Photo-alignment equipment

Abstract

The invention provides photo-alignment equipment which comprises a machine used for conveying a to-be-aligned substrate. An alignment light source, polaroid and a twisted nematic liquid crystal box used for adjusting the alignment light polarization direction are arranged above the machine, the photo-alignment equipment has the advantages that compared with existing photo-alignment equipment, the alignment light polarization direction can be adjusted according to the alignment requirement, and therefore alignment films with different alignment requirements can be aligned without rotating the substrate; the technical problems that for the photo-alignment equipment in the prior art, the compatibility is weak, the alignment light cannot be adjusted, when substrates with different alignment requirements enter the equipment, the substrates need to be rotated by 90 degrees to enter the equipment with the long edges, the number of machines and the sizes of all parts need to be increased to meet the light alignment of the substrate, and the equipment cost is increased are solved.

Description

technical field [0001] The invention relates to the technical field of optical alignment of liquid crystal display panels, in particular to an optical alignment device. Background technique [0002] Most of the existing liquid crystal displays are backlight liquid crystal displays, which include a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. Generally, a liquid crystal panel is composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) filled between the two substrates. Its working principle is to control the rotation of the liquid crystal molecules in the liquid crystal layer by applying a driving voltage on the CF substrate and the TFT substrate, control the output of light, and refract the light from the backlight module to produce a picture. [0003] In the manufact...

Problems solved by technology

[0006] The invention provides an optical alignment device, which can align the alignment films of different types of liquid crystal display panels without changing the size of each component, so as to solve the need to rotate the substrate before the substrates with different alignment requirements enter the alignment device , when the substrate enters with the long side, it is necessary to increase the size of the machine and each component, thereby increasing the technical problem of equipment cost
