After three years of scientific and technological research, China's optical thin-film precision microdisplay technology made a major breakthrough in the successful break the monopoly of foreign technology.This is the reporter on the 10th from the Hubei Provincial Defense Science and Industry Office and the Hubei Aerospace Chemical Technology Institute obtained the news.According to reports, optical Film precision microreplication is the technique of precisely coating the surface of an optical film substrate with a specially formulated resin and then forming it on an engraving roll having a specific design nanoscale geometry.
It is widely used in LCD flat panel display backlight module brightness enhancement film and diffusion film, road traffic signs micro-prism reflective film, liquid crystal display protection with anti-reflection film and anti-reflection film, naked eye 3D display film and home appliances with imitation brushed metal high gloss film Etc. The added value of these products, the market demand, the key technology has been in the hands of foreign companies.
From 2014 to 2016, Hubei Aerospace Chemical Technology Research Institute undertook the key technology development and application of 'Major Technology of Optical Membrane Precision Microdrawing Technology' in Hubei Province, and conducted research on structural design, engraving resin formulation and coating technology successively. Recently, Through the Science and Technology Hall in Hubei Province acceptance.
The relevant person in charge of Hubei Institute of Aerospace Chemical Technology said that they designed a special surface coating microstructure, developed a special carved coating resin formulations, in the back of the optical film marking coating with anti-glare, anti-scratch or anti-static treatment to improve Product yield 20% or more, which greatly improved China's new material industry chain science and technology level.
According to reports, at present, this technology has been applied in important national defense projects, reporting 10 invention patents.
