Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new panel structure that enables color conversion and multicolor display in a surface discharge type gas discharge panel for large-sized displays.

The present inventors, from Taru Gansho No. 55-163712',
We proposed a panel structure for large-scale displays using surface discharge or monolithic gas discharge panels.

To put it simply, such a panel should define a gas-filled space (out of a pair of opposing substrates, one of the substrates, which will serve as an electrode support substrate, is a small substrate that is relatively easy to manufacture and has a high manufacturing yield). It is composed of a plurality of composite substrates that are combined with the side end surfaces of the substrates butted against each other, and the other substrate that becomes the cover substrate is made of a large single substrate that is about the same size as the composite substrate. It is characterized by its composition. With such a substrate configuration, the first invention provides a large-sized gas discharge panel that does not require large-scale manufacturing equipment and has a high manufacturing process speed. The present invention aims to perform color conversion or multi-coloring in a large-scale surface discharge panel as described above without requiring large-scale equipment and with a high yield, similar to the prior invention.

Briefly stated, the present invention provides a composite (combined) electrode support substrate and a single cover substrate spaced apart from each other by a predetermined distance in a gas-filled space configured between a composite electrode support substrate and a single cover substrate. A crab light body support substrate is provided, and the light body support substrate is composed of a composite body in which a plurality of substrates each having a crab light body formed thereon are assembled by butting their side end surfaces. It is. Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 and 2 are a plan view of a surface-emitting gas discharge panel according to an embodiment of the present invention and a cross-sectional view thereof taken along the row 0' line.

In these figures, the display panel 10 includes a pair of large glass substrates 12 and 13 facing each other with a gas discharge space 11 in between, and a flat plate-like closed horizontal body and a crab light support substrate 24 sealed in the closed container. It is constituted as a subject. One (upper) glass substrate 13 that functions as a cover substrate has a single plate configuration, but the other (lower) glass substrate 12 that functions as an electrode support substrate has, for example, a 20×20
=4 glass substrates 121,1 with a size of about 400
22, 123, and 124 are combined in such a manner that the side edges of two adjacent sides are butted against each other. In addition,
For convenience of explanation, such a substrate 12 will hereinafter be referred to as a combination substrate. The four glass substrates 121, 122, 123, 1
Each of the electrodes 24 has a plurality of Y electrodes 14 extending in the horizontal direction on a substrate, and furthermore, a plurality of has been done.

On top of these × electrodes 16 is a dielectric layer 17 made of a vapor-deposited film of citric acid gas, aluminum oxide, etc.
is provided thereon, and a surface layer (not shown) consisting of a vapor-deposited film of magnesium oxide (Mg◯) is further coated thereon. As shown in the figure, one end of the Y electrode group and the one end of the It is exposed to the outside so that it is connected to the drive circuit. It is also possible to make each × electrode and each Y electrode on two substrates on the same line function as one × electrode and one Y electrode by electrically connecting them inside or outside the panel, Alternatively, each may function as a separate and independent electrode. Note that the Y and X electrodes 14 and 16 are both made of Cu-
It is formed by patterning a vapor-deposited conductive layer of mountain alloy or the like by photolithography, and a sealing material 18 made of low melting point glass or the like is provided between the cover glass substrate 13 and the combination substrate 12 around it. A mixed gas of Xe-He is sealed through the chip tube 19 and the exhaust port 20 in the gas space 11 which is sealed oppositely. On the other hand, a light support substrate 2 sealed in the gas space 11
4 is a predetermined gap between the combination substrate 12 and the like, for example, 0.1.
Electrode supporting substrates 121 and 12 are provided with legs separated from each other.
A small board 24 of 1 willow with a thickness of 18 x 18 = 324 and the same number as the combination of 2,123,124 (4 boards)
1,242, 243, and 244 are combined in the same manner as the electrode supporting substrate.

