Describe herein are electronic devices that include a display stack having a cover component atop a display component. In some instances, the cover component includes an anti-reflective stack having multiple layers tuned to reduce the amount of natural light reflected at a user of the device. In some cases, an anti-fingerprint coating may be applied over the anti-reflective stack to provide an exterior surface to the display stack.

Cover assembly for electronic devices

A touch-sensitive display for an electronic device may include a touch sensor comprising a low birefringence substrate, ultraviolet (UV) stabilizers, and a metal mesh disposed on at least a portion of the low birefringence substrate. The low birefringence characteristic of the touch sensor substrate causes the touch sensor to exhibit low haze, high transmittance, and substantially no color, which provides improved optical properties over conventional touch sensor substrate materials used with metal mesh film. In some embodiments, the retardation value of the touch sensor substrate may be no greater than about 15 nanometers (nm). Additionally, the UV stabilizers prevent the substrate from yellowing and becoming brittle from exposure to UV radiation.
