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 invention relates to a method for aligning hydrogen ion beams, in particular to a method for applying hydrogen ion beams to align 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. There are many known patent documents disclosing related technologies, such as U.S. Patent No. 4153529 "causing uniform alignment of liquid crystal materials applied in 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, mainly applied to inorganic alignment films (including carbon), and the thickness of the alignment film is 100-5000A. The ion beam energy is 1-3keV. [0003] Also, such as U.S. Patent No. 6020946 "Dry processing for liquid-crystal displays using low energy ion bombardment", which is the applicatio...

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
