Abstract
The invention provides an alignment film coating device and an alignment film coating method, wherein a substrate is arranged on a carrying platform; a supply part is used for continuously supplying alignment liquid to an ink containing platform when coating of an alignment film is carried out; the ink containing platform is used for storing the alignment liquid, and transmitting the alignment liquid to an alignment template; the alignment template is arranged at one side of the ink containing platform away from a stretchable part; the alignment template and the substrate are oppositely arranged; one end of the stretchable part is connected with a support part; the support part is used for supporting the stretchable part; the other end of the stretchable part is connected with the ink containing platform; and the stretchable part is used for adjusting the height of the ink containing platform. According to the scheme, when coating of the alignment film is carried out, the alignment liquid is continuously supplied to the ink containing platform through the supply part; coating of the alignment film is continuously carried out; and the coating efficiency of the alignment film is increased.
Description
technical field [0001] The invention relates to the field of display technology, in particular to an alignment film coating device. Background technique [0002] The maturity of liquid crystal display (Liquid Crystal Display, LCD) technology has promoted the rapid development of electronic devices such as smart phones and tablet computers. [0003] In a liquid crystal display, an alignment film can guide the alignment direction of liquid crystal molecules. The manufacturing process of the existing alignment film is as follows: first, the printing plate of the alignment film is fixed on the roller, and then the alignment film is printed on the glass substrate through the roller. Every time the roller finishes printing the alignment film, it needs to return to the location of the alignment liquid replenishment device to replenish the alignment liquid, resulting in a decrease in the coating efficiency of the alignment film. [0004] Therefore, it is necessary to provide an al...
