Abstract

The invention relates to a liquid crystal spraying device used for improving the efficiency of liquid crystal dripping. The liquid crystal spraying device contains a dripping device and a spray head. The dripping device is provided with a distribution pipe which is used for conveying liquid crystal materials. The spray head is installed on the bottom of the dripping device and connected the distribution pipe, and is provided with a plurality of spraying flow channels, wherein, each spraying flow channel is respectively and directly communicated to the distribution pipe. By the invention, the technical efficiency of the liquid crystal dripping technique can be greatly improved. Besides, as the invention utilizes non-bending straight spraying flow channels for spraying liquid crystal drops, the liquid crystal materials are not easy to be blocked at the bending point and can be evenly distributed to each spraying flow channel, and the phenomenon that the sizes of the sprayed liquid crystal drops are different, which is caused by the excess difference.of the shape and the length of the all the spraying flow channels, is not easy to occur.

Description

technical field [0001] The invention relates to a liquid crystal spraying device, in particular to a liquid crystal spraying device which uses a spraying head to drop a plurality of liquid crystal drops at a time. Background technique [0002] The liquid crystal display panel includes a color filter substrate (color filter substrate, CF substrate), a thin-film transistor substrate (thin-film transistor substrate, TFT substrate), and a layer of liquid crystal molecules filled between the CF substrate and the TFT substrate. The liquid crystal display panel can be roughly divided into two types according to the filling method of liquid crystal molecules: vacuum injection and one drop fill (ODF). Vacuum injection refers to bonding the CF substrate and the TFT substrate first and leaving a small hole on the side of the CF substrate and the TFT substrate, and then using the capillary principle to slowly inject liquid crystal molecules between the CF substrate and the TFT substrate...
