Embodiment 1

[0049] Such as figure 2 As shown, this embodiment provides a method for fabricating an alignment film, which is used to fabricate an alignment film on a substrate, including the following steps:

[0050] S201, forming an alignment material film layer on the substrate;

[0051] In this step, a film layer of an alignment material can be coated on the substrate to prepare for the preparation of an alignment film with alignment capability; in this embodiment, the alignment material can be a high molecular polymer;

[0052] Preferably, the substrate in this embodiment may be an array substrate, or may also be a color filter substrate; when an alignment film is formed on the array substrate, since the array substrate includes: a pixel electrode layer, which is used to form a plurality of comb-shaped structures Pixel electrode (ITO Slit), so S201 can specifically include:

[0053] An alignment material film layer is formed on the pixel electrode layer.

[0054] Such as image 3 As...

Embodiment 2

[0081] This embodiment provides a manufacturing system for an alignment film, which is used to form an alignment film on a substrate, such as Image 6 shown, including:

[0082] The carrying platform 601 movable in the horizontal direction is used to carry the substrate 602 formed with the alignment material film layer 603, and drives the substrate 602 to move in the horizontal direction;

[0083] In this embodiment, the substrate 602 may be an array substrate or a color filter substrate, taking the array substrate as an example, Image 6 The middle array substrate 602 includes: a pixel electrode 602b and a substrate film layer 602a; wherein the substrate film layer is composed of a substrate substrate, a metal layer and a film layer;

[0084] A light irradiator 604, located above the carrying platform 601, is used to emit line polarized ultraviolet light to irradiate the alignment material film layer 603 moving in the horizontal direction, so as to form an alignment film wit...

Abstract

The invention provides a manufacture method and system for an alignment film. The manufacture method comprises the steps that an alignment material film layer is formed on a substrate; the substrate is placed on a bearing table which can move in the horizontal direction, so that the substrate can move along with the bearing table in the horizontal direction in the alignment process; a first irradiation angle of light ray irradiation on the alignment material film layer is determined, the first irradiation angle is a first included angle between an irradiating light ray and the substrate, and the first included angle is an acute angle; the bearing table is triggered to move in the horizontal direction, and linearly polarized ultraviolet light is utilized to irradiate the alignment material film layer according to the first irradiation angle to form the alignment film with an alignment function. According to the manufacture method, the alignment film with the alignment function is manufacture by irradiating the alignment material film layer in the direction which is not vertical to the substrate with the linearly polarized ultraviolet light, therefore, the incident light and the reflected light do not interfere with each other, and the uniformity of the alignment function of the alignment film is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of liquid crystal displays, in particular to a method and system for manufacturing an alignment film. 【Background technique】 [0002] TFT LCD (Thin Film Transistor Liquid Crystal Display) technology has become the mainstream technology of liquid crystal display. At present, the most widely used alignment technology in TFT LCD production is rubbing alignment technology, which can provide strong alignment ability of liquid crystal molecules; but in the process of brushing, due to the use of flannelette contact friction, static electricity and particles ( particle) causes damage to the liquid crystal element, which leads to poor picture quality such as various MURA. [0003] In order to improve the quality and yield of LCD screens, many panel manufacturers use non-contact alignment methods to make alignment films. At present, the non-contact alignment methods are mainly photo-alignment technology; among them...
