Method for hydrogen ion beam applying to liquid crystal molecule distributing direction

Abstract

The disclosed method is in use for solving issues of physical destroy caused by using current argon ion direction configuring, and degraded surface of direction configuring film. Using ion beam of containing hydrogen to impact direction configuring film directly, the invention reduces physical destroy, and carries out chemical reaction with direction configuring film to optimize direction configuring quality.

Description

Technical field [0001] The present invention is a method for aligning a hydrogen ion beam, in particular to a method for applying a hydrogen ion beam to the alignment of liquid crystal molecules. Background technique [0002] Traditional liquid crystal molecular alignment uses argon (Ar) ion beams to achieve the alignment effect of the alignment layer. Many patent documents are known to disclose related technologies, such as US Patent No. 4153529 "Causes the alignment of liquid crystal materials to be applied uniformly and parallel to liquid crystal cells. Means and method for inducing uniform parallel alignment of liquid crystal material in a liquid crystal cell" is the earliest patent for ion beam alignment. The main application is inorganic alignment film (including carbon), and the alignment film thickness is 100-5000A. The ion beam energy is 1-3keV. [0003] Also, for example, US Patent No. 6020946 "Dry processing for liquid-crystal displays using low enefgy ionbombardment",...

AI Technical Summary

Problems solved by technology

[0009] However, in the above-mentioned patent documents on the use of argon ion beam alignment, because the argon ion beam has no chemical reactivity and the particle size is too large, it will cause serious physical damage, thereby deteriorating the surface of the alignment film, affecting the electrical characteristics of the alignment film, and easily causing Problems such as flicker and image sticking
