    摘要： An electronic device may have a display 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. 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.

    摘要： An electronic device may have a flexible organic light-emitting diode display layer. The edge of the flexible display layer may be bent. The display may have pixels formed from organic light-emitting diodes having anodes characterized by anode surface normals. For pixels in some regions of the display such as the bent edge of the display, the display may be characterized by a display surface normal for a pixel that differs from an anode surface normal for the anode of the organic light-emitting diode of that pixel. By tilting the anodes in this way, color shifts due to off-axis viewing of the pixels in the bend edge of the display can be minimized. If desired, tilted anodes may have multiple areas with different tilts. Sets of pixels with different anode tilts or other characteristics that differ may be supplied with common pixel data values.

    摘要： An electronic device may have a display with pixels configured to display an image. An image transport layer may be formed from a coherent fiber bundle or Anderson localization material. The image transport layer may overlap the pixels and may have an input surface that receives the image from the pixels and a corresponding output surface on which the received image is viewable. The image transport layer may form an exterior surface of the electronic device or may be overlapped by a transparent cover layer. Various methods such as swelling, piping, and slumping may be used to process fibers and form image transport layers. A fiber bundle that is used to form an image transport layer may include fibers that have varying properties.

    摘要： An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To increase the apparent resolution of the display in portions of the display panel with the transparent windows, the display may include a light spreading layer that includes a plurality of diffractive elements. The light spreading layer may spread visible light from the array of pixels such that the display resolution at the outer surface of the display is greater than at the display panel. The light spreading layer may selectively spread visible light but not infrared light. The display may also include a lens layer that focuses light onto the transparent windows.
