The AR anti-reflection optical film of pvd coating machine is mainly used in LCD displays (compared to LR anti-reflection optical films) in portable products, such as automotive displays, mobile phones, DVD players, digital cameras, digital cameras, etc. Yes. Since portable products are exposed to the outdoors for a long time (compared to household LCD TVs that are used indoors for a long time), they are greatly affected by external light. Therefore, LCD displays embedded in such products need to use better radiation resistance. Optical film, and AR type can meet this requirement.
The AR anti-reflection optical film of pvd coating machine generally has a reflectivity of less than 0.3%, and can even reach the level of 0.1%. In order to achieve a low reflectivity level, the structure of AR type optical film is more complex, including TAC substrate optical film, hard film The coating layer (Hard Coat), the AR layer (including several layers of materials with high and low refractive index), and the antifouling layer make the optical film high in cost and low in mass production.
However, it is worth noting that the use of LCD displays for different application products also requires the AR-type optical film of the pvd coating machine to have other specifications. For example, in addition to the better anti-reflection function of automotive LCD displays, because of the corresponding external environmental variables, there are many specifications. Therefore, it is necessary to consider that the optical film of pvd coating machine has the characteristics of heat resistance and moisture resistance. For example, in the general automotive product specification, the temperature adaptation range is required to fall between -40°C and 85°C. Similarly, the AR anti-reflection optical film of the pvd coating machine also needs to meet this standard.
Recently, the market demand for end products corresponding to small and medium-sized LCD panels has grown significantly, especially for PNDs that have been used outdoors for a long time. DIGITIMES estimates that the CAGR from 2006 to 2010 will be as high as 46%; The use is also due to the development of large-scale mainstream sizes, from the original 1.8 inches to 2 inches to 2.4 inches to 2.8 inches. With the continuous enlargement of the volume and area of small and medium-sized LCD panels, AR anti-reflection optical films for
pvd coating machines also have growth potential in the future.
