Abstract
An electronic device may have a display that displays an image and a display cover layer that overlaps the display. The display cover layer may have an image transport layer with an input surface that receives the image and a corresponding output surface to which the image is transported. The image transport layer may be formed from a coherent fiber bundle layer or a layer of Anderson localization material. The display cover layer may have a protective layer such as a protective glass layer that overlaps the image transport layer. A ring-shaped region of the display cover layer may have one or more structures with locally modified properties for arresting crack propagation across the display cover layer. The ring-shaped region may have one or more structures with locally reduced elasticity values or other structures that help arrest cracks.