Crab light body 240 for these four substrates 241 to 244
If the target panel is a single-color display panel whose sole purpose is color conversion, a method is adopted in which a crab light body with the desired luminescent color is formed on the entire surface of the substrate, or if the target panel is a single-color display panel whose sole purpose is color conversion. In the case of a panel intended for display, blue, red, and green light is emitted partially on the substrate surface corresponding to each discharge area formed by each intersection of the Y electrode group 14 and the × electrode group 16. A method of appropriately forming each colored crab light body is adopted. Processing such a photoluminescent material does not require large-scale equipment, so there is a great cost advantage. In this example, since a mixed gas of Xe and Xe is used as the discharge gas, the crab light material passed through this gas is (Y・Gd)803:Eu for red, and Shigeru MgN, for blue. 4
023:Eu and Zn2Si04:Eu for green color are recommended. Further, in FIG. 2, the reference numeral 25 indicates a
26 indicates an adhesive. Therefore, the combination substrate 12
A large supporting substrate 21 for reinforcing the panel is arranged on the lower surface of the panel. On this supporting substrate 21, low-melting glass 22 for adhesion is provided at the peripheral portion thereof and at corresponding locations of the abutting portions of each of the electrode supporting substrates 121 to 124, and these adhesive materials 22 are used to bond four sheets. Bonding for combining electrode supporting substrates and the combined substrate 1
2 and a support substrate 21 are integrated. In addition, 2
3 is a through hole through which the tip tube 19 is inserted. Now,
To briefly describe one example of a method for assembling such a large display panel, first, four individually manufactured electrode supporting substrates 121, 122, 123, and 124 are placed with their adjacent side end surfaces butted together. A plurality of adhesives 22 are placed at predetermined positions on the support substrate 21 that has been remounted in advance.

At this time, the abutted portions of the four electrode supporting substrates are positioned on the adhesive material 22, and the chip tube 19 is positioned in the through hole 23, respectively. Thereafter, the sealing layer 18, the adhesive 26, and the spacer 25 are placed at predetermined positions on the four electrode support substrates, that is, the combination substrate 12, and the cover glass substrate 13 is placed thereon. At this time, four crab light support substrates 241, 242, 243, and 244 are bonded to predetermined positions on the inner wall surface of the cover substrate with an adhesive (not shown) with their respective end surfaces butted against each other. has been done. When appropriate pressure and heat are applied to this laminated structure, the adhesives 22 and 26 and the sealing material 18 melt, thereby adhering (joining) the respective substrates and sealing the gas space 11. will be done. Thereafter, after bonding the chip tube 19 to the exhaust port 20 of the electrode support substrate 124, discharge gas is filled into the gas space 11 through it, thereby completing the required large-scale color conversion or multicolor gas discharge display panel. It turns out. Regarding the driving method of such a large display panel, if the electrodes on the same line on two adjacent electrode supporting substrates are electrically connected externally, matrix G address driving on the entire surface of the panel as in the conventional case can be performed. In addition, in the case where the electrodes are not electrically connected, partial matrix address driving is possible for each electrode supporting substrate.

In the former case, the driving circuit can be simplified, and in the latter case, although the driving circuit becomes complicated, high-speed address display can be achieved. As a result, the corresponding crab light body is excited by the ultraviolet rays generated as a result of the discharge in the addressed discharge region, so that a desired luminescent color can be visually observed. Although one embodiment of the present invention has been described above, the essence of the present invention is not limited to this embodiment, and various modifications are possible. For example, the combined number of electrode supporting substrates and crab light body supporting small substrates is not limited to the above-mentioned four, but may be more than four. In this case, the number of both substrates does not need to be the same. Further, although the panel reinforcing support substrate 21 is not necessarily required, in a structure using this, the combination substrate 12
Since the chip tube 19 can be provided on the support substrate 21 by hermetically sealing the periphery thereof to the support substrate 21, the present invention can also be applied to such a panel. Now, as is clear from the above description, the present invention combines a plurality of electrode supporting substrates, which are relatively easy to manufacture and have a high manufacturing yield, with the side end surfaces of each substrate butted against each other, and In a surface discharge type gas discharge panel that enables a large display in which a single large cover substrate is disposed oppositely above the combination substrate, a gas-filled space formed between the combination substrate and the cover substrate is ,
The present invention is characterized in that a combined crab light body support substrate having the same form as the combination substrate is enclosed, and the crab light body forming process of each small single substrate constituting the combination crab light body support substrate is performed. It does not require large-scale manufacturing equipment and can increase manufacturing steps.

Therefore, it is extremely useful in producing large-scale color conversion or multi-color gas discharge panels.
