  • Patent number: 7649318
    Abstract: A plasma display panel capable of increasing a luminous efficiency while decreasing discharge firing voltage while easily generating an address discharge by generating a sustain discharge as facing discharge. The discharge sustain electrodes are on barrier ribs between the two substrates. One of the sustain discharge electrodes extends between discharge cells and the other extends through discharge cells dividing discharge cells into two portions. Each discharge sustain electrode is surrounded by a dielectric material and also a non-transparent MgO protective layer. These electrodes are formed to be tall and narrow to allow for superior facing discharge potential.

  • Patent number: 7554267
    Abstract: A PDP having an opposing electrode structure including first and second substrates facing each other. A space between the first and second substrates is divided into discharge cells. Address electrodes extend in a first direction between the first and second substrates, and first and second electrodes extend in a second direction intersecting the first direction while being spaced apart from the address electrodes. At least one of the address electrodes or the first and second electrodes has a protruding portion that protrudes toward the center of each discharge cell. The protruding portions help reduce the discharge gap which in turn reduces the discharge firing voltage. Expansion portions formed as parts of the first and second electrodes increase the discharge gap used by the sustain discharge and lead to an improved luminescence efficiency.
