Optical alignment processing method, optical alignment mask and optical alignment mask group

Abstract

The invention discloses an optical alignment processing method, an optical alignment mask and an optical alignment mask group. The optical alignment processing method comprises the following steps of:forming an alignment film layer on the surface of a mother board of a glass substrate; arranging a multi-model group products containing different alignment direction requirements on the mother boardof the glass substrate; performing light alignment illumination after the optical alignment masks provided with different light leakage regions and light shielding regions are respectively covered onthe multi-model group products. According to the optical alignment processing method, the optical alignment mask and the optical alignment mask group, the alignment of the multi-model group productswith multiple alignment directions can be realized, and the placement position of the multi-model group products can be arbitrarily adjusted.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to a photo-alignment processing method, a photo-alignment mask plate and a photo-alignment mask plate set. Background technique [0002] With the development of display technology, various display products appear, such as LCD (Liquid Crystal Display, liquid crystal display) and OLED (Organic Light Emitting Diode, organic light emitting diode) displays. [0003] At present, LCD has been widely used in various electronic products. The main components of the liquid crystal panel include an array substrate, a color filter substrate, and a liquid crystal layer located between the array substrate and the color filter substrate. Alignment films are arranged on both sides of the liquid crystal layer. The alignment film is used to make liquid crystal molecules produce initial alignment. The alignment technology in the prior art generally uses a rubbing (Rubbing) alignment method...

AI Technical Summary

Problems solved by technology

[0004] but, figure 1 In the prior art solution shown, the alignment effect in the same direction can only be achieved when the same glass substrate mother board is subjected to photo-alignment treatment under the irradiation condition of a light source; figure 2 The existing technical solution shown is limited by the fixed shape and fixed moving direction of the visor, the multi-model group design method is still limited, and the typesetting space may not be fully utilized.

[0005] Therefore, the optical alignment method of the prior art still has defects when dealing with the alignment of multi-model group products with multiple alignment direction requirements
