  • Electronic devices having displays with curved surfaces
    Patent number: 11963425
    Abstract: An electronic device may have a display overlapped by a cover layer. Portions of the surface of the display and cover layer may have curved profiles. The display may include a flexible substrate and may have bent edge portions protruding from a central region. Gaps may be formed between regions of pixels on a common substrate or between separate display panels. Gap-overlapping structures may overlap the gaps to hide internal components from view or to blend the appearance of gaps with the appearance of adjoining portions of a display layer. The gap-overlapping structures may include light sources such as crystalline semiconductor light-emitting diodes. The diodes may emit light through light diffusing structures. Protruding display layer fingers and other structures may be used to accommodate display cover layer surfaces with curved profiles such as corner surfaces of compound curvature.

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.

  • Electronic devices with reduced stray light and ambient light reflections
    Patent number: 11860394
    Abstract: 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 help reduce ambient light reflections and stray light, light-absorbing structures may be incorporated into the image transport layer and other structures overlapping the display.

  • Electronic devices having housings with image transport layers
    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.

  • Distortion control in displays with optical coupling layers
    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.

  • Electronic devices with inhomogeneous image transport layers
    Patent number: 11747553
    Abstract: 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.

  • Electronic device with an optical coupling layer and diffractive layer
    Patent number: 11650368
    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.

  • Local Passive Matrix Displays
    Publication number: 20230087088
    Abstract: A display may be formed by an array of light-emitting diodes mounted to the surface of a display substrate. The light-emitting diodes may be inorganic light-emitting diodes formed from separate crystalline semiconductor structures. An array of pixel control circuits may be used to control light emission from the light-emitting diodes. Each pixel control circuit may be configured to control one or more respective passive matrices. To control partial pixel cells in the display, a donor pixel control circuit in a partial pixel cell may control the pixels in a receptor partial pixel cell without a pixel control circuit. To mitigate the size of an inactive area of the display, fanout signal lines for the display may be formed in the light-emitting active area of the display. The fanout signal lines may be formed between a row of pixel control circuits and a bottom edge of the light-emitting active area.
