  • Patent number: 7714808
    Abstract: A plasma display apparatus comprises a scan electrode and a sustain electrode; a data electrode for intersecting the scan electrode and the sustain electrode; and a pulse controller for controlling to apply a pulse having an opposite phase to the scan electrode and the sustain electrode during a reset period and apply a negative sustain pulse to the scan electrode and the sustain electrode during a sustain period, wherein a distance between the scan electrode and the sustain electrode is longer than that between the sustain electrode and the data electrode. Therefore, a surface discharge mode can be used even when applying negative pulses to the sustain electrode in a reset period, and a size and cost of a plasma display apparatus can be reduced by applying a negative pulse of the same magnitude as a sustain voltage without a separate negative voltage source.

  • Publication number: 20080157670
    Abstract: A plasma display panel and a method of manufacturing the plasma display panel are disclosed. The plasma display panel includes a scan electrode, a sustain electrode, and a barrier rib formed on a glass, and an upper dielectric layer having a differential thickness formed on the glass. The upper dielectric layer covers the scan electrode and the sustain electrode. As the upper dielectric layer is far away from a discharge region portion between the scan electrode and sustain electrode, the width of the upper dielectric layer gradually increases. A distance between the scan electrode and the sustain electrode positioned within a discharge cell partitioned by the barrier rib is more than a height of the barrier rib.
