Embodiment Construction

[0036] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] 4 is a plan view of a discharge cell having a grid-shaped electrode configuration according to the present invention. As shown in Figure 4, scan electrodes 420 and sustain electrodes 440 are formed on the front panel (not shown) of the plasma display according to the present invention, and the address electrodes (shown in Fig. The partition wall 430 that divides the discharge cell 460 using the positive column region during plasma discharge is formed on the rear panel (not shown) formed in the figure.

[0038] At this time, the scan electrodes 420 and the sustain electrodes 440 are not formed of transparent electrodes, but are only formed of bus electrodes. This design change of using bus electrodes with a smaller area in the discharge space to replace the transparent electrodes can replace the transparent electrodes. The effect of forming scan e...

Abstract

The invention relates to a plasma display, in particular to a plasma display that improves the electrode structure with a positive column area during the electric discharge of plasma, which comprises the following parts: a front faceplate is formed by a scanning electrode and a maintenance electrode; a rear faceplate is formed on an addressing electrode that is arranged alternatively on the scanning electrode and the maintenance electrode; the rear faceplate is taken as a spacing wall that forms a discharge unit by utilizing the positive column area during the electric discharge of the plasma. The invention is characterized in that: the scanning electrode and the maintenance electrode are composed of different bus electrodes; the bus electrode is arranged along the spacing wall and leads to an upper discharge and ignition section and a lower discharge and ignition section in preliminary discharge; generate the preliminary discharge by utilizing the upper discharge and ignition section and the lower discharge and ignition section, so as to generate light in the positive column area in the discharge unit and then the light will diffuse to an upper discharge and diffusion section and a lower discharge and diffusion section in all discharge units.

Description

technical field [0001] The invention relates to a plasma display, in particular to a plasma display which utilizes a positive column region (Positive Column) region to improve electrode structure during plasma discharge. Background technique [0002] In general, a plasma display (Plasma Display Panel: hereinafter referred to as PDP) is a device in which a partition wall formed between a front panel and a rear panel made of soda lime glass forms a unit cell, and in each cell, helium -When inert gases such as xenon (He-Xe) and helium-neon (He-Ne) are discharged under high-frequency voltage, the vacuum ultraviolet rays generated can make the phosphors between the partition walls emit light, thereby displaying images. [0003] FIG. 1 is a schematic diagram of a PDP structure according to the prior art. As shown in the figure, the PDP 100 is assembled in parallel at a certain distance from a display front panel 10 for displaying images and a rear panel 20 constituting a back pan...
