Abstract

The invention relates to the technical field of display device film forming processes, in particular to a coating method of alignment liquid and a preparation method of an array substrate. The coating method comprises the following steps that a substrate is provided, a pre-coating area on the surface of the substrate is divided into a first coating area and a second coating area which are adjacent, the first coating area comprises an effective display area and a first peripheral area adjacent to the effective display area, and the second coating area comprises a second peripheral area adjacent to the effective display area; wherein the second peripheral area is adjacent to the binding area, and the first peripheral area is not adjacent to the binding area; and firstly coating the alignment liquid on the first coating area, and then coating the alignment liquid on the second coating area. According to the coating method and the coating process, diffusion of the alignment liquid can be controlled so that the alignment liquid can not cover the binding area easily, the effective display area can be evenly covered, and the formed alignment film can reduce the light leakage phenomenon of the ears of the display panel.

Description

technical field [0001] The present application belongs to the technical field of display device film forming technology, and in particular relates to a method for coating an alignment liquid and a method for preparing an array substrate. Background technique [0002] The process of liquid crystal display panel is often divided into color filter substrate (CF, ColorFilter) process, thin film transistor array substrate (TFT, ThinFilmTransistor) process and cell (Cell) process. CF process generally involves black matrix (BM), color resistance ( R / G / B), indium tin oxide (ITO), alignment film; TFT process generally involves the first layer of metal (M1), active layer (GIN), second layer of metal (M2), protective layer (PV) , indium tin oxide (ITO), alignment film; the box-forming process generally involves a liquid crystal layer and a sealant. The box-forming process is performed after the CF substrate and the TFT substrate are paired, so the quality of the box-forming process d...
