Embodiment Construction

[0029] see Figure 4 to Figure 6 , Figure 4 A schematic diagram of the ODF process for a preferred embodiment of the liquid crystal coating device of the present invention, Figure 5 It is the substrate coated by the ODF process, Image 6 It is a schematic cross-sectional view of a liquid crystal dropper. The preferred embodiment of this liquid crystal coating device comprises a plurality of densely arranged liquid crystal droppers 22, and a shield 23 made of transparent material, and other conventional components such as liquid crystal containers can adopt conventional configurations, which will not be repeated here; The caliber of the guide tube 221 inside the liquid crystal dropper 22 for the liquid crystal to flow becomes larger on the liquid crystal outflow side, and the liquid crystal dropper 22 has a heating device 222 for heating the liquid crystal flowing through to control the temperature of the liquid crystal flowing out. Figure 4 It shows the situation that th...

Abstract

The invention relates to a liquid crystal coating device. The liquid crystal coating device comprises a plurality of liquid crystal drippers which are densely arrayed, wherein the diameter of a flow guide pipe through which a liquid crystal flows in each liquid crystal dripper is increased on a liquid crystal flowing-out side; and each liquid crystal dripper is provided with a heating device for heating the flowing liquid crystal to control the temperature of the flowing liquid crystal. The liquid crystal coating device provided by the invention can realize a manner of coating the liquid crystal in a plane, and a Drop mura bad condition can be avoided; the dripping speed of a single liquid crystal is improved; and the liquid crystal coating device is very helpful for improving the yield of products, shortening the manufacturing time of the products and improving the competitiveness of the products.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal coating device. Background technique [0002] The production of TFT (Thin Film Transistor) display devices is very complicated. It needs to go through the production of array substrates, the production of color filter substrates, the addition of liquid crystals on the array substrates, the coating of frame glue on the color filter substrates, and the completion of the above processes on the array substrates. It is combined with the color filter substrate, and the entire production of the TFT display device is completed through processes such as curing and cutting. There is a process in the production process: the process of dropping liquid crystals on the array substrate or color filter substrate, referred to as: ODF (drop-in injection) process or filling process. [0003] At present, the industry basically adopts ODF technology, that is, a single...
