Abstract

PURPOSE:To deal with the high definition of a plasma display panel by using a holed metal plate as a partition or spacer, and also providing insulating layers between the holed metal plate and electrodes. CONSTITUTION:A front glass plate 1 is provided with a cathode 6, and a back glass plate 5 is provided with an anode 7, and a lattice partition 4 of a holed metal is disposed, and insulating layers 2 are disposed between the glass plates 1, 5 and the partition 4 respectively. The holed metal plate 4 has a composition of Ni, a Cr-Fe alloy, an Ni-Fe alloy in a weight ratio of 42:6:50 and its plate thickness is selected in the range of 0.01 to 1.0mm. The coefficient of linear expansion of the metal plate is preferably 80 to 100(X10<-7> deg.C). The hole pattern of the metal plate 4 is preferably provided by corrosion method. PbO-B2O3-SiO2 glass or Al2O3 containing glass and the like is used in forming each insulating layer 2. Each insulating layer is formed on the electrode through printing except on cell holes. A plasma display panel thus formed is capable of dealing with fine cell pitches and is excellent at crosstalk characteristic and the short circuit between anode and cathode would not occur.

There is a drawback that a sufficient discharge gap cannot be obtained unless printing is repeated many times. In addition, especially full dot display F

It is particularly difficult to deal with barrier ribs that completely surround the discharge cell as shown in FIGS. 1 and 4, and requires very advanced technology, which is impractical.

As mentioned above, when there is a partition wall that completely surrounds a discharge cell (hereinafter referred to as a completely closed partition wall) and a part where there is no partition wall between the adjacent cell even in one direction, as in the case of a stripe shape (hereinafter referred to as a completely closed partition wall), , incompletely closed septum), there is a big difference in the following sense.

For example, an FD that emits orange light due to neon gas discharge.
When using the emission color of the rare gas itself, such as P, the emission is limited only to the vicinity of the electrode of the selected cell, so it has been put into practical use even with incompletely closed partition walls, but multi-color or full-color PDPs In this case, since a method is used in which the phosphors are excited to emit light by the ultraviolet rays accompanying the discharge, the ultraviolet rays may leak through incompletely closed partitions, causing the phosphors in adjacent cells to be excited and emit light.

That is, crosstalk or color bleeding is unavoidable, which impairs color reproducibility and resolution, resulting in a decrease in value as a display. In this respect, method A is unsuitable for producing high-definition completely closed partition walls and is not practical for color FDP.

Method B is considered to be relatively easy to adapt to higher definition, but it is expensive and less economical because it uses extremely special photosensitive glass as a material.

Next, a perforated metal plate (partition wall) was sandwiched between the front plate and the back plate, and the periphery was sealed with sealing glass to form an XY matrix DC-FDP.

Comparative Example 1 The partition walls of the DC-PDP shown in Example 1 were formed by thick film printing.

まず、ドツトピッチ 1.0.、抜き穴サイズ0.8X

First, dot pitch 1.0. , hole size 0.8X
A partition wall of 0.8- was created. The height of the partition wall was formed to 0.15 m by overprinting 8 times.

Next, an attempt was made to create a partition wall with the same accuracy as that shown in Example 1, with a tod pitch of 0.2# and a hole size of 0.15 x 0.15 mm. With a pitch of 1.0 mm, slight misalignment or dripping of the printing paste can be ignored, and manufacturing is technically difficult.
The yield rate was much worse than in Example 1. Furthermore, even for those that were successfully manufactured, a sufficient cell aperture ratio could not be obtained for the reasons mentioned above. To give an example, the hole size is 0.2M pitch. IX
The aperture ratio was 25% at O.11NR. In Example 1 described above, the hole size was 0.15×O, 15 m, and the aperture ratio was 56%, so Example 1 was clearly advantageous.

Comparative Example 2 The partition walls of the DC-PDP shown in Example 1 were created by etching a photosensitive plate glass. However, as mentioned above, this material was extremely expensive, and since it was a thin plate glass, it was very brittle, and was inferior to Example 1 in terms of assembly workability.

Comparative Example 3 A C-FDP partition wall was created by drilling holes in general soda-lime glass, etc., as in Comparative Example 2. However, this method required drilling a large number of holes at a high-definition pitch of approximately 0.2 m+. In this case, the dimensional accuracy is considerably lower than that of Comparative Example 2. In addition, considering the brittleness of the thin glass, the workability and assembling workability were inferior to Comparative Example 2, so Example 1
It was considerably inferior.

Comparative Example 4 A perforated metal plate was used alone as a partition without providing an insulating layer on the front glass plate and the back glass plate. As a result, an electrical short circuit occurs between the anode and the cathode, and the light does not light up.In some cases, only the anodes or the cathodes are shorted, causing unselected cells to emit light. It didn't make any sense.

[Effects of the Invention] As described above, the FDP of the present invention in which a perforated metal plate is used as a partition wall and an insulating layer is provided can support a high-definition cell pitch and has excellent crosstalk characteristics. Also,
No electrical short circuit occurs between the anode and the cathode.
