Problems solved by technology

In the existing multi-model group (MultiModelGroup, MMG) technology, the same substrate contains multiple products with different graphics, which can reduce the number of substrates, but also makes the mask more complicated
The mask is expensive and requires high precision, and the cost of design, production, transportation, storage, replacement and installation is high, which brings a large burden to both designers and producers

Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts also fall within the protection scope of the present invention.

[0029] figure 1 is a schematic top view of the substrate of MMG products. like figure 1 As shown, multiple products are arranged on the same substrate. In this example, two columns of product 1 and two columns of product 2 are arranged on the substrate 3, and the product 1 and product 2 are arranged at intervals in the row direction. The liquid crystal molecular orientations of product 1 and...

Abstract

The embodiment of the invention provides a mask plate. The mask plate comprises a plurality of baffles, a frame body and a light transmission region. The framework is provided with a supporting part and a movable part. Each baffle is configured to the light transmission region used for shielding. The supporting part is configured to a baffle for supporting the light transmission region. The movable part is configured to move the baffles to positions for shielding the light transmission region. With the adoption of the mask plate provided by the embodiment of the invention, one mask plate can be used for producing different MMG products; in a production process, the mask plate does not need to be replaced and irradiation and orientation can be carried out; the mask plate does not need to be detached in a normal service life range; and a production process is optimized and the cost is effectively reduced.

Description

technical field [0001] The invention relates to photo-alignment technology, in particular to a mask plate and a photo-alignment method. Background technique [0002] With the development of display technology and the progress of society, liquid crystal display technology has been more and more widely used by people, and plays a vital role in industrial production and people's life. [0003] Conventional methods for making liquid crystals on a liquid crystal display panel have a pretilt angle include a contact-type rubbing (Rubbing) alignment method and a non-contact-type PhotoAlignment (PhotoAlignment) alignment method. The friction orientation method is to rub the surface of the film to be aligned with a flannelette roller, and the molecules on the surface of the film to be aligned are arranged in a specific direction by applying physical pressure. When the roller rubs against the alignment film to be aligned, dust particles and static electricity residues and other fricti...
