    Abstract: An electronic device may have a display with pixels configured to display an image. An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels and may have an input surface that receives the image from the pixels and a corresponding output surface on which the received image is viewable. The image transport layer may form an exterior surface of the electronic device or may be overlapped by a transparent cover layer. Various methods such as swelling, piping, and slumping may be used to process fibers and form image transport layers. A fiber bundle that is used to form an image transport layer may include fibers that have varying properties.

    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 such as a fiber optic plate. The fiber optic plate may be formed from a bundle of fibers. The fibers may be formed using fiber extruding equipment. Each fiber may have a core covered with a cladding, a stray light absorbing layer, and binder material. The fibers may be deformed in a heated chamber by pressing inwardly with a die that has a recess, causing the fibers to bulge into the recess. A cutter can be used to cut off a layer of the deformed fibers. This layer may be machined and polished to form the fiber optic plate.

    Abstract: An electronic device may have a display overlapped by an image transport layer such as a coherent fiber bundle or layer of Anderson localization material. The image transport layer may have an input surface that receives an image from the display and a corresponding output surface to which the image is transported. The input surface and output surface may have different shapes. During fabrication of the image transport layer, molding techniques, grinding and polishing techniques, and other processes may be used to deform the image transport layer and the shape of the output surface. To accommodate differences in material deformation and other factors that vary as a function of position across the image transport layer, the image transport layer may be formed from canes of fibers or other material with one or more properties that vary as a function of position.
