LCD alignment system

Abstract

The utility model discloses a liquid crystal alignment system, which is characterized in that on the surface of an alignment membrane with liquid crystal molecule array, a singular or a plurality of plasma generation devices are used to treat the alignment membrane to align the liquid crystal molecules with a pre-tilt angle. Compared with the prior art, the utility model reforms the surface of the alignment membrane through the method of adjustable direction and angle, thus achieves the stability of pre-tilt angle alignment from single fabrication process, and overcomes the disadvantages of the prior art.

Description

technical field [0001] The invention relates to a substrate surface alignment technology, in particular to a liquid crystal alignment system. Background technique [0002] With the development of network and video technology, the application of flat-panel displays has become more and more important and penetrated into people's daily life. Compared with traditional picture tube flat-screen TVs, liquid crystal displays (LCDs) have the advantages of light weight, small size, full With the advantages of color display, no radiation, digitalization, high image quality, and power saving, it has become the mainstream of the next generation of flat-panel displays. [0003] The liquid crystal display uses the electric field to control the geometric change of the liquid crystal to change the transmission path and phase of the light, and cooperates with the polarizer (Polarizer) to produce bright and dark effects, plus the cooperation of the driving circuit and the color filter (Color F...

AI Technical Summary

Problems solved by technology

However, although the results obtained by using this technology have almost reached the standard of commercially available products, since the plasma beam alignment technology uses a single plasma generation device to modify the alignment film by scanning back and forth multiple times, the manufacturing process takes a long time. Long, difficult to adjust the direction, not conducive to mass production

At the same time, the vibration generated when the plasma generating device scans back and forth will also cause instability in the manufacturing process
