1293381 V. INSTRUCTION DESCRIPTION (1) Field of the Invention Especially for a liquid crystal display This case is a liquid crystal injection method for manufacturing a liquid crystal injection method panel. BACKGROUND OF THE INVENTION In today's display industry, liquid crystal displays have gradually replaced image tube displays as mainstream products due to their low radiation and low power consumption. Referring to the first drawing, which is a cross-sectional view of a liquid crystal display panel, the upper substrate 10 and the lower substrate 11 are sealed by a gap structure 12 to form a space, and a liquid crystal 13 is injected into the space. The conventional liquid crystal injection method comprises the following steps: (1) placing a liquid crystal display panel 2 1 and a liquid crystal arc 2 2 carrying liquid crystal into a sealed chamber 20, and vacuuming the sealed chamber 20 (2) contacting the liquid crystal injection hole 2 1 1 reserved on the liquid crystal display panel 21 with the surface of the liquid crystal on the liquid crystal cell 2;

(3) Destroying the vacuum state of the sealed chamber 20, so that the liquid crystal is continuously injected into the liquid crystal display panel 21 due to the atmospheric pressure, thereby completing the liquid crystal injection operation (as shown in the second figure). In the liquid crystal display panel completed by the above liquid crystal injection method, the liquid crystal cannot be completely filled due to the vapor pressure of the small molecular substance remaining in the sealed chamber 20 (as shown in the second figure, the gap 2 3 ) Especially when manufacturing large-sized panels, the probability of this defect is relatively easy to increase, so

How to improve the above-mentioned defects is the main purpose of the development of this case. SUMMARY OF THE INVENTION The manufacture of the system is performed on a surface of a liquid crystal panel with a liquid crystal dish on a panel of a liquid crystal panel, and the surface is subjected to vacuuming and repeated according to the liquid crystal. This heating action is between. The container of the present case is filled with a liquid crystal injection, and the method comprises placing a vacuum chamber for vacuum treatment, reserving contact, and performing the concept and the concept of the concept. In order to make the liquid crystal and the use of the liquid crystal, the liquid crystal is operated by the liquid crystal. 'Liquid crystal system is 'liquid crystal liquid crystal input method, suitable for a liquid crystal display surface of the following steps: in a liquid crystal display panel, the liquid crystal fox is loaded with liquid crystal, the action; the liquid crystal carried on the liquid crystal dish The liquid crystal display injection hole and the liquid crystal carried by the liquid crystal are damaged by the vacuum state of the sealed chamber, so that the liquid crystal injection hole injects the liquid crystal into the liquid. The processing performed on the sealed chamber in the implantation method is performed by performing a heating operation on the liquid crystal m on the liquid crystal m in a polling method. The temperature of the dish in the liquid crystal dish is increased to 80 degrees Celsius to 200 degrees Celsius in the injection method.

On the other hand, it is a liquid injection method suitable for the process of applying a liquid, and the method comprises the following steps:

Page 5 1293381 V. Description of the Invention (3) The device and a liquid carrier m are placed in a closed chamber, the liquid carrier is loaded with liquid; a vacuum is applied to the sealed chamber; the liquid carrier is The liquid carried thereon is subjected to a treatment to convert a portion of the liquid into a gas; a liquid injection hole reserved in the container is brought into contact with a surface of the liquid carried by the liquid crystal; and a vacuum of the sealed chamber is destroyed. In a state, the liquid is injected into the container from the liquid injection hole by the action of atmospheric pressure, thereby completing the action of injecting the liquid into the container. According to the above concept, the vacuuming operation of the sealed chamber in the liquid injection method and the treatment of the liquid carried by the liquid bearing orphan are performed in a plurality of turns and repeatedly. According to the above concept, the treatment of the liquid carried on the liquid carrier in the liquid injection method is a heating operation of the liquid bearing. According to the above concept, in the liquid injection method, the liquid system is a liquid crystal, and the container is a liquid crystal display panel. According to the above concept, the treatment in the liquid injection method is to raise the temperature of the liquid crystal to between 80 and 200 degrees Celsius. A brief description of the case The following drawings and detailed descriptions can be used to obtain a more in-depth understanding: The first figure is a schematic diagram of the cross-sectional structure of a liquid crystal display panel. The second picture: it is a liquid crystal display panel to complete the liquid crystal injection by conventional means.
