On the other hand, the partition wall 23 constituting the discharge cells of the plasma display panel is divided into a stripe shape, a well shape and a delta-type partitions, all of which have a closed partition structure.

In the discharge cells formed of the closed barrier rib structure, the scan electrodes and the sustain electrodes 10a and 10b of the upper substrate may be positioned on the non-discharge spaces in order to overcome problems such as luminance reduction in the discharge cells.

However, when the scan electrodes and the sustain electrodes 10a and 10b of the upper substrate are positioned in the non-discharge area in the closed barrier rib structure of the plasma display panel configured as described above, the scan electrodes and the sustain electrodes 10a and 10b and the lower part are disposed. It is difficult to generate opposite discharges between the address electrodes 22 of the substrate.

Accordingly, as the occurrence of the address discharge becomes difficult, not only the initial generation voltage causing the address discharge increases, but also the contamination occurs in the cell and the jitter (getter) increases. There is a problem of causing an incorrect discharge such as a flashing light.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and includes a horizontal barrier rib formed on a lower substrate of the panel in a panel in which a scan electrode and a sustain electrode of the panel are positioned on a sealed barrier rib and a non-discharge space. The purpose of the present invention is to make the discharge more easily by using a priming effect during address discharge occurring in the non-discharge space by forming a step in part or the whole.

In addition, a step may be formed in the entire horizontal partition wall corresponding to the scan electrode and the sustain electrode formed on the front substrate.

In addition, a step is formed in the horizontal partition wall corresponding to the scan electrode formed on the front substrate.

In addition, the electrodes located on the horizontal partition wall of the back substrate is characterized in that the scan electrode and the sustain electrode are arranged in order.

The plasma display panel is characterized in that the phosphor is not applied to the channel due to the step of the horizontal partition wall.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2A and 2B are cutaway views schematically showing a structure of a plasma display panel according to an embodiment of the present invention, and FIG. 3 is a cutaway view schematically showing a structure of a plasma display panel according to an embodiment of the present invention. 4 is a perspective view schematically illustrating a structure of a plasma display panel according to an embodiment of the present invention.

On the other hand, the scan electrode and the sustain electrode of the upper substrate of the plasma display panel is composed of a bus electrode and a transparent electrode.

As shown in FIG. 2A or 2B, an address electrode (not shown) for writing data on the transparent substrate 210 is positioned on the lower substrate 200 of the plasma display panel, and the address electrode (not shown) is electrically It is protected by a dielectric (230, white back), which acts as a capacitor, and comprises a horizontal partition wall (240b) is formed in part or whole on the dielectric step (H).

Here, the dielectric material 230 (white back) of the transparent substrate 210 is formed in white to prevent the discharge light is transmitted to the lower substrate, and the vacuum ultraviolet (Vacuum Ultra) generated in the discharge on the dielectric material (230, white back) Phosphor (not shown) which generates visible light by excitation of Violet, VUV) is applied.

An insulator partition wall 240 is formed to maintain a gap between the upper plate and the lower plate and to prevent interference with an adjacent cell, and the partition wall 240 is formed as a horizontal partition wall 240b and a vertical partition wall 240a. Consists of.

In the present invention forms a closed partition structure surrounded by the partitions.

The partition structure is divided into a stripe shape, a well shape, and a delta partition wall structure, all of which have a closed partition structure.

Here, the plasma display panel formed of the closed barrier rib structure generates discharge in the barrier rib, and the scan electrode 100a of the panel upper substrate generates an opposite discharge with the address electrode (not shown) of the lower substrate. After the discharge cell is selected by the opposite discharge, the discharge is maintained by the surface discharge between the scan electrode 100a and the sustain electrode 100b of the upper substrate, thereby emitting visible light.

In addition, the plasma display panel has a closed barrier rib structure and a scan electrode 100 a or a sustain electrode 100 b positioned on the barrier rib which is an ineffective discharge region.

By forming a step H on part or all of the horizontal partition wall 240b among the partition walls of the panel, an address discharge is generated between the scan electrode 100a of the upper panel of the panel and the address electrode (not shown) of the lower substrate. The address discharge of the discharge space can be more easily generated by using a priming effect caused by a discharge previously generated in the space between the scan electrode 10a positioned in the non-discharge space and the address electrode (not shown) of the lower substrate. It was made.

Here, the priming effect means that in the discharge space and the non-discharge space of the plasma display, the discharge is formed on the discharge space by an address discharge generated in advance in the discharge space formed in the non-discharge space. .

