Abstract

The present invention relates to the structure of an electrode in a plasma display plate (PDP) of a TV, a monitor, and various display devices. Electrodes connected to the power source in the horizontal and vertical directions are respectively provided on the upper and lower portions of the dielectric layer, and any one electrode surface is cut out so that the electrodes do not overlap each other at the intersection of the lower and upper electrodes. The electrode structure is designed so that no electric field is formed. This structure is discharged between the upper and lower electrodes on the surface of the dielectric layer by the connecting power in the horizontal and vertical directions. This structure is an electrode structure of high efficiency in terms of electric field energy because unnecessary electric field is not formed in the dielectric layer irrespective of discharge. This structure consists of two electrodes separated by a dielectric layer on the discharge surface, the center electrode part and the outer electrode part. These inner island electrodes and outer electrodes are connected to a power source in the horizontal and vertical directions, respectively. This island structure can maximize the discharge surface between the electrodes to increase the amount of plasma generated. In addition, the structure of the island can be produced in a flat type and irregularities.

The planar form simply installs electrodes on the top and bottom surfaces of the dielectric layer, respectively. The uneven type is a structure in which any part of the island portion or the outer shell portion of the electrode protrudes. This electrode structure is used as the upper or lower electrode structure in the PDP.

Description

PD Island's Island Electrode Structure

The present invention is a highly efficient electrode structure used in plasma display devices and so-called PDP devices used in TVs, monitors and various flat panel display devices. Among the electrode structures of the past PDP devices, the electrode structure on the back side is provided with electrodes in the horizontal (X) and vertical (Y) directions above and below the dielectric layer, and the electrode structures are discharged by connecting them to a power source in the X and Y directions, respectively. Designed. However, in such a structure, a strong electric field is formed inside the dielectric layer of the intersection of two electrodes separated by the dielectric layer, which is very disadvantageous in terms of efficient utilization of the electric field. The present invention is the electrode structure to remove the intersection between the two electrodes in order to compensate for this disadvantage. That is, it is an island type electrode structure that cuts out any one electrode surface so as not to overlap at the intersection of two electrodes connected in the horizontal and vertical directions, thereby suppressing the formation of an unnecessary electric field inside the dielectric layer and making the discharge surface as wide as possible. . In addition, unlike the structure of the past, not only the connection method with the power source, but also because the shape and structure of the island can be varied, it is possible to adopt the electrode structure having the optimum efficiency.

1 is a conceptual diagram of an island type electrode structure. The electrode connected to the power in X and Y direction is composed of the island in the middle and the outer electrode as shown in the figure. In this case, each electrode surface is separated above and below the dielectric layer, but is designed to not overlap each other at the intersection of the electrode surfaces above and below. This is different from the electrode structure introduced in the past. As shown in the figure, the island electrode 1 and the outer electrode 3 are installed on the top or bottom of the dielectric, but one is installed on the top or bottom surface. The first picture shows an island electrode on top of the dielectric layer, and the second picture shows an island electrode on the bottom of the dielectric layer. In addition, connecting electrodes 2 and 4 are provided on the same surface as the respective electrodes. If necessary, the connection directions of the electrodes of X and Y can be changed as shown in Figs. In addition, the position of the connecting portion can be arbitrarily selected or two or more positions can be provided.

2 is a perspective view of a unit discharge surface of an island electrode structure having a planar discharge structure. In the bottom of the dielectric layer, the electrode of the island is installed and the outer surface of the electrode is installed. Of course, the upper and lower surfaces of the dielectric can be installed by installing the island and the outer electrode. In addition, the connecting portions 2 and 4 of the electrodes may also take different directions. The power supply of the connecting electrode is shown as 5 and 6, respectively, along the direction.

3 is a perspective view and an optional cross-sectional view of the unit discharge surface of the uneven island electrode structure. The islands show protruding positive islands (FIG. 3A) and concave negative islands (FIG. 3B). The cross section of each figure shows the structure of the dielectric layer relative to the position of the electrode.

As described above with reference to FIGS. 1-3, various methods may be used depending on the structure and the use of the PDP in the form of the electrode and the connection method of the power supply. In addition, the shape of the electrode can take island electrodes of various shapes such as toroidal rings in addition to the rectangular structure as described above. In particular, the electrode structure can be provided on the front plate or the back plate of the PDP. In the case of installing the electrode on the front plate, in order to increase the transmittance of visible light, the electrode is installed using a transparent material at an appropriate part.

The present invention is a high efficiency and high brightness electrode structure installed on the front plate or the back in the conventional PDP device. It is an electrode structure designed to increase the discharge efficiency by cutting out any one electrode surface at the intersection portion in the structure of the two electrodes connected in the horizontal and vertical directions separated by the dielectric layer. Compared to the structure of the conventional PDP, a variety of electrode structures of a new type with the purpose of dramatically increasing the light emission brightness and efficiency are possible, and thus the next generation PDP that can secure the maximum discharge surface and the light emitting surface.

Conventional plasma flat panel display devices have a very low luminance, high efficiency, high manufacturing cost, and high power consumption, and thus are constrained in practical use as TVs and various display devices. In particular, the similar electrode structure of the past related to the present invention was not adopted as the electrode structure of the PDP due to the extremely poor efficiency due to the formation of a strong electric field inside the dielectric layer.

Since the electrode structure of the present invention can be in various forms, a systematic study for optimal design is required.
