Description

Electrode Structure of Color Plasma Display Panel

The present invention relates to a color plasma display panel, and more particularly to a sustain electrode of a color plasma display panel.

In general, a color plasma display panel has a scan electrode (Y electrode), a sustain electrode (Z electrode), an upper substrate on which a dielectric layer is formed, and a lower substrate on which a partition, a phosphor, and an address electrode (X electrode) are formed. Display device.

The panel having the above-described structure excites phosphors by ultraviolet rays emitted during discharge between electrodes to generate visible light. There are three kinds of discharges. That is, the write discharge for the first discharge, the sustain discharge which holds the discharge of the lighted discharge cell, and the erase discharge which stops the sustain of the sustained discharge cell. The write discharge is also called an address discharge, and refers to a discharge between the scan electrode of the upper substrate and the address electrode of the lower substrate.

This discharge causes wall charges that were not previously inside the discharge cell to form in the dielectric layers near the scan electrodes and the sustain electrodes. This wall charge serves to maintain the discharge along with the sustain pulse between the scan electrode and the sustain electrode.

Referring to FIG. 1, a top electrode structure of a general color plasma display panel includes a metal electrode 11 and a transparent electrode as a sustain electrode on a partition wall 10 formed to prevent crosstalk between adjacent cells. Indium-Tin Oxide (ITO) 12 is formed.

The operation of the electrode of the color plasma display panel formed as described above is as follows.

First, when a driving voltage is applied to the sustain electrode composed of the metal electrode 11 and the transparent electrode 12, wall charges are generated.

Subsequently, discharge occurs in the discharge region due to the voltage difference of the wall charges.

The discharge causes surface discharge in the discharge region on the surface of the dielectric layer and the dielectric protective layer to generate ultraviolet rays.

Color display is performed as the fluorescent material of the phosphor layer is excited by the generated ultraviolet rays.

Due to the structure of the sustain electrode of the color plasma display panel configured as described above, a wide discharge area cannot be secured, and the sustain electrode partially blocks visible light, thereby lowering the transmittance of visible light, thereby making it difficult to realize high brightness.

The present invention has been made to solve the problems according to the prior art, an object of the present invention is to provide a sustain electrode of a color plasma display panel to secure a wide discharge area and to increase the transmittance of visible light.

A color plasma display panel having a high resolution including a first line electrode and a second line electrode formed parallel to the upper substrate at regular intervals and column electrodes alternately formed on the first line electrode and the second line electrode. To produce.

According to another aspect of the present invention, a color plasma display panel having an upper substrate having a sustain electrode formed thereon and a plurality of partition walls formed in one direction and preventing crosstalk between adjacent cells, wherein the plurality of partition walls are spaced correspondingly on the plurality of partition walls. The present invention provides a high-resolution color plasma display panel in which column electrodes are successively formed on a first line electrode and a second line electrode formed in parallel with an upper substrate, and a line electrode on one side of the sustain electrode to correspond to the partition wall.

Hereinafter, exemplary embodiments of the electrode structure of the color plasma display panel according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a layout showing an electrode structure of a color plasma display panel according to the present invention.

Referring to FIG. 2, the electrode structure of the color plasma display panel according to the present invention includes a first line electrode 21 and a second line electrode formed parallel to the upper substrate at regular intervals to correspond to the plurality of partition walls 20. And the column electrodes 23 alternately formed on the first and second wire electrodes 21 and 22.

The first line electrode 21, the second line electrode 22, and the column electrode 23 are formed of metal electrodes. Here, the line electrode and the column electrode are sustain electrodes, and the sustain electrodes use only metal electrodes and are positioned to correspond to the upper surface of the barrier rib formed on the lower substrate.

The operation of the upper electrode of the color plasma display panel according to the present invention formed as described above is as follows.

When a driving voltage is applied to the first line electrode 21 and the second line electrode 22, the first discharge occurs by triggering at the peak of the alternating column electrodes 23, and the discharge is generated in the discharge region in the cell. It happens magnified.

Since the discharge phenomenon crosses the diagonal direction alternately with each other, since the discharge occurs at the maximum effective distance within the range in which the discharge can occur, the amount of plasma particles generated during the discharge increases.

As the amount of the plasma particles increases, the ultraviolet rays rapidly increase and the generation of visible rays by the ultraviolet rays increases, thereby increasing the luminance.

The discharge causes discharge in the discharge region on the surface of the dielectric protective layer to generate ultraviolet rays. By the generated ultraviolet rays, red, green, and blue phosphors of the phosphor layer formed on the lower substrate are excited to return to the ground state to generate visible light.

3 is a layout showing another embodiment of the sustain electrode of the color plasma display panel according to the present invention.

Referring to FIG. 3, the sustain electrode includes a first line electrode 21 and a second line electrode 22 formed parallel to the upper substrate at regular intervals on the plurality of partition walls 20, and the partition walls ( The column electrode 23 is continuously formed on one side line electrode 21 of the sustain electrode to correspond to 20). The sustain electrode uses only a metal electrode and is positioned to correspond to an upper surface of the barrier rib formed on the lower substrate.

The panel configured as described above serves as a discharge trigger at the peak of the column electrode 23, causing the other side to discharge with the line electrode, and the initial discharge is diffused into the discharge region on the surface of the dielectric protective layer. The column electrode 23 is continuously formed on the upper substrate so as to correspond to the partition wall 20 formed on the lower substrate, and is formed wider than the width of the partition wall 20.

Therefore, since the width of the column electrode 23 is greater than the width of the upper surface of the partition wall 20 and protrudes into the adjacent cell after the sealing process of the upper substrate and the lower substrate, the protruding portion serves as a trigger for the initial discharge and facilitates the discharge. do.

Since the sustain electrode uses only a metal electrode and is positioned to correspond to an upper surface of the barrier rib formed on the lower substrate, the transmittance of visible light generated on the phosphor layer of the lower substrate can be maximized. In addition, the present invention can compensate for the visible light transmittance of about 10% in the conventional ITO electrode.

Therefore, the panel of the present invention has a wide discharge area and increases the transmittance of visible light of the upper substrate, thereby making it possible to manufacture a color plasma display panel of high quality and high reliability.

The electrode structure of the color plasma display panel according to the present invention is formed by alternatingly forming column electrodes on the first line electrode and the second line electrode, which are formed at regular intervals on a plurality of partition walls, thereby securing a wide discharge area. The color plasma display panel can be manufactured.

In addition, since the sustain electrode uses a metal electrode instead of an indium-tin oxide (ITO), the manufacturing process of the panel is simple.
