Description

Aging Apparatus of a PDP Panel {AIGING APPARATUS OF PDP PANEL}

The present invention relates to an aging apparatus for a PDP panel, and more particularly, to buses the upper glass of the PDP panel that is already shorted on the pattern when power is supplied to the entire electrode pattern to aging the PDP panel sealed with the upper glass and the lower glass. Aging device of PDP panel that connects the electrode through short bar shorter than bus electrode to secure the moving space of other short bar and to supply power for aging test to both bus electrode and address electrode even for PDP panels of various sizes It is about.

Currently used image display devices include a cathode ray tube (CRT), a flat panel display (LCD), a plasma display panel (PDP), and the like.

Among the image display devices, the cathode ray tube has superior performance to other devices in terms of image quality and brightness. However, there are disadvantages in that they are not suitable for applications requiring a large screen because they are bulky and heavy.

On the other hand, the flat panel display device has an advantage that the volume and weight is very small compared to the cathode ray tube, and its use is gradually increasing, and research on the display device as a next generation display device is being actively conducted.

In general, PDP (Plasma Display Panel) is neon by putting a gas such as Ne + Ar, Ne + Xe between the upper glass and the lower glass and the glass sealed by the partition between them It refers to an electronic display device that emits light to use as display light.

Accordingly, the plasma display displays various characters or patterns by forming a discharge intersection between the vertical pattern electrodes and the horizontal pattern electrodes of the upper glass and the lower glass that face each other by discharging cells.

In addition, PDP has been widely used for FA (factory automation) because it is possible to display large size with clear light, but now it is widely used for OA (office automation) such as personal computer with small size, light weight and high performance of display device. As display panel is not only high display quality but also fast response speed, demand is increasing rapidly as it is adopted as wall-mounted TV.

Since the PDP is configured to emit light by discharge due to plasma generation at the intersection of the electrode patterns formed on the upper glass and the lower glass, the yield of the finished product is determined according to the electrical characteristics of the electrode patterns formed on the upper glass and the lower glass.

FIG. 1 is a view illustrating electrode patterns formed on a top glass and a bottom glass of a general PDP, (A) is an electrode pattern formed on a top glass, (B) is an electrode pattern formed on a bottom glass, and FIG. 2 is a general PDP panel. This is a conceptual diagram for explaining the cell structure.

As shown here, the electrode patterns 12 and 22 are formed on the upper glass 10 and the lower glass 20, and then the bus electrodes 14 are formed on the transparent electrode that is the electrode pattern 12 of the upper glass 10. The first dielectric layer 16 and the protective film MgO layer 18 are formed. Then, after forming the second dielectric layer 24 on the address electrode 22 of the lower plate glass 20, a partition wall 26 for dividing cells is formed, and a phosphor 28 and a seal in the partition wall 26 are formed. ) The material 30 is applied.

After forming the upper plate 10 and the lower plate 20 of the PDP as described above, the bus electrodes 14 and the address electrodes 22 are bonded to each other perpendicularly to each other, and then exhaust and gas are sealed.

In addition, aging or burn-in that operates by applying power to all the upper and lower patterns of the PDP module to remove the gas generated by applying plasma to all cells after exhaust sealing. By performing the test, not only the gas generated due to the abnormality of the electrode pattern and the generation of plasma but also the problem that may occur during operation is eliminated.

In the case of using such a PDP panel as a display device, when a corresponding amount of plasma is formed by applying power to a bus electrode of the upper plate and selecting a corresponding cell through the address electrode, the plasma generated in the selected cell is activated to emit phosphors. It can be used as a display device.

3 is a diagram illustrating a connection state of a short bar in an aging apparatus of a general PDP panel, (A) shows a state in which a short bar is connected to a PDP panel, and (B) a state in which a short bar is not connected to a PDP panel. The figure which shows.

As shown in (a), the first to second short bars 51 and 52 for simultaneously supplying power to all the bus electrodes 14 formed on the top glass 10 of the PDP panel 40, and the PDP. The third to fourth short bars 53 and 54 for simultaneously applying power to all the address electrodes 22 formed on the lower glass 20 of the panel 40 are formed to correspond to the size of the PDP panel 40. do.

On the other hand, in order to age the small PDP panel 40 through the first to fourth short bars 51, 52, 53, 54 of the aging device of the same PDP panel used in (a) as shown in (b). The first short bar 51 and the third short bar 53 are connected to one side of the bus electrode 14 and the address electrode 22, but the second short bar 52 and the fourth short bar 54 are firstly connected. Due to the length of the short bar 51 and the third short bar 53, the interference between the bus bars 14 and the address electrodes 22 is prevented because the lengths of the short bars 51 and the third short bars 53 are not applied.

Therefore, during normal aging, by applying a high voltage only to the bus electrode 14 on the upper panel without applying power to the address electrode 22 on the lower panel, the plasma formed in the cell of the PDP panel is greatly activated, thereby releasing the phosphors to emit all the cells. It emits light.

When the high voltage is applied only to the bus electrode 14 as described above, since only the first short bar 51 and the second short bar 52 are used, the size of the PDP panel 40 can be coped with.

However, as the size of the PDP panel is gradually increased, a problem arises when the high voltage is applied to only the bus electrode and the aging is poor, thereby requiring the power to be applied to the address electrode.

