Abstract

The invention discloses an alignment film drying system and an alignment film drying method. The alignment film drying system is used for drying alignment liquid coated on a substrate and comprises a magnetic control tube, the alignment liquid is coated on one side, facing the magnetic control tube, of the substrate, and the magnetic control tube is used for heating the alignment liquid by means of electromagnetic waves to enable the alignment liquid to form an alignment film uniform in thickness, so that display effect of a liquid crystal display can be guaranteed.

Description

【Technical field】 [0001] The invention belongs to the technical field of liquid crystal display production, and in particular relates to an alignment film drying system and a drying method. 【Background technique】 [0002] With the continuous development of optoelectronic technology and semiconductor technology, liquid crystal displays (Liquid Crystal Display, LCD) have been widely used in various fields of society. A liquid crystal display is mainly composed of two glass substrates and a liquid crystal layer arranged between the two glass substrates. Currently, the liquid crystal display is mainly a thin film transistor (Thin Film Transistor, TFT) liquid crystal display. [0003] The manufacturing process of TF T liquid crystal display is generally divided into three steps: the production of graphics on two glass substrates; the liquid crystal is sealed between the two glass substrates to form a liquid crystal display unit (CELL); the liquid crystal display unit is assemble...
