Abstract: An electronic device may include display pixels and a display cover layer. The display cover layer may be formed from a transparent material such as glass. The display cover layer may have a nanotextured upper surface to improve the optical and mechanical characteristics of the display cover layer. The nanotextured upper surface may include first and second different types of nanostructures. The first type of nanostructures may have a relatively low aspect ratio and a first average height. The second type of nanostructures may be elongated nanostructures with a relatively high aspect ratio and a second average height that is greater than the first average height.
