Abstract

PURPOSE:To uniform the gap between an upper and a lower substrate after fixation by adhesion and to improve the quality of display by curing thermally resin for adhering the upper and lower substrate together with visible or infrared light. CONSTITUTION:A sealant 36 for adhering glass 31 where an element is formed and a facing substrate 32 together is cured by being irradiated with light 34 from a lamp 33. A panel is clamped by thin glass 35 and a flat metallic plate 38 and pressurized by a spring 37 to uniform the gap between the upper and lower substrates 31 and 32. Black particles are mixed with the sealant 36 to accelerate its curing and the glass hardly absorb the visible light and infrared light, so the sealant 36 is cured without any rise in the temperature of the glass substrate 31.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is based on two substrates (glass or
This invention relates to a manufacturing method for panel assemblies of plastics.

Conventionally, when assembling a panel, there were roughly six types of methods for fixing the two upper F glass plates in a layered manner. How to use and seal.

烙) A method of sealing using 1 ml of heated resin.

(Ultraviolet-like curing: 1. A method of sealing by irradiating the inner surface with ultraviolet light.

For other methods, temperature-curing resins generally take a long time to harden, while resins with a short hardening time require a pot-liquid (mix with a curing agent, etc.) and cure after the curing process has started. [i4])
Current springs are short and have poor construction properties, and are not easy to assemble, and are generally panels? Regarding the assembly part 1/C, it is best to assemble the upper board with glass or plastic of the same material. , the element is 1'
``Due to the fact that impurities in the glass have an effect on the temperature of the glass, glass with fewer impurities may be used for the substrate used to make the element. However, on this floor, there is a substrate on which the elements are made, and a substrate facing the plate.
The installed Sekiuri sword 1 and other glass made of Tatomi are often used for drinking. In particular, when making a panel that is difficult to cast a shadow even when the tVt crystal panel is lit, it is necessary to select glass made of a material that is hard to break and has dry spots. FIG. 1 is a diagram showing the structure of an active matrix liquid crystal display panel.
The lower glass 14 appears to be 1d from the position of the reflector 15 to the position 2 of the distance between the liquid crystal layer 12 and the reflector 13.
By reducing the thickness of the polarizing plate 15, a quiet house 1
It's 6 and Kyo, so don't stand out.

As mentioned above, we will discuss the 7-rule method when the two substrates are of slow material and have the same thickness. The vA branch of one pin to be sealed must be heated to about 400 degrees Celsius, and when the base is applied with a different setting as in the previous 6th example, it was scraped to the point where the panel was cooled to AJ. If a crack appears, the result will be 7.Also, the temperature of the glass will be 100℃ to 150℃ even in the scene where the heat conversion side fat is cured 7j 9, ultraviolet ray hardening 1 and resin sound is used. Figure 2 shows the seven layers of the panel identified using a conventional jig.This jig is placed in a furnace and heat hardened. However, the gap between the top and bottom boards of the panel is no longer uniform.

The method based on ultraviolet field curing is as follows: ``One shot that heats the mouth is not enough, but the glass absorbs all of the ultraviolet rays, raising the temperature of the glass.'' In this way, for panels where the gap between the upper and lower boards is not uniform, '1
When Vj-crystal purple is inserted, the liquid crystal coating 1111g force makes the gap between the four sides of the upper and lower substrates, that is, the j speed of the liquid crystal layer, uniform, but the ratio and force of the glass are different. heat(
There is a shift in the expansion rate.''Yui G', the jν of the panel does not form a tree, so the panel appears colored. Also, if you put an LCD on the panel, you can use glass or stickers on the VC.
Long-term heating of the mind can cause shavings and long-lasting damage, and this drawback can be avoided by heat-curing chewing. Those cured for a long time at 10 uC or more F did not have any problems with the cell thickness, but they suffered from the drawback of fear of aging of the panel.

The present invention overcomes the drawbacks of the conventional technology, and its purpose is to:
The 7G fixed wave's upper and lower display is 4-4 times above the gap, and the display heavy duty is immersed, and the aging 1 raw and strong 1" are also elaborate LC Hanel meeting 1. The lower figure 446 is a 1ζ diagram showing the lamination method according to the invention, and shows the glass 31 on which the entire element is formed, the same substrate 32, and the seal j for 2d to J.
It is solidified by a vine that irradiates light 34 from a tl 36 k lamp 53.

In order to make the gaps between the upper and lower bases 31 and 52 uniform, the panel is covered with thick glass 35 and flat gold maple handles 38, and pressure is applied to the panel. In the pressure C process, spring 37 and 971O are obtained, black carbon black is mixed in the sealant, and light (low light, infrared ratio) is mixed.
The sound is absorbed for a long time, and the temperature near the sealant increases locally. Since glass has no ability to absorb light from the town and outside the walls, the degree of weave of the crow plate does not increase. When fixing in contact using a method using a furnace as shown in Figure 2, the temperature of the upper glass plate also rises, and when the upper F glass plate is returned to the contact fan fixed with the panel R Naotane, the upper F glass Due to the difference in expansion rate, the upper 1.- glass is not parallel.The condition of Neutling when he urinated at 120℃ using the conventional method and the ++# l0Ik of the panel. Figure 4 shows the difference. Quartz glass 7+1 and Pyrex glass a

bends. At the center and edges of the panel, approximately 5μ to 7μ i
The current lid came out. Figure 5 shows the case of contact fixation using the method of the present invention, and it is believed that the temperature of the vitreous body hardly increases, so it is extremely small as compared to Newton's ring. On the other hand, in the panel, glass fiber is used to make the gaps between the glasses uniform, so the upper F

Fig. 6 is another example of the present invention, in which the plate used to press the spring l from the upper and lower blades is made of glass 69 instead of metal. For example, a metal plate reflects light but retains some of the absorbed light, so Y crystal 1 does not exist.
-However, I would like to point out that removing this point is an example of 46 failure.The invention is effective not only for glass substrates but also for substrates with different coefficients of thermal expansion, such as plastic silicon substrates. In addition to this, even if it is used in parallel with furnace heating, it is also considered as an axis of the present invention.
