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.

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.

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 help reduce ambient light reflections and stray light, light-absorbing structures may be incorporated into the image transport layer and other structures overlapping the display.

Abstract: An electronic device includes a substrate, a set of light emitters on the substrate and arranged in a plurality of axisymmetric light emitter groups, a set of lenses including a different lens disposed over each axisymmetric light emitter group of the plurality of axisymmetric light emitter groups, and a set of optical fibers. At least one optical fiber in the set of optical fibers has a proximal end, a distal end, and a bend between the proximal end and the distal end. The proximal end is positioned to receive light, through a respective lens in the set of lenses, from the light emitters of a respective axisymmetric light emitter group in the plurality of axisymmetric light emitter groups.
