Description

Technical Field

[0001] The utility model relates to the field of display technology, in particular to a liquid crystal panel alignment device. Background Art

[0002] With the development of display technology, flat display devices such as liquid crystal displays (LCD) have been widely used due to their advantages such as thin body and no radiation, and have become the mainstream in display devices; the liquid crystal target substrate is generally composed of an array substrate, a color filter substrate and a liquid crystal molecule layer sandwiched between the array substrate and the color filter substrate. By applying a driving voltage between the array substrate and the color filter substrate, the liquid crystal molecules can be controlled to rotate, so that the light of the backlight module is refracted to produce a picture.

[0003] At present, the existing photo-alignment light source system is designed to perform exposure operations by combining a set of exposure machines with a substrate platform. An ultraviolet light source is used to irradiate an alignment film on a substrate, causing the polymer structure on the surface of the film to undergo uneven photopolymerization, isomerization or cracking reactions, inducing the chemical bond structure on the surface of the film to produce a special directionality, so as to further induce the liquid crystal molecules to align in a forward direction, thereby achieving the purpose of photo-alignment. Among them, when the glass substrate is irradiated by the ultraviolet light source, a temperature difference will be generated between the platform solid area and the hollow area of ​​the substrate platform, thereby affecting the angle of deflection of the liquid crystal, visually producing a light and dark deviation, and then causing the problem of white spots and stains on the target substrate.