Therefore, as shown in FIG. 4, the address electrodes 22 are formed by shorting each other on a pattern so that they can be adapted even if the specifications of the PDP panel are changed without being affected by the short bar, and then connected to the address electrodes 22. By shortening the lengths of the third short bar 53 and the fourth short bar 54, even in the case of a small PDP panel 40, the first short bar 51 and the second short bar 52 are not affected. The third short bar 53 and the fourth short bar 54 can be connected to the address electrode 22 of the PDP panel 40 without any problem, and the address electrode 22 can also be used in the case of the large sized PDP panel 40. ) Are all connected to each address electrode so that the aging test of the PDP panel can be performed.

However, since the address electrodes of the lower glass are produced in advance by shorting the pattern on the pattern, there is a problem in that a process of cutting the address electrodes shortened with each other after aging is added.

In addition, since the address electrode is shorted in advance on the pattern, there is a problem that a short defect of the address electrode pattern performed before the panel is not detected.

The present invention was created to solve the above problems, and an object of the present invention is to provide a PDP panel that is already shorted on the pattern when power is supplied to the entire electrode pattern to aging the PDP panel sealed with the upper glass and the lower glass. The PDP panel is connected to the bus electrode of the top glass through a short bar shorter than the bus electrode to secure the moving space of other short bars, so that the PDP panel of various sizes can supply power for aging to both the bus electrode and the address electrode. In providing an aging device.

The present invention made as described above has a first short for supplying power to the X stage during aging by using the X stage short formed on the panel to apply a ground voltage to the bus electrode of the PDP panel during aging of the PDP panel. By making the length of the bar shorter than the length of the bus electrode, it is possible to secure the moving space of the other three short bars so that even if the size of the PDP panel is changed, power can be applied to all electrodes of the PDP panel through the same short bar to perform the aging test. do.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the present embodiment is not intended to limit the scope of the present invention, but is presented by way of example only and the same parts as the conventional configuration using the same reference numerals and names.

5 is a configuration diagram briefly showing a power connection of an aging apparatus of a PDP panel according to the present invention.

In the drawing shown here, the power supply unit for the aging test of the PDP panel and the additional devices for the aging test, such as a table for mounting the PDP panel, are not shown. However, all the electrodes of the PDP panel are used for the aging test. Only the shot bar and the shot bar conveying means for supplying the.

Therefore, parts not covered by the present invention are made of the same configuration as the aging apparatus of the general PDP panel.

When the present invention is described in detail, the length of the bus electrode 14 for supplying power to the X terminal of the bus electrode 14 which is shorted for supplying the ground voltage in the PDP panel 40 as shown in FIG. The movable first short bar 51 is formed to have a short length and is moved by the short bar conveying means 60 according to the size of the PDP panel 40.

As described above, in the case of the first short bar 51, since the X terminals of the bus electrodes 14 are connected to each other in a pattern, the X of the bus electrodes 14 is formed even if the length is shorter than the length of the bus electrodes 14. The power can be supplied to the stage.

In addition, a second short formed to a length corresponding to the length of the bus electrode 14 of the PDP panel 40 and fixed to the aging device in order to supply power to the entire Y-stage of the bus electrode 14 in the PDP panel 40. Bar 52 is installed.

In addition, in order to supply power to all the electrodes on one side of the address electrode 22 of the PDP panel 40, the PDP panel 40 is formed to have a length corresponding to the length of the address electrode 22 of the PDP panel 40. As a result, a movable third short bar 53 whose position is moved according to the size of the PDP panel 40 is provided.

In addition, in order to supply power to all the electrodes on the other side of the address electrode 22 of the PDP panel 40, the PDP panel 40 has a length corresponding to the length of the address electrode 22 of the PDP panel 40. As a result, a movable fourth short bar 54 whose position is moved according to the size of the PDP panel 40 is provided.

Therefore, after mounting the PDP panel 40 to the aging apparatus, the Y-terminal of the bus electrode 14 of the PDP panel 40 is connected to the second short bar 52, and the first short is transferred by the short bar transfer means 60. After moving the bar 51, the third short bar 53, and the fourth short bar 54 according to the size of the PDP panel 40, the bars 51, the third short bar 53, and the fourth short bar 54 are connected to the X terminal and the address electrode 22 of the bus electrode 14, respectively. The aging test is performed by applying power.

At this time, even if the length of the first short bar 51 is shorter than the length of the bus electrode 14, since the X ends of the bus electrodes 14 are all shorted on the pattern, power can be supplied to all the electrodes.

In addition, since the length of the first short bar 51 is short even when the size of the PDP panel 40 for aging test is small, as shown in FIG. 6, the second short bar to the fourth short bar 52, 53, Since the moving space of 54) is secured and does not interfere with each other, even in the case of the small PDP panel 40, all electrodes and the short bar can be connected, and thus an aging test can be performed without replacing the equipment.

In addition, even when the X end of the bus electrode 14 is not shorted on the pattern, the aging test can be performed with minimal change by replacing only the first short bar 51.

As described above, the present invention is connected to the bus electrode of the top glass of the PDP panel which is already shorted on the pattern when the power is supplied to the entire electrode pattern for aging the PDP panel through a short bar shorter than the bus electrode. Even if a PDP panel of various sizes is secured by moving space, there is an advantage in that power for aging test can be supplied to all bus electrodes and address electrodes.

In addition, it is possible to apply power to the entire bus electrode and the address electrode without a short on the pattern of the address electrode, thereby avoiding the subsequent process for cutting the shorted address electrode after the aging test, thereby reducing the number of processes and improving the yield. There is an advantage to that.

In addition, it is possible to easily determine whether the address electrode is short-circuited by enabling power to be applied to the entire bus electrode and the address electrode without a short on the pattern of the address electrode.
