Abstract

The invention discloses a method for processing an orientation layer of a liquid crystal display. By means of the method, a tip surface is used for pressing the orientation layer to form a groove. The method at least includes the following steps: coating an orientation agent on a substrate; performing drying processing to obtain the orientation layer; and using the tip surface to press the orientation layer to form the groove on the orientation layer. The invention further discloses a device for processing the orientation layer of the liquid crystal display. The device at least comprises a pressing body, wherein more than one pressing protrusion is arranged on the pressing body, and more than one groove is formed on the pressing surface. The device further comprises a shifting unit and a support table placed on the substrate, and the shifting unit is connected onto the pressing body or the support table. The pressing body is plate-shaped or cylindrical, when the pressing body is cylindrical, the pressing protrusion is axially parallel to the pressing body, and a support shaft is arranged at the axis position of the pressing body.

Description

technical field [0001] The invention relates to a processing method and device for an alignment layer of a liquid crystal display screen. Background technique [0002] Liquid crystal display technology has been applied to various liquid crystal display terminal equipment such as liquid crystal TV, liquid crystal display, tablet computer and mobile phone, and liquid crystal alignment technology plays an important role in liquid crystal display technology. The liquid crystal alignment technology can make the liquid crystal molecules on the surface of the substrate form an orderly arrangement, so that the liquid crystal molecules have sufficient stability and show a long-range ordered state macroscopically. [0003] The liquid crystal alignment technology is mainly the rubbing alignment technology widely used in the liquid crystal display field. At present, the rubbing alignment technology widely used in the field of liquid crystal display is to use fiber or nylon and other ma...
