    Abstract: A plasma display panel includes a first substrate, on which discharge sustain electrodes are formed, and an opposing second substrate, on which address electrodes are aligned in a first direction. Barrier ribs between the substrates define a plurality of discharge cells within which phosphor layers are formed. The display electrodes have bus electrodes, forming a corresponding pair within each of the discharge cells, and extension electrodes, extending from the bus electrodes into each of the discharge cells to form an opposing pair. A pair of the display electrodes corresponding to each of the discharge cells forms a first gap and a second gap having different distances from each other between the opposing extension electrodes, and forms a third gap between the bus electrodes. The second gap is longer than the first gap, and the third gap is longer than the second gap.

  • Patent number: 7501998
    Abstract: A plasma display panel (PDP) that has a T-shaped electronic structure or an electrode structure with adjacent parts of the scan electrode and the sustain electrode being broad, and parts coupled to the bus electrodes being narrow in a like manner to the T-shaped electrode structure is provided. The PDP has various discharge modes according to magnitudes of sustain discharge voltages. A frame is divided into a plurality of subfields with respective weights and is driven in the PDP. The subfields with low weights use low sustain discharge voltages to perform a discharge with a small quantity of emitting light, and the subfields with high weights use high sustain discharge voltages to perform a discharge with a big quantity of emitting light, thereby increasing representation performance of low gray scales.

  • Patent number: 7375466
    Abstract: A plasma display panel where the address electrodes are designed to have perforated portions in the vicinity of display electrodes to prevent the build up of unwanted wall charges in the vicinity of the display electrodes to thus prevent mis-discharge in the plasma display panel. The perforations can be quadrilateral in shape, and can be made to different sizes depending on the color of the phosphor in the vicinity of the perforation. As a result, drive voltage margin quality between the different colors can be improved to produce a more reliable display.
