  • Patent number: 7504776
    Abstract: A plasma display panel includes a pair of substrates that are arranged opposite to each other, each having a display region to display an image and a non-display region not to display an image. Barrier ribs are located in a space between the substrates for forming a plurality of discharge cells. Phosphor layers are formed in the discharge cells. Address electrodes are formed on one of the substrates. First and second electrodes are formed on the other substrate so as to extend in a direction orthogonal to the address electrodes and are spaced apart from each other to form discharge gaps in the discharge cells. The first and second electrodes extend into the non-display region with different lengths from each other.

  • Publication number: 20080136327
    Abstract: A plasma display panel (PDP) is capable of effectively reducing noise occurring during operation of the panel by improving the construction of a dummy partition included in a partition, and reduces a rate of defects in the partition due to a uniform coating of a fluorescent paste. The PDP includes: a front glass including sustain electrodes and dielectric layers; a rear glass including address electrodes and dielectric layers; a partition between the front and rear glasses and including a main partition and a dummy partition, each having discharge spaces of respective sizes; and a fluorescent layer coated on the respective discharge spaces.

  • Publication number: 20070257614
    Abstract: Provided is a plasma display panel in which the capacitances of all discharge cells are substantially the same and the same firing voltage is applied to the discharge cells, thereby preventing an overdischarge from occurring therein and reducing the firing voltage. The plasma display panel includes a first substrate, a second substrate located to face the first substrate at a predetermined distance from the first substrate, a barrier rib structure located between the first and second substrates to define discharge cells in which a gas discharge occurs, pairs of discharge electrodes each including an X electrode and an Y electrode which extend across the discharge cells, address electrodes extending across the discharge cells to intersect the discharge electrodes in the discharge cells, and phosphor layers each being applied onto one of the discharge cells and formed of one of red, green, and blue emitting phosphors.

  • Patent number: 7271540
    Abstract: A plasma display panel (PDP) can include a front panel with a plurality of scan electrodes and a plurality of common electrodes and a rear panel with a plurality of installed barrier walls. In such a PDP, a plurality of first bus electrodes and a plurality of second bus electrodes may be formed on one surface of a front substrate of the front panel. The first bus electrodes may be formed in contact with one surface of the front substrate, and at least portions of the scan electrodes and common electrodes may be formed between the first bus electrodes and the second bus electrodes. Also, the first bus electrodes may include a conductive material that absorbs light from the other surface of the front substrate.

  • Publication number: 20070152585
    Abstract: Provided is a plasma display panel in which a dielectric layer is formed on a substrate on which electrodes are formed by a sheet lamination process. The plasma display panel includes a substrate, electrodes arranged on the substrate; and a dielectric layer disposed in a sheet form on the substrate on which the electrodes are arranged. The thickness ratio between the electrodes and the dielectric layer is in a range between 1:3.0 and 1:4.5.

  • Patent number: 7176629
    Abstract: A plasma display panel (PDP) with a novel electrode structure. An integrated bus electrode located outside of the display region is connected to many image display electrodes. This integrated bus electrode is designed to be wider and thicker in order to reduce electrical resistance and thus reduce the generation of Joule heat in the periphery regions of the PDP. This integrated bus electrode is flush with the edge of the display and is connected to a flexible printed cable which connects to drivers. Alignment marks are placed on the integrated bus electrode to locate exactly where the flexible printed cable attaches to the integrated bus electrode.
