An alignment device and method for an air-floating liquid crystal substrate

Abstract

The embodiment of the present invention discloses an alignment device for an air-floating liquid crystal substrate, which includes: a heating platform, on which a plurality of air holes are arranged, and the air holes are used to deliver hot air with a uniform temperature and vertically upward; a support frame, which is arranged on the The surroundings of the heating platform are used to support and clamp the liquid crystal substrate to be aligned; the supporting thimbles are evenly arranged in the heating platform, which can move up and down in the same direction as the support frame, and are used to support the liquid crystal substrate at least part of the time. The bottom of the liquid crystal substrate; wherein, the air injection volume of the air hole gradually decreases from the center of the heating platform to the edge of the heating platform. The embodiment of the invention also discloses a corresponding alignment method. According to the embodiments of the present invention, the liquid crystal substrate can be evenly heated and irradiated with ultraviolet light during the alignment process, and the quality and product yield of the liquid crystal substrate can be improved.

Description

technical field [0001] The invention relates to a thin film transistor liquid crystal display (Thin Film Transistor liquid crystal display, TFT-LCD) manufacturing technology, in particular to an alignment device and method for an air-floating liquid crystal substrate. Background technique [0002] Among the existing liquid crystal display manufacturing technologies, ultraviolet curing (UV Curing) is an important process. After the liquid crystal substrate is filled with liquid crystal mixture, it needs to complete the alignment process of liquid crystal under the combined action of ultraviolet light and electric field. [0003] The principle of alignment by ultraviolet curing is to apply an electric field on the upper and lower sides of the liquid crystal substrate, and irradiate the liquid crystal with ultraviolet light, so that the reactive monomers in the liquid crystal move up and down under the action of the electric field, and polymerize under the action of ultraviolet ...

AI Technical Summary

Problems solved by technology

This can reduce the contact time between the thimble 91 and the liquid crystal substrate 1 at the same position. Since the thimble 91 and the liquid crystal substrate 1 inevitably need to be in contact, this existing technology can only reduce the occurrence of uneven alignment, but cannot completely avoid it. The emergence of non-uniform alignment

[0008] To sum up, in the existing technology, when aligning the liquid crystal substrate, the occurrence of uneven alignment cannot be avoided, so how to improve the quality and product yield of the liquid crystal substrate is a problem that needs to be solved
