Liquid crystal alignment technology can achieve the entire substrate surface of the liquid crystal molecules relative to the substrate to form a neatly arranged and has the best angle, and there is sufficient stability. Only in this way, liquid crystal molecules will be manifested in the macro-long-range orderly. It can be said that the liquid crystal alignment technology is a necessary condition for the normal operation of liquid crystal devices.
Liquid crystal orientation technology involves the nature of the orientation layer material, the treatment method of the orientation layer surface, the interaction at the interface, is a comprehensive process. The alignment of the liquid crystal alignment layer directly affects the arrangement of liquid crystal molecules on the surface of the substrate, thus affecting the uniformity, color difference, contrast, threshold voltage, response time and viewing angle of the display.
