Abstract (en)
[origin: WO2018064947A1] An anti-reflective coating comprising a topmost anti-reflective material layer comprising of sapphire or Al 2O 3, the one or more middle anti-reflective material layers, and a bottommost anti-reflective material layer deposited on top of the substrate, wherein the topmost anti-reflective material layer, the one or more middle anti-reflective material layers, and the bottommost anti-reflective material layer have alternatively higher and lower refractive indices in respect with each other. The anti-reflective coating on a substrate can form high anti-scratching.
