Description

476017 Refers to Uitul, a plate crystal liquid made by Youji and French methods, "Ming Ming Jing Fa i 背 本 明月 发 # Five hair plywood table method base has square glass. Made of glass, Next, put the heat, the lifting plate, and the surface, and apply the film on the crystal to apply and paste the film like a thin film on the ground. According to the technique of glue all, the first kind is used to set the face side first by shrinking, and the inner periphery is facing forward, or the agent is filled and separated from the interstitial theory. Whether there is a non-directional film, both sides will be larger first. It is covered by the plate, but the glass is not empty, or the glass is placed in the transparent plate, and the glass body is compounded with glass glue, so that it can be used again. Put two rows on top of the board, and then the same base, glass, rear glass on the 11 liquid e 禺 C: / C charge the surface of the board to make it into the shape of the substrate glass-based glass substrate into the glass pressure Place the crystal pressure liquid and add it again and again, and then borrow it again. Draw}, the glass is the same as the two, so that the crystal and the liquid enter, and the rest The agent is out of the compartment, and the flat and variable flat expansion drum on the board is placed on the base of the glass. The outer glass of the drum is exposed to the glass and the two crystals make the rust but not add pressure. It is easy to place when it is installed. Because of the other pressure plate, Gage will be able to make glass flat and glassy, but they are splitting each other. They rely on breaking and holding the pressure plate to ensure that the glass is held. The glass is not guaranteed, so the glass plate is available. The two materials used in the glass are not applied to the material force, and each steel plate will not be based on the normal force of the steel because of the equal plate. According to the method, there is no installation and installation. 9 prj,, the time is high, the glass is high, the glass is glassy, and the two are in the combination of the sealed plate, the glass, the glass, and the glass granule compartment. Compared with the high-end method, the bodyless glue base is made of glass and the two are used.

Description of the invention (2) Outline of the invention: In order to improve the various shortcomings of the above-mentioned custom, the inventor upholds many years of experience in the industry, and after many years of continuous research and experiment, he finally developed a design Invented method and device for manufacturing liquid crystal panel. It is an object of the present invention to provide a method for manufacturing a liquid crystal panel, which is mainly composed of a spacer sandwiched between the spacers and the periphery sealed together by a colloid. A panel formed by combining upper and lower glass substrates is placed in cooperation with the panel. Then, a vacuuming operation is performed to evacuate the air in the glass substrates, and at the same time when the vacuum is evacuated, the elastic membrane on the upper glass substrate will be pressed against the upper glass substrate. So that the upper glass substrate can be flatly pressed against the spacer by the pressure of the elastic membrane, and the gel on the φ side of the upper and lower glass substrates can also be heated and softened by the heating device to make the upper and lower glass substrates softer. The distance between the periphery of the lower glass substrate can be equal to the particle size of the spacer, so that the distance between each part of the upper and lower glass substrates is equal, and the colloid is hardened, and then taken out to fill the liquid crystal operation. After the filling is completed, Place it in the fixture, and repeat the above steps at the same time, so that the excess liquid crystal in the glass substrate can be squeezed out of the glass substrate by the pressure of the elastic film, and the upper and lower glass substrates It can return to the state of being close to the spacer and being parallel to each other without any unevenness on the surface. This object is to provide a method for manufacturing a liquid crystal panel, in which a panel formed by combining glass substrates is evacuated. When not injecting liquid crystal, you can input nitrogen or heat at the same time, so that the moisture or other gas between the upper and lower glass f substrates can be completely exhausted, so as not to remain between the upper and lower glass substrates. &Quot;

A hollow passage is provided, and a heating device is arranged on the inner space of the frame base, and a clamp is placed on the clamp. When in use, the periphery can be placed in the accommodation space of the frame base. Of air and nitrogen Industry, will be completely excluded, while, by heat, filling the glass substrate on the spacer, and thus remain in the state. A liquid crystal panel is manufactured by sandwiching a high-temperature-resistant spacer, which can be protected by the spacer without the effect of the glass substrate being uniformly heated due to local overheating. A device for manufacturing a liquid crystal panel is applied to a glass substrate in a seat that extends inwardly and is inclined.

In this way, not only the vacuum state of the panel can be broken, but also the moisture in the panel can be completely eliminated. The clamp 60, which holds the elastic membrane 70, is moved upward, and then the panel in the fixture 50 is taken out to perform the liquid crystal filling operation (because it is the same as the conventional liquid crystal filling operation and is not the method to be protected in this case). So, I wo n’t repeat them here.). After the panel is filled with liquid crystal, the panel is returned to the fixture 50 (as shown in the third picture), and the fixture 60 is lowered on the fixture 50 at the same time, and then the vacuum operation is performed to make the fixture in the fixture. The elastic diaphragm 7 0 on 50 can be tightly abutted on the glass substrate 10 adjacent to it by the negative pressure generated when the vacuum is applied, and continuously pressed on the panel to The excess liquid crystal in the panel can be discharged from the gaps (not shown in the figure) that are not sealed by the gel 30 on the periphery, and the upper and lower glass substrates 10 and 20 can be bulged outward by being squeezed by the liquid crystal. The diaphragm 70 is pressurized and flatly affixed to the spacer 40 (as shown in the fourth figure). After that, the colloid can be filled in the notch of the panel, and the colloid can be hardened by light irradiation or other methods to obtain a flat liquid crystal product.
