设计制备了一种抗紫外(UV)辐射的塑料显示面板的减反射膜。对常用的聚碳酸酯(PC)塑料面板，在垂直入射时，减反膜紫外波段300~380 nm的平均反射率大于99.5%，可见光波段420~750 nm的残余反射率为0.22%；在45°入射时，紫外波段300~360 nm的平均反射率大于98.8%，可见光波段400~700 nm的残余反射率约为0.71%。讨论了PC基板与薄膜的附着力及应力。实验表明，PC塑料显示面板的抗UV辐射性能、减反射性能、使用的角度以及膜层的牢固度均能满足实用要求。

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.
