Problems solved by technology

That is, although discharge cannot occur between the scan electrode Y4 and the sustain electrode Z4, the voltage difference between the scan electrode and the sustain electrode will cause the occurrence of misdischarge.

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail in conjunction with the accompanying drawings and examples.

[0030] image 3 It is a schematic diagram showing the structure of the plasma display panel of the dual scanning method in the example of the present invention.

[0031] refer to image 3 From the composition of the plasma display panel of the present invention, it can be seen that the image display surface is composed of a front substrate and a rear substrate 120 connected in parallel with a certain distance from the front substrate 110 .

[0032] First, on the front substrate 110, two scan electrodes and two sustain electrodes 160 and 170 form a pair in order to mutually discharge in one pixel. They are covered with structures such as a dielectric layer 180 for insulating the electrode pairs, and a protective layer 190 formed on the dielectric to protect the scan electrodes and the sustain electrodes.

[0033] In addition, in order to form a ...

Abstract

A plasma display panel is provided to prevent erroneous discharge in a divided area of address electrodes by improving a structure of the same using a dual scan method. A plurality of address electrodes are divided into two groups by a barrier rib(130). A plurality of discharge cells are discharged through the address electrodes, scan electrodes, and sustain electrodes. A rear substrate(120) includes two groups of the address electrodes which are divided by the barrier rib. A groove is formed at the barrier rib of the electrically divided part of the address electrodes. A front substrate(110) includes a convex part which is inserted into the groove formed at the barrier rib of the rear substrate. The convex part is formed with a dielectric layer(180).

Description

1. Technical field [0001] The present invention relates to a plasma display panel, more specifically, a plasma display panel with improved structure of the display panel in order to prevent misdischarge. 2. Background technology [0002] Usually, the plasma display panel is a unit unit formed by the partition wall formed between the front panel and the rear panel. In each unit, neon (Ne), helium (He) or a mixed gas of neon and helium (Ne+He) or similar main discharge gas and The filling is performed with an inert gas containing a small amount of xenon. When the high-frequency voltage is discharged, the inert gas emits vacuum ultraviolet rays (Vacuum Ultra Violet rays), which excites the phosphors formed between the partition walls to emit light, thereby forming an image. Such a thin and light plasma display panel is attracting more and more attention as a development direction of a new generation of display devices. [0003] figure 1 It is a schematic diagram showing the ...
