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 an image transport layer formed from optical fibers. Extruded filaments of binder material may be fused together to form a layer of binder for the image transport layer. Each filament may contain multiple embedded optical fibers. As a result of the extrusion process, the optical fibers may be characterized by increasing lateral deformation at increasing distances from the center of the filament in which the optical fibers are embedded. Tension variations and variations in the orientation angle of the fibers in the image transport layer can be maintained below desired limits to ensure satisfactory optical performance for the image transport layer. The optical fibers and binder may be formed from polymers or other clear materials.
