Curing method of alignment film

Abstract

The invention discloses an alignment film curing method. The method comprises the steps that a glass substrate is provided, alignment film coating equipment is used for coating the glass substrate with an alignment film solution; a delivery mechanism is utilized for delivering the glass substrate coated with the alignment film solution to a tunnel furnace which is in butt joint with the alignment film coating equipment in a sealed mode, the glass substrate is delivered to multiple heating plates which are arranged in a precuring heating area in the tunnel furnace in sequence to be heated for precuring; the glass substrate obtained after precuring is completed is delivered to multiple heating plates of a main curing heating area in the tunnel furnace in sequence to be heated for first stage main curing; the glass substrate obtained after first stage main curing is completed is delivered out of the tunnel furnace, put into a basket and then carried into an oven to be heated for second stage curing, and then alignment film curing is completed. According to the alignment film curing method, the product quality can be guaranteed, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal panel production, in particular to a method for curing an alignment film. Background technique [0002] In the structure of the liquid crystal display, the main function of the alignment film is to anchor the liquid crystal molecules, so that the liquid crystal molecules are arranged along the set direction and maintain a certain pre-tilt angle. The production process of the alignment film has a great influence on the display effect of the liquid crystal display and performance play a key role. [0003] In the production process of liquid crystal displays, the alignment film needs to be baked at high temperature after coating to evaporate the solvent components in the alignment film solution, so that the alignment film is solidified and bonded to the surface of the glass substrate. During this process, the setting of the curing temperature and time of the alignment film has an important in...

Problems solved by technology

However, when using an oven, it is necessary to put the glass substrate coated with the alignment liquid into a basket and transport it into the oven. Since the alignment film is easy to absorb foreign matter when it is not dry, the product is likely to be contaminated during the turnover process.
