Description

Bus electrode of AC plasma display panel

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus electrode of an alternating current plasma display panel. More particularly, the present invention relates to a bus electrode of an alternating current plasma display panel in which an installation form of a bus electrode is provided to improve conductivity on an ITO electrode on a front glass substrate. It is about.

In general, a plasma display panel is a device that displays characters or graphics using light emitted from a plasma generated during gas discharge. The electrode structure of the plasma display panel is largely alternating with a direct current type, an alternating current type, and a direct current type. Types are classified as mixed types.

The difference between the direct current type and the alternating current type is distinguished by whether the electrode is directly exposed to the discharge plasma or indirectly by the dielectric layer.

FIG. 1 is a view showing a bus electrode in a typical AC plasma display panel, in which an indium tin oxide (ITO) electrode 12 is provided in a dielectric layer 14 on a front glass substrate 10. The surface of the dielectric layer 14 is coded with a protective film layer 16 made of a sputtering resistant material (for example, MgO).

Here, the ITO electrode 12 is a transparent and conductive material while having a very high resistance. This resistance causes a voltage drop when an external voltage is applied to the ITO electrode 12.

In order to minimize such a voltage drop, a bus electrode 18 of a metallic material having high electrical conductivity is connected to the ITO electrode 12 on the ITO electrode 12 as the sustain electrode provided on the front glass substrate 10 in the related art. Formed side by side.

By the way, the bus electrode 18 is typically formed by printing on the ITO electrode 12. The conventional method does not guarantee the accuracy of the width and height of the bus electrode 18. If the panel is large, there is also a problem with the alignment.

In particular, when the height of the bus electrode 18 is not constant or misaligned, misdischarge may be caused during plasma discharge, thereby causing a problem that the bus electrode 18 adversely affects the initial discharge.

Accordingly, an object of the present invention is to provide a bus electrode of an AC plasma display panel which is capable of precisely adjusting the width and height of a bus electrode and preventing misalignment of the electrode. There is this.

According to a preferred embodiment of the present invention to achieve the above object, in the AC plasma display panel having an ITO electrode and a bus electrode, the bus electrode is installed on the front glass substrate at the same height as the ITO electrode and the A bus electrode of an AC plasma display panel provided in an ITO electrode is provided.

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

2 is a diagram illustrating a bus electrode structure of an AC plasma display panel according to an exemplary embodiment of the present invention, and FIG. 3 is a plan view of the ITO electrode and the bus electrode illustrated in FIG. 2.

The difference between the figures and FIG. 1 lies in the installation form of the bus electrode 18.

That is, in FIG. 1, the bus electrode 18 is patterned on the ITO electrode 12 provided on the front glass substrate 10. In FIGS. 2 and 3, the ITO electrode 12 and the bus electrode 18 are the same. One side of the ITO electrode 12 and the bus electrode 18 is provided together on the front glass substrate 10 at the height, except that the bus electrode 18 is provided in the ITO electrode 12.

According to the embodiment of the present invention configured as described above, as the bus electrode 18 is formed in the ITO electrode 12 at the same height as the ITO electrode 12, the alignment of the electrodes is well aligned so that the bus electrode 18 during the initial discharge. There is no misdischarge caused by).

In the embodiment of the present invention, as shown in FIGS. 2 and 3, the bus electrode 18 occupies only a predetermined portion of the ITO electrode 12. However, the position of the bus electrode 18 may be changed within the ITO electrode 12. It may also take up the entire space.

According to the present invention as described above, by forming a bus electrode having the same height as the ITO electrode inside the ITO electrode, the width and height of the bus electrode can be precisely adjusted according to the patterning of the ITO electrode, and the problem of misalignment of the electrode is also easy. Resolved.

In addition, since the bus electrode is formed inside the ITO electrode, printing production can be easily performed.

In addition, this invention is not limited only to the above-mentioned embodiment, It can implement by modifying and modifying within the range which does not deviate from the summary of this invention.
