Embodiment Construction

[0024] 1 is a partial sectional view of a plasma display panel (PDP) according to a first embodiment of the present invention. As shown in the figure, a first substrate 20 and a second substrate 22 define the exterior of the PDP, the two substrates being arranged substantially in parallel with a predetermined gap therebetween.

[0025] On the surface of the first substrate 20 opposite to the second substrate 22 are formed a plurality of address electrodes 26 arranged in parallel in stripes and a transparent insulating layer 24 covering the address electrodes 26 . On the surface of the second substrate 22 opposite to the first substrate 20, a plurality of discharge sustain electrodes 30 arranged in parallel in stripes are formed and are perpendicular to the address electrodes 26 formed on the first substrate 20, covering the discharge sustain electrodes. The transparent insulating layer 28 of the electrode 30, and a transparent protective layer (not shown) made of a material su...

Abstract

A plasma display panel having a helicon plasma source. First and second substrates are mounted substantially in parallel with a predetermined gap therebetween. A plurality of address electrodes are formed on a surface of the first substrate opposing the second substrate. A first dielectric layer is formed covering the address electrodes. A plurality of barrier ribs are formed on the first dielectric layer at a predetermined height, the barrier ribs defining discharge cells. A phosphor layer is formed in the discharge cells. A plurality of discharge sustain electrodes are formed on a surface of the second substrate opposing the first substrate. A second dielectric layer is formed on the second substrate covering the discharge sustain electrodes. Discharge gas injected into the discharge cells. Antenna and magnet assemblies are provided to increase a plasma density in the discharge cells.

Description

technical field [0001] The invention relates to a plasma display panel, in particular to a plasma display panel using a helicon wave plasma source. Background technique [0002] A plasma display panel (PDP) is a display device that displays images using the emission phenomenon that occurs in discharge cells. Among the many different PDP structure types that have been developed, only AC PDPs have been commercially produced, in which the surface discharge structure is more common than the pillar discharge structure. In an AC PDP of surface discharge structure, one AC voltage is used to initiate a discharge action between two electrodes on opposite substrates, and another AC voltage is used to maintain a discharge between two electrodes on the same substrate. Such an AC PDP will be described in detail with reference to FIG. 7. FIG. [0003] Fig. 7 shows a partial sectional view of a conventional AC PDP. As shown in the figure, the conventional AC PDP includes an upper substr...