 As shown in FIG. 3, the plasma display panel according to an exemplary embodiment of the present invention has only the horizontal partition wall 240b on the side corresponding to the scan electrode Y of the upper substrate which causes the discharge electrode to face the address electrode of the lower substrate. It is a structure which forms step H.

Here, the horizontal partition wall 240b is formed in parallel with the scan electrode 100a of the upper substrate of the panel, by forming a step H in the direction of the scan electrode 100a on the horizontal partition wall 240b. Therefore, the discharge phenomenon that occurs in the non-discharge space affects the discharge space through the step H.

That is, a priming effect is generated which transmits the discharge effect on the non-discharge space into the discharge space.

In addition, as shown in FIG. 4, the plasma display panel according to the present invention has a closed partition structure, and the scan electrodes and the sustain electrodes 100a and 100b of the upper substrate are positioned in the non-discharge space of the panel, and the lower substrate is disposed on the lower substrate. A step H is formed on the horizontal partition wall 240b formed in parallel with the scan electrodes and the sustain electrodes 100a and 100b, and a groove c is formed below the horizontal partition wall 240b of the non-discharge space. .

Here, a small amount generated during address discharge of the panel on the non-discharge space by placing scan electrodes and sustain electrodes 100a and 100b on the non-discharge space and forming a step H on the horizontal partition wall 240b. The priming effect affects the discharge space through the step H formed on the horizontal partition wall 240a.

In addition, by forming a groove (c) under the horizontal partition wall 240b of the lower substrate, the discharge during the address discharge generated between the scan electrode (100a) of the upper substrate and the address electrode (not shown) of the lower substrate It is to have the discharge effect into space.

Here, the groove c is formed in parallel with the scan electrode 100a of the upper substrate and the address electrode (not shown) of the lower substrate, thereby forming a space for discharging in advance.

In addition, the step H of the horizontal partition wall 240b formed on the lower substrate may be formed in parallel with the scan electrodes and sustain electrodes 100a and 100b on the upper substrate, and the scan electrodes 100a on the upper substrate. Only parallel may be formed.

In addition, when the scan electrode 100a and the scan electrode 100a are formed, and then the sustain electrode 100b and the sustain electrode 100b are arranged in sequence, the electrode structure of the upper substrate of the panel discharges the panel. According to whether or not the address of the previous cell is discharged in the space, there is a structure in which the characteristics of the discharge voltage Va and the jitter can be greatly different.

Here, when the electrode structure is formed as described above, if the previous cell discharges, it also has a great influence on the discharge of the adjacent discharge cells. Accordingly, the discharge voltage Va of the adjacent cells changes and impurities generated in the discharge cells of the previous cells. It is undesirable to increase the amount of jitter that must be applied to the discharge cell septum of the panel for the purpose of adsorbing gas passing to adjacent cells.

In addition, the getter material may be applied to the groove (c) formed on the partition wall of the lower substrate or the entire upper part of the partition wall, wherein the getter material is a metal such as zirconium, aluminum, vanadium, titanium, or the like. It is made of a material, and the adsorption to remove the impurity gas generated during the discharge of the plasma display panel.

Accordingly, in the electrode structure of the panel, the scan electrode 100a and the sustain electrode 100b are formed and then the scan electrode 100a and the sustain electrode 100b are formed in order to stabilize the discharge voltage Va and the jitter ( It would be desirable to avoid changing the properties of the getter).

Here, when the impurity gases enter the adjacent discharge cells, only the desired cells may be turned on when the adjacent electrodes are formed in the order of the scan electrode 100a and the sustain electrode 100b so that the two cells are not turned on.

In addition, phosphors should not be applied to the grooves c below the barrier rib formed on the lower substrate.

This may prevent the color from appearing through the black matrix on the non-discharge space of the panel when the phosphor is not applied in the manufacturing process of the plasma display panel, but the half capacitance value is reduced. Can be reduced.

Therefore, the scan electrodes and the sustain electrodes 100a and 100b of the upper substrate are formed on the horizontal partition wall 240b forming the non-discharge space, and a part or all of the steps H are formed to form the discharge space. When the address discharge is generated in the discharge, the discharge is formed in advance in the non-discharge space, so that the address discharge in the discharge region can be more easily generated.

As described above, the plasma display panel according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and may be applied within a range in which technical thoughts are protected.

The plasma display panel according to the present invention configured as described above forms a stepped partition in part or all on the horizontal partition of the panel which forms the scan electrode and the sustain electrode in the sealed barrier rib and the non-discharge space. The address discharge of the discharge space of the panel can be more easily performed by using a priming effect that affects the discharge space of the discharge electrode between the scan electrode and the sustain electrode located at the lower substrate and the lower substrate. .
