Abstract: An electronic device may have a hinge that allows the device to be flexed about a bend axis. A display may span the bend axis. To protect display elements such as pixel circuitry from excessive mechanical stress, the display may include one or more structural protective layers. A structural layer may be incorporated into the display stack as a supportive backing behind the pixel circuitry and/or as a protective cover over the pixel circuitry. The structural layer may include rigid portions and flexible portions. The flexible portions may contain flexible material that separates and adjoins adjacent rigid structures or that fills grooves between adjacent rigid portions. The rigid portions may be formed from thin sheets of glass or other transparent materials. The flexible material in the structural layer may be an elastomeric material having a refractive index that matches that of the glass sheets in the structural layer.

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 pixels. The pixels may form one or more displays. The displays may be flexible organic light-emitting diode displays or other displays. The electronic device may have first and second display layers that face away from each other and display images in different directions. Image transport layers may overlap the display layers and may have curved edges that overlap a sidewall portion of the electronic device. Image transport layers receive images at input surfaces and transport the received images to corresponding output surfaces. Image transport layers may be provided with hemispherical shapes and other shapes having output surfaces of compound curvature. A folding device may have first and second displays that are overlapped by respective first and second image transport layers that join over a hinge to block the hinge from view. A wristwatch device may have links or other structures with an image transport layer.

Abstract: An electronic device may have a display layer for displaying images. An optical coupling layer having an input surface that receives light from the display panel may convey the light from the input surface to an output surface. The output surface may have different dimensions than the display layer and may have any desired shape. To account for the displacement of light between the active area and the outer surface of the optical coupling layer and to ensure the output image is perceived with the desired distortion, image data may be rendered for the output surface then modified to account for the distortion and displacement that will occur later when the image is transported by the optical coupling layer from the display active area to the output surface of the optical coupling layer. Image distortion control circuitry may modify the rendered image data based on a distortion map.

Abstract: An electronic device may have a display that displays an image. The image may be viewed through a display cover layer that overlaps the display. The display cover layer may include an optical coupling layer such as a coherent fiber bundle. A pixel expansion layer such as a diffractive layer may be incorporated between the optical coupling layer and a protective layer. The diffractive layer may create duplicate pixels to occupy otherwise non-light-emitting areas on the output surface of the display cover layer. The diffractive layer may also create duplicate pixels that overlap adjacent pixels to allow for brightness averaging. An adhesive layer or the protective layer may be used to form diffractive elements for the diffractive layer. An adhesive layer having a high index of refraction may be interposed between the optical coupling layer and the display panel to mitigate undesired reflections of ambient light.
