Abstract: An electronic device may have a housing with a display. The display may be 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. A wristwatch device may, as an example, have a rectangular or hexagonal input surface and may have an output surface such as a rectangular output surface with rounded corners or a circular output surface. A region of the output surface may have compound curvature. A portion of the image transport layer may protrude laterally over an inactive portion of the display.

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 are used to deform the image transport layer and the shape of the output surface. The area of peripheral portions of the output surface may expand relative to central portions. Optical uniformity across the output surface can be enhanced by maintaining uniformity in fiber core diameters and other attributes of the image transport layer across deformed and undeformed portions of the output surface.

Abstract: An electronic device may have a display mounted in a housing. The display may have a display panel with an array of pixels on a flexible substrate. A display cover layer may overlap the display panel. The flexible substrate may have a protruding portion that forms a tail. The tail may be coupled to a printed circuit on which a display driver integrated circuit and/or other circuitry is mounted. When the display is mounted in the housing, the tail may be bent back on itself to create a bend. The bend may be embedded in a molded polymer member. The molded polymer member may be attached to the housing with adhesive and may directly contact an inner surface of the display cover layer.
