Embodiment Construction

[0022] Please refer to Figure 2a to Figure 2c , which is a schematic diagram of the first embodiment of the liquid crystal filling method of the present invention, the steps are as follows, firstly, a carrying platform 240 is provided. A first substrate 210 is placed on the carrying platform 240, wherein the first substrate 210 has a liquid crystal filling region 220, and the liquid crystal filling region 220 has a first edge 221, a second edge 222 and two sides Side 223. The liquid crystal filling area 220 also has a buffer area A. As shown in FIG. A certain amount of liquid crystal 230 is dropped on the liquid crystal filling area 220 at a position of a buffer interval H from the buffer zone A near the first edge 221 . Such as Figure 2b As shown, the position of the air knife 270 is fixed, and the carrier table 240 carries the first substrate 210 and moves along a first direction D1, and the liquid crystal 230 is moved from the first edge 221 to the second edge by the w...

Abstract

The invention provides a liquid crystal filling method which comprises the following steps of: providing a bearing table; placing a baseplate with a liquid crystal filling area on the bearing table, wherein the liquid crystal filling area is also provided with a buffer area; dripping liquid crystals into the liquid crystal filling area; and utilizing a wind cutter to enable the liquid crystals of the liquid crystal filling area to diffuse along one direction.

Description

technical field [0001] The invention relates to a method for filling liquid crystals, in particular to a method for filling liquid crystals by using an air knife to diffuse and fill them. Background technique [0002] Please refer to Figure 1a , a schematic diagram of a traditional liquid crystal filling method on a substrate; firstly, a first substrate 110 is provided, and then a certain amount of liquid crystal 130 is dropped and evenly distributed on each position of the first substrate 110 . A second substrate 120 is provided, and a sealant 121 is coated around the second substrate 120 . The area surrounded by the sealant 121 is larger than the above-mentioned positions where the liquid crystals 130 are distributed on the first substrate 110 . After the liquid crystal 130 dropped on the first substrate 110 diffuses for a period of time, the first substrate 110 and the second substrate 120 or panels are assembled. Next, an ultraviolet (UV) light L is applied to the ass...
