What is optical coating material?

There are many causes affecting the transmittance of a plane lens by optical coating. The roughness of the mirror will cause the diffuse of incident light and reduce the transmittance of the lens. In addition, the optical absorption and rotation of the material will also cause the dissipation of part of the frequency of some incident light sources. For example, materials that absorb red light will appear green. However, these factors of poor processing can be removed as far as possible.

In view of the existing LCD panel industry, whether TFT-LCD or AMOLED, substrate glass is an important material for its production.Depending on display technology, device structure and application scenario, additional single or multiple layers of glass may be required.Therefore, substrate glass is an important component of LIQUID crystal display devices and one of the key basic materials of liquid crystal display industry. Substrate glass accounts for about 4% of the production cost of liquid crystal display devices.

Now the mainstream market demand is MORE than G5 generation of substrate glass, generally speaking: G5=1 100 mm×1 300 mm;G6=1 500 mm×1 850 mm;G8.5=2 200 mm×2 500 mm.G5 substrate glass is mainly used for mobile phone, tablet computer and other mobile terminal equipment, G6 substrate glass is mainly used to produce notebook or display LCD screen, and G8.5 substrate glass is mainly used to cut large size LCD TV display screen.Compared with the low generation below G6, the substrate glass of high generation above G8.5 can effectively improve the yield and yield of large screen LCD panel, and reduce the production cost at the same time, so as to conform to the development trend of the future large screen and multi-screen era, and the market demand for high generation substrate glass of G8.5 and above will increase day by day.
