Description

PLASMA DISPLAY PANEL
[Technical Field]
The present invention generally relates to a plasma display panel, and more specifically, to a plasma display panel which is configured to minimize migration.
[Background Art]
A plasma display panel (abbreviated as "PDP") is a device which displays letters and pictures with light emitted from plasma generated during gaseous discharge. The PDP is classified into a DC-type PDP where an electrode for generating plasma is directly exposed to plasma so that conduction current flows directly through the electrode, and an AC-type PDP where an electrode covered with a dielectric material is not directly exposed to plasma so that displacement current flows through the electrode.
Fig. 1 is a perspective view illustrating a disassembled plasma display panel. A general PDP comprises a front substrate 10 and a rear substrate 20. In the front substrate 10, a sustain electrode X and a scan electrode Y are formed for sustaining light emission of cells by inter-discharge in one pixel. These sustain/scan electrodes consist of transparent electrodes (or ITO electrodes) (Xa3 Ya) formed of transparent ITO materials and bus electrodes (Xb, Yb) formed of metal materials. On the sustain electrode X and the scan electrode Y, a dielectric layer 11 and a protective layer 12 are sequentially deposited for insulating a space between a pair of electrodes by restricting discharge current. The sustain electrode X is a common electrode for applying an AC voltage during discharge3 and the scan electrode Y is an electrode for forming wall electric charges by causing discharge at an initial driving. A plurality of stripe-type (or dot-type) barrier ribs 21 are arranged in parallel on the rear substrate 20. Also, an address electrode 22, a dielectric layer 23, a fluorescent layer 24 'are deposited on the rear substrate 20. The address electrode 22 consists of a plurality of sustain/scan electrodes which are alternately arranged, and the fluorescent layer 24 emits visible rays for image display during address discharge. The PDP may be manufactured as a multi-type by connecting a plurality of unit
PDPs in order to make a larger display device. In this case, to reduce a seam region, the sustain(X)/scan(Y) electrodes of the front substrate are fetched to the same direction. The technology of fetching sustain/scan electrodes to one direction may be carried out to combine driving circuits for driving sustain/scan electrodes. Fig. 2 is a diagram illustrating a conventional PDP where sustain/scan electrodes are fetched to the same direction. As shown in Fig. 2, the conventional PDP comprises a front substrate 26 superposed on a rear substrate 27 where a plurality of sustain electrodes (XI, X2, ...) and a plurality of scan electrodes (Yl, Y2, ...) are fetched to one extended portion. Here, the plurality of sustain electrodes (XI, X2, ...) and the plurality of scan electrodes (Yl, Y2, ...) are alternately arranged in a display region 28, and fetched to the extended edge of the front substrate 26 through a connection unit 29. However, the sustain/scan electrodes are fetched to the same direction. For improvement of resolution, an interval difference between each electrode line (XI, X2, Yl, Y2, ...) becomes narrower as the number of lines increases. In this way, if the interval between each electrode line (XI, X2, Yl, Y2, ...) becomes narrower, metallic ions in metal electrodes are diffused into adjacent electrodes, which is called a "migration phenomenon". The migration phenomenon degrades reliability of electrodes and pulls down durability and quality of the PDP. Furthermore, in the conventional PDP, thermal compression is difficult because each pad unit of the sustain/scan electrodes cannot be positioned at the same horizontal direction.

[Detailed Description of the Invention]

The plurality of sustain electrodes (XI, ..., Xn) are commonly connected on the lower portion of the insulating film 403 and fetched through the last sustain electrode Xn.
Fig. 7 is a cross-sectional diagram of C-C of Fig. 4.
As shown in Fig. 7, a sustain electrode X is formed on one upper portion of a glass substrate 100, and an insulating film 101 is coated to cover the upper portion and both sides of the sustain electrode X. Here, a scan electrode Y is which covers the upper portion and both sides of the insulating film 101 is formed on the glass substrate 100.
Fig. 8 is a diagram illustrating a fetch structure of sustain/scan electrodes of a plasma display panel according to a third embodiment of the present invention. In the PDP according to the third embodiment of the present invention, a plurality of scan electrodes (Yl, ..., Yn) and a plurality of sustain electrodes (XI, ..., Xn) are alternately arraunged in a display region 53. The plurality of scan electrodes (Yl, ..., Yn) are fetched to the extended edge of a front substrate 51. The plurality of sustain electrodes (XI, ..., Xn) are commonly connected to the lower portion of the insulating film 50 and divided into two groups to be fetched.
Here, the fetch location is preferably both ends where the plurality of scan electrodes (Yl, ..., Yn) are formed, and the reference number 52 is a rear substrate. In the above-described first and second embodiments shown in Figs. 3a and 3b, the plurality of sustain electrodes (XI, ..., Xn) are merged into one unit, and fetched to one direction through one sustain electrode Xn.
However, in the third embodiment shown in Fig. 8, the plurality of sustain electrodes (XI, ..., Xn) which are divided into two groups are fetched, thereby improving a driving power. Here, the plurality of scan electrodes (Yl, ..., Yn) may be preferably divided into several groups to be fetched. Like the first and second embodiments, the sustain electrode X and the scan electrode Y are separated and crossed by the insulating film 50 in the PDP according to the third embodiment. Fig. 9 is a diagram illustrating a fetch structure of sustain/scan electrodes of a plasma display panel according to a fourth embodiment of the present invention.
