Problems solved by technology

But because existing liquid crystal coating device can only be coated with rectangular pattern, therefore, the contriver finds, if the area of ​​this small rectangle is less then the substrate can't be fully coated with the small rectangle added on substrate; If the area is large, it will contaminate the sealant on the peripheral area of ​​the substrate, resulting in poor sealing of the substrate

Embodiment 1

[0032] combine image 3 and Figure 4 As shown, the present embodiment provides a liquid crystal coating nozzle, which includes a nozzle body 1, and the nozzle essentially has a plurality of drop holes 10 for coating liquid crystal; wherein, a plurality of drop holes 10 form a plurality of Coating area 11, and at least two coating areas 11 have different shapes; the liquid crystal coating nozzle also includes at least one switch control unit 5; each of the switch control units 5 is used to control at least one of the coating Each of said orifices 10 in area 11 is either open or closed.

[0033] Because in the coating area 11 that the drip hole 10 of the liquid crystal coating nozzle of the present embodiment is formed, the shape of at least two coating areas 11 is different, so adopting the liquid crystal coating nozzle of the present embodiment to coat on the substrate Different graphics can be applied to liquid crystals. Specifically, taking the shape of the coating area ...

Abstract

The invention provides a liquid crystal coating nozzle and a liquid crystal coating device and belongs to the technical field of liquid crystal coating. The problem that the existing liquid crystal coating device is incapable of meeting the requirements of the liquid crystal coating technology can be solved. The liquid crystal coating nozzle comprises a nozzle body and at least one switching control unit; multiple drip holes used for liquid crystal coating are arranged in the nozzle body and form multiple coating areas, and at least two of the coating areas are of different shapes; each switching control unit is used for controlling each drip hole in the coating areas to be opened or closed. The liquid crystal coating nozzle can satisfy diversity of the liquid crystal coating technology.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal coating, and in particular relates to a liquid crystal coating nozzle and a liquid crystal coating device. Background technique [0002] Liquid crystal displays have been widely used in various electronic products, and most of them are backlit liquid crystal displays, which are composed of a liquid crystal panel and a backlight module. Wherein, the liquid crystal panel generally consists of an array substrate and a color filter substrate, and a liquid crystal layer is sealed between the array substrate and the color filter substrate. [0003] During the assembly process of the liquid crystal panel, the liquid crystal is filled and sealed between the array substrate and the color filter substrate. In the prior art, liquid crystals are usually sprayed on an array substrate or a color filter substrate (hereinafter referred to as the substrate) coated with a sealant by means of inkjet printing...
