  • Patent number: 11817025
    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.

  • Patent number: 11810534
    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.
