Abstract:
A plasma display panel in which initialization operation and address operation characteristics are stabilized. Priming discharge takes place between an auxiliary electrode (17) connected with a scanning electrode (6) formed on a front substrate (1) and a priming electrode (14) formed on a back substrate (2). Since a material layer (5) of at least any one of an oxide of alkaline metal, an oxide of alkaline earth metal, or a fluoride is provided in a region corresponding to the priming discharge space (30) (gap part 13) of the back substrate (2), margin of priming discharge is widened, supply of priming particles to the discharge cell is stabilized, and address characteristics are stabilized by reducing discharge lag at the time of addressing.
Abstract:
A pair of display electrodes of a gas discharge panel forms narrowest gaps between inner projections provided on a first bus line and an opposite bus line or between the inner projections provided on the first bus line and inner projections provided on the other bus line. Since a discharge is started by the charge concentrated in the narrowest gaps, the firing potential becomes lower than the conventional. The discharge expands gradually to outer projections such that a sustained discharge (surface discharge) can be secured over a wide area. Therefore, a desired scale of discharge improving is achieved while increasing the luminous efficiency.

Abstract:
An intermediate electrode is formed in a space between an X display electrode and a Y display electrode parallel thereto. A negative voltage is applied to the Y display electrode to use the Y display electrode as a cathode. A charge is stored between the Y display electrode and an intermediate electrode to create an electric field. Upon the increase of the intensity of the electric field to a sufficiently high level, an instant discharge occurs between the Y display electrode and the X display electrode and intense ultraviolet rays are produced. The fluorescent layer excited by the ultraviolet rays emits visible light. Only a narrow pulse current flows through the X display electrode and the Y display electrode, so that power consumption can be suppressed at high emission efficiency.
Abstract:
The present invention relates to a plasma display device. The plasma display device includes a plasma display panel including an upper substrate having a scan electrode and a sustain electrode, and a lower substrate having a barrier rib for dividing discharge cells, and a driver disposed at one side of the plasma display panel and applying a driving signal to the scan electrode and the sustain electrode. At least one of the scan electrode and the sustain electrode includes a first electrode unit extending on the barrier rib from the driver to a non display area disposed at the other side of the plasma display panel, and a second electrode unit connected to the first electrode unit and extending from the non display area to the driver on discharge cells that are adjacent to an upper side and a lower side of the barrier rib. Current flows in the scan electrode and the sustain electrode in opposite directions on the discharge cells. Therefore, it is possible to reduce brightness deviation between discharge cells adjacent to the driver and another discharge cells adjacent to the non display area.
