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
The present invention particularly utilizes air knife to make the method for liquid crystal diffusion filling about a kind of method of filling liquid crystal.
Background technology
Please refer to Fig. 1 a, its traditional liquid crystal is filled in the method synoptic diagram of substrate; At first, provide one first substrate 110, drip certain amount of liquid crystal 130 again and be evenly distributed on first substrate, 110 each positions.One second substrate 120 is provided, and is coated with frame glue 121 all around at second substrate 120.121 area surrounded of frame glue are distributed in the position of first substrate 110 greater than above-mentioned liquid crystal 130.Wait to drip after the liquid crystal 130 of first substrate 110 spreads a period of times upright first substrate 110 of group and second substrate 120 or group facade plate.Then, first substrate 110 and second substrate 120 that will organize again after standing bestowed a ultraviolet (UV) illumination L.UV illumination L will make 121 sclerosis of glue frame cemented, and then make first substrate 110 and second substrate 120 stick together fixing mutually.
Yet the method that this traditional liquid crystal is filled in substrate will produce some disappearances.Please refer to Fig. 1 b, it is the synoptic diagram after traditional first substrate and second substrate in batch are stood.Because traditional liquid crystal 130 is filled in the method that first substrate 110 utilizes liquid crystal 130 to distribute and drip.The method can't guarantee that liquid crystal 130 can completely be evenly distributed in first substrate 110 through after one period diffusion time.Therefore in the upright stage of group, can find that second substrate 120 will produce the suitable situation of air spots because of spreading uneven liquid crystal 130.Particularly,, may spread deficiency because of liquid crystal because distance center point is far away near the liquid crystal 130 around the glue frame 121, and sept (Spacer) anchorage force deficiency, cause the peripheral region to cause and cave in.Therefore, the peripheral region has one section height fall compared to central area and central area, thus the situation that causes second substrate, 120 central areas protuberance and peripheral region to sink, and then influence panel uniformity and display quality.
Summary of the invention
The object of the present invention is to provide a kind of method of filling liquid crystal, the peripheral region has one section height fall compared to central area and central area in the prior art to solve, so cause second substrate center zone protuberance and the sagging situation in peripheral region, and then influence the technical matters of panel uniformity and display quality.
The step of liquid crystal filling method of the present invention is as described below: at first, provide a plummer.One first substrate is placed on the plummer, and wherein first substrate has a liquid crystal fill area, and the liquid crystal fill area has one first ora terminalis, one second ora terminalis and dual side-edge, has a buffer zone in the liquid crystal fill area again.Certain amount of liquid crystal is dripped in liquid crystal fill area and the distance position by buffer zone one buffer space of first ora terminalis.Plummer is carrying first substrate and is moving along a first direction, utilizes the blast of an air knife (wind cutter) that liquid crystal is spread diffusion by first ora terminalis toward the second ora terminalis direction.When air knife when finishing diffusion process, the diffusion zone of liquid crystal has identical buffer space with first ora terminalis, second ora terminalis and the dual side-edge of liquid crystal fill area.
Because the blast of air knife spreads diffusion with the average past same direction of liquid crystal, so the liquid crystal fill area that liquid crystal is distributed on first substrate is quite average.And liquid crystal central area and peripheral region can't produce height fall.Therefore, organize immediately, can't produce the difference on second substrate height, so can solve the disappearance of conventional practice when one second substrate and first substrate that are coated with the glue frame.
