reset pulse is set differently depending upon an application sequence of the scanning pulse.
