Description

Manufacturing Method of Plasma Display Panel

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly, to a method of manufacturing a plasma display panel in which an integration degree is improved by reducing an interval of each cell electrode formed on a front substrate.

In general, a plasma display panel (PDP) is composed of an array of discharge cells capable of independently discharging, and independently discharges each discharge cell according to an external electrical signal to reproduce a desired video signal. It is a flat panel display device.

Since the PDP can have a thickness of about 1 cm or less (including the thickness of the substrate glass) between the rear substrate and the front substrate, the thickness and weight of the display device can be significantly reduced compared to the CRT display device using an electron gun. In addition, it has the advantage of improving the narrow viewing angle which is the weakest point of the liquid crystal display device.

1 is a view for explaining a PDP according to the prior art, wherein the PDP includes a back substrate 1 having an address electrode 2 covered with a first dielectric layer 3; A discharge sustaining electrode, which is disposed to face the rear substrate 1 and is formed of a transparent electrode 5 and a bus electrode 6, is formed, and a second dielectric layer 7 and a protective layer 8 are stacked on the discharge sustaining electrode. The front substrate 4 has a structure in which an independent discharge space is defined and interposed between the partitions 9 for preventing crosstalk between pixels.

In the above, the discharge holding electrode is formed in the form of a strip on the front substrate, and in detail, as shown in Figure 2, as a transparent electrode for causing a discharge, the sustain electrode (11) and the scan (Scan) The electrodes 22 are formed to be repeated, the sustain electrodes 11 are formed to be connected to each other, and the bus electrodes 13 for maintaining the voltage applied to them on the sustain electrode 11 and the scan electrodes 12. ) Is formed. Accordingly, each of the discharge sustaining electrode cells is composed of one sustain electrode 11, a bus electrode 13 formed thereon, and one scan electrode 12, and a bus electrode 13 formed thereon. The stin electrode 11 and the scan electrode 12 are formed to maintain a distance by d ₁ , and the electrode cells are formed to maintain a distance by d ₂ .

Here, the same voltage is applied to all the sustain electrodes 11, and when a predetermined voltage is applied to the scan electrodes 12, a discharge phenomenon occurs between the sustain electrode 11 and the scan electrode 12.

However, as the discharge phenomenon between different electrodes adjacent to each other between adjacent electrode cells according to the related art according to the related art occurs, malfunction occurs and reliability is lowered. To solve this problem, d ₂ is greatly increased. In this case, there were problems in high definition and high efficiency.

Therefore, the present invention forms a sustain electrode and a scan electrode for generating a discharge on the front substrate, the neighboring electrode cell by forming the sustain electrode and the scan electrode so that the adjacent electrodes between the neighboring electrode cells are the same It is an object of the present invention to provide a method for manufacturing a PDP that can prevent a discharge phenomenon from occurring.

In addition, an object of the present invention is to provide a method for manufacturing a PDP that can improve the degree of integration by forming more electrode cells on the substrate by reducing the distance between the electrode cells.

In addition, the present invention provides a method of manufacturing a PDP that can improve the overall brightness of the display device by preventing the discharge generated between neighboring electrode cells and increasing the discharge area by widening the sustain electrode and the scan electrode. The purpose is to provide.

EXAMPLE

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

3 is a view for explaining a method of forming a sustain electrode and a scan electrode formed on the front substrate according to the present invention, the plurality of sustain electrodes 21 and the scan electrode having a stripe shape on the front substrate 20 (22) are formed, and bus electrodes 23 are formed on each sustain electrode 21 and the scan electrodes 22 to maintain a voltage applied to those electrodes. In addition, the adjacent sustain electrode 21 and scan 22, the electrode "was has a distance by, where, d _1, d ₁ is the same size as the spacing d ₁ between the conventional sustain electrode and the scan electrode to be.

In the drawing, each discharge sustaining electrode cell is composed of one sustain electrode 21, a bus electrode 23, and a scan electrode 22, for example, the sustain electrode in any one of the discharge sustaining electrode cells; The sustain electrode in another neighboring discharge sustaining electrode cell is formed to be close to each other, and in the case of the scan electrode, it is formed to be similarly similar between neighboring discharge sustaining electrode cells.

Thus, each of the discharge sustaining electrode cells, and have a spacing of as much as, the d ₂ interval between the discharge sustaining electrode cell in accordance with the present invention, d ₂ is more than the spacing d ₂ between the conventional discharge sustaining electrode cell short. That is, compared to d ₁ or d ₁ ′, which is a distance between the sustain electrode 21 and the scan electrode 22, d _{2, which} is a distance between the conventional discharge sustaining electrode cells, is about 3d ₁ , but the discharge according to the present invention is performed. The interval d ₂ ′ between the sustain electrode cells is twice as large as that of d ₁ . Therefore, by reducing the distance between the conventional neighboring electrode cells, the number of discharge sustaining electrode cells formed on the substrate can be increased to improve the degree of integration.

In addition, by reducing the distance between the discharge sustaining electrode cells, the width of the sustain electrode and the scan electrode can be increased, thereby increasing the discharge area, thereby improving the overall brightness of the PDP.

As described above, the PDP manufacturing method according to the present invention forms a sustain electrode and a scan electrode such that adjacent electrodes between neighboring electrode cells are positioned at the time of formation of the discharge sustaining electrode cells formed on the front substrate. As a result, it is possible to prevent a discharge phenomenon between adjacent electrode cells from occurring, and also to improve the degree of adhesion by reducing the distance between the respective electrode cells, thereby improving the overall brightness.

Meanwhile, although specific embodiments of the present invention have been described and illustrated, modifications and variations can be made by those skilled in the art. Accordingly, the following claims are to be understood as including all modifications and variations as long as they fall within the true spirit and scope of the present invention.
