Anti-ultraviolet radiation of antireflection coatings on display plastics is presented. For polycarbonate (PC) substrate which is one of the commonly used plastics, the calculated average reflectance at normal incidence in ultraviolet region of 300~380 nm is greater than 99.5% and the residual reflectance in visible region of 420~750 nm is 0.22%. The reflectance at 45° incidence in ultraviolet region of 300~360 nm is greater than 98.5% and that in visible region of 400~700 nm is 0.71%. The adhesion and stress of coatings on plastics are discussed. It is proved by experimental results that all of the properties, e.g., the anti-ultraviolet radiation, the antireflection, the wide incident angle and the durability of the coatings on plastics can be used for practical display applicaitons.
