Abstract: An electronic device may include an ambient light sensor or other semiconductor sensor. The sensor may produce signals in response to light incident on the electronic device and therefore incident on the sensor. In some cases, components within the electronic device, such as infrared components, or external light sources may interfere with the operation of the sensor. Therefore, the sensor may include a filter that transmits at least a portion of visible light while blocking infrared light. Because light may be incident on the electronic device from a variety of angles, a diffuser in the sensor may scatter the light into a desired angular distribution. To ensure that infrared light is blocked regardless of the angle of the incident light, the filter may include both thin-film dielectric layers and metal layers. The metal layers may be interleaved with the thin-film dielectric layers.

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.
