Abstract
An electronic device may have a housing with a display. A protective display cover layer for the display may have an image transport layer formed from fibers or Anderson localization material. The image transport layer may include light absorbing material. Light absorbing material may be incorporated as an additive into a component of the image transport layer such as the binder layer of a coherent fiber bundle or the cladding of fibers in the image transport layer. The image transport layer may also be formed from fibers with a light absorbing layer formed in addition to a transparent cladding. The image transport layer may be formed from Anderson localization material that has light absorbing material. Fibers for the image transport layer may be extruded with light absorbing portions. A polymer preform having light absorbing material may be drawn to form fibers for the image transport layer.
