Problems solved by technology

When the alignment film 110 has poor cleanliness or foreign matter on the substrate 100, there will be defects such as uneven film thickness, and then many defects 111 will be generated in the alignment film 110 at these positions.
[0006] However, in the aforementioned method, the method of first removing the alignment film and then reapplying it takes a lot of time, and causes more material and energy loss or waste, which increases the cost and reduces the printing yield.

Embodiment Construction

[0040] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are exemplified below and described in detail with accompanying drawings.

[0041] The alignment film repair method proposed by the present invention is used in the manufacture of liquid crystal display panels. The steps of the alignment film repair method include: first, providing a substrate, and forming a first alignment film on one surface thereof, the first alignment film has a defect. Then, a liquid drop of an alignment liquid is dropped on the defect.

[0042] The method for repairing the alignment film according to a preferred embodiment of the present invention may further include performing a pre-treatment before dropping the alignment liquid onto the defect. The pretreatment is carried out by laser irradiation or UV irradiation.

[0043] The aforementioned method for repairing the alignment film in a preferred embodiment ...

Abstract

The invention relates to a method for repairing alignment films, which is used for manufacturing liquid crystal display panels and comprises the following steps: firstly, providing a base plate, and forming a first alignment film with a defect on the surface of the base plate; then, dripping drops of an alignment liquid into the defect, or forming a second alignment film on the surface of the first alignment film.

Description

technical field [0001] The invention relates to a method for repairing an alignment film, in particular to a method for repairing an alignment film suitable for a liquid crystal display panel. Background technique [0002] In recent years, the development of flat-panel displays has become increasingly mature, and its lightness, lightness and convenience are popular among consumers. Therefore, the mass production process of flat-panel displays is an urgently needed technology in the current market. As far as the manufacture of thin film transistor liquid crystal display (TFT-LCD) is concerned, it can be roughly divided into three major processes. The first stage is the process of thin film transistor substrate and color filter substrate, and the second stage is alignment, liquid crystal filling, sealing, The panel assembly process of laminating the polarizer; the third part is the liquid crystal display module process of backlight module and panel assembly. The alignment pro...
