Abstract: An electronic device may have a display with pixels configured to display an image. The pixels may be overlapped by a cover layer. The display may have peripheral edges with curved cross-sectional profiles. An inactive area in the display may be formed along a peripheral edge of the display or may be surrounded by the pixels. Electrical components such as optical components may be located in the inactive area. An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels, may have an opening that overlaps portions of the inactive area, may have an output surface that overlap portions of the inactive area, and/or may convey light associated with optical components in the electronic device.

Abstract: An electronic device may have a display panel for displaying images. A display cover layer having curved portions may overlap the display panel. An image transport layer having an input surface that receives light from the display panel may convey the light from the input surface to an output surface adjacent to an inner surface of the display cover layer. The image transport layer may include fibers with different lengths to form a region of the output surface with a curved profile. Each fiber in the coherent fiber bundle may have a respective output face. The output face of each fiber in the curved edge region of the image transport layer may be parallel to the display panel or may be angled towards the center of the image transport layer. Image distortion control circuitry may modify image data to control the perceived distortion of the display.
