Problems solved by technology

Using light or heat source for surface treatment supplemented by brushing alignment will have problems with electrical characteristics such as high residual DC voltage or poor thermal stability
The known technology of using light to treat the surface of the alignment film cannot accurately produce the required characteristics of the alignment film, because it is not easy to control the dose of light, so that the surface of the alignment film will be damaged due to exposure, or it is necessary to use a specially designed Alignment films, etc., cannot achieve a stable high pretilt angle state

Embodiment Construction

[0036] The present invention is a method for controlling the pretilt angle of liquid crystal molecules. In view of the fact that the pretilt angle of liquid crystal molecules in a liquid crystal display is related to the density of side chains (side chains) on the surface of an alignment film, the precisely adjustable plasma (plasma) or The particle beam generated by ions treats the surface of the alignment film of the liquid crystal display device, thereby adjusting the density of side chains on the surface of the alignment film, thereby changing the pretilt angle of the liquid crystal molecules. Moreover, unlike the known technology that needs to specially prepare and mix vertical and horizontal alignment films to achieve a higher pretilt angle, the present invention only requires a single vertical alignment film (including its materials and alignment film solution), and then applies the following detailed description The required surface treatment and alignment methods can a...

Abstract

The invention discloses a making technique of LCD component, which comprises the following parts: two bases, two layers of vertically mated film at certain face of base, two face-to-face side-direction films, a layer of liquid crystal layer between two face-to-face side-direction films. The invention can be LCD panel structure of Optically Compensated Birefrigence (OCB), which makes the pre-incidence scale of vertical side-direction film surface between 20 deg and 80 deg in the particle processing LCD component making course generated by plasma or ion beam.

Description

technical field [0001] The invention relates to a liquid crystal display component manufacturing technology, which uses particles produced by plasma or ion beams to carry out surface treatment on the vertical alignment film in the liquid crystal display structure before the alignment process to control the pretilt angle of liquid crystal molecules to achieve The purpose of an optically compensated birefringence alignment (Optically Compensated Birefrigence, OCB) liquid crystal panel structure with adjustable pretilt angle. Background technique [0002] Liquid crystal (Liquid Crystal) can be used as a display due to its unique photoelectric properties. Generally, the mass-produced flat liquid crystal display (LCD) is mainly TN (Twisted Nematic) type. [0003] The basic structure of the TN-type liquid crystal display is two upper and lower conductive glass substrates, in which Nematic liquid crystal is injected, and a polarizing plate with polarization directions perpendicular...
