Description

METHOD FOR FABRICATING MULTI-PDP
[Technical Field]
The present invention relates to a method for manufacturing a multi-plasma display panel! In particular, the present invention relates to an improved method for manufacturing a multi-plasma display panel wherein a structure is formed and cut into a required size, and then a subsequent process is performed to manufacture a multi-plasma display panel. [Background Art] A plasma display panel has been used widely as a flat panel display device together with other display devices such as a liquid crystal display panel and an organic electro luminescence panel.
However, the plasma display panel is inefficient in enlargement of a screen as a single panel. As a result, studies have been done to overcome the limitation by assembling a plurality of panels two-dimensionally to embody a desired size of the screen.
For example, as shown in Fig. 1, a wide screen display device using a plasma display panel comprises four different panels A, B, C, and D whose adjacent sides contact each other.
In this case, a seam area 5 resulting from configuration of a buffer material is formed between the panels. In the seam area 5, images are not projected.
Each plasma display panel of Fig. 1 has a structure wherein a front panel is sealed with a rear panel. Here, the front panel has a cross-section shape as shown in Fig. 2 and the rear panel has a cross-section shape as shown in Fig. 3. there structure is formed after the front panel and the rear panel are previously cut into a required size. In particular, the front panel 2 comprises a glass panel 10 whereon a transparent electrode 12, a bus electrode 14, a dielectric layer 16, and a protective film 20 are formed. The transparent electrode 12 is prepared for configuration of X and Y electrode, and the protective film 20 is commonly formed of MgO.
Furthermore, the rear panel 4 has a glass panel 30 whereon an address electrode 32, a rear dielectric layer 33, a separation wall 34, and a fluorescent substance 36 are formed.
In the above-described conventional multi-plasma display panel, all structures are required to be formed to the edge of the glass panel in order to reduce seam area 5.
However, due to the edging effect during an actual printing process or a deposition process of protective film, uniformity is degraded at the edge of the panel, thereby causing unstable discharge on the surface.
Moreover, in the conventional multi-plasma display panel when the structure is formed to the edge using the previously cut glass panel to form the structure, a mask used in the process is damaged, thereby shortening the duration period of the mask. [Detailed Description of the Invention]
Accordingly, it is an object of the present invention to provide a multi-plasma display panel by previously performing a process for forming a structure on a glass panel and then cutting the glass panel into a required size in order to minimize the seam of the structure as well as to insure the uniformity. It is another object of the present invention to provide a method for manufacturing multi-plasma display panel comprising a process for forming a structure on a glass panel while minimizing the damage of a mask.
In an embodiment, there is provided a method for manufacturing a multi-plasma display panel, comprising a process for fabricating a front panel and a rear panel separately and sealing the panels, wherein the front panel and the rear panel are cut into a required size, and then a subsequent manufacturing process is performed on the cut panels.
Preferably, the cutting process on the front panel is performed after formation of a dielectric layer, after formation of a sealing line or after formation of a protective film.
Furthermore, the cutting process on the rear panel is performed after formation of a separation wall, after print and dehydration of a fluorescent substance, or after sintering of the fluorescent substance. [Brief Description of the Drawings]
Figure 1 is a plane block diagram of a wide screen plasma display device.
Figure 2 is a cross-sectional view of a front panel. Figure 3 is a cross-sectional view of a rear panel.
Figure 4 is a flow chart illustrating a method for manufacturing a multi-plasma display panel according to an embodiment of the present invention. [Preferred Embodiments of the Invention]
In an embodiment, a glass panel is used in a manufacturing process of a multi- plasma display panel comprising a front panel and a rear panel, whereon a predetermined process for forming a structure is performed on the glass panel having a larger size than its original size or the final cut size.
The specific process will be described with reference to Fig. 4, and numerical references of each element are cited with reference to Fig. 2 and 3. In order to fabricate a front panel 2, a glass panel 10 has a size larger than the final cut size or its original glass size.
The front panel is fabricated through the following process: formation of a transparent electrode 12 (S10), formation of a bus electrode 14 (SI 2), formation of a dielectric layer 16 (SI 4), formation of a sealing line (SI 6), and formation of a protective film (SI 8). Here, the transparent electrode 12 is commonly patterned by photo lithography process, and the bus electrode 14 is formed on the transparent electrode with a stacked structure of an aluminum or a chromium-copper-chromium layer. A deposited pair of the transparent electrode 12 and bus electrode 14 form a X or Y electrode for sustaining discharge.
The dielectric layer 16 is formed by printing and sintering glass powder paste on a marked electrode.
A sealing line (not shown) is formed by annealing a low melting point frit glass material. The protective film 20 is formed by commonly vacuum depositing a MgO material.
The front panel may be cut into a desired size depending on the manufacturer's purpose by selecting one of the timings Al after formation of the dielectric layer 16, A2 after formation and sintering of the sealing line, or A3 after formation of the protective film 20. Since the structure pattern is oversized than the required size in each timing, the cutting process is not affected by the edging effect but the resulting structure whose region is cut has the same uniformity as that of the rest region.
Moreover, the resulting structure is not formed to the edge of the mask during the process, thereby preventing damage of the mask. Similarly, the fabricating process of the rear panel 4 also requires a glass panel
30 having a size larger than the final cut size or its original glass size.
By using the glass panel 30, the rear panel 4 is fabricated through the following sequences: formation of an address electrode 32 (S20), formation of a rear dielectric layer (S22), formation of a separation wall 34 (S24), and formation of a fluorescent substance 36 (S26). The rear panel may be cut into a desired size depending on the manufacturer's purpose by selecting one of the timings Bl after sintering and formation of the separation wall, B2 after print and dehydration of the fluorescent substance 36, or B3 after sintering of the fluorescent substance 36. Like the front panel, the rear panel 4 whose region is cut has the secured uniformity, and the damage of the mask is prevented.
As described above, when the front panel and the rear panel are fabricated and cut into a required shape, the front and rear panels are aligned, and aged through sealing/exhausting/gas injecting process. [Industrial Applicability]
In this regard, according to an embodiment of the present invention, after main structures that affects discharge are formed, the cutting process is performed on the resulting structures, thereby insuring uniformity of the edge of the structure which is adjacent to a seam area. As a result, discharge may be stabilized, reliability may be enhanced, and the seam may be minimized.
Moreover, the damage of the mask during the process is minimized to extend the duration of the mask, thereby reducing the manufacturing cost.
