  • Patent number: 11079797
    Abstract: An electronic device may have a display with an array of pixels for displaying images. The display may have a window region. During operation, a component such as an optical component may operate through the window region. The window region may overlap a movable portion of the display. The window region may be operated in open and closed states. In the closed state, the movable portion of the display overlaps the window region and pixels in the movable display portion emit light through the window region. In the open state, the movable portion of the display is moved away from the window region so that light for the optical component may pass through the window region. The optical component may be a camera or other component that receives light through the window region or may be an optical component that emits light through the window region.

  • Patent number: 10983482
    Abstract: An electronic device such as a wristwatch device or other device may have a display. The display may be used to continuously display information such as watch face information. A watch face image on the display may contain watch face elements such as watch face hands, watch face indices, and complications. To reduce burn-in risk for watch face elements, control circuitry in the electronic device may impose burn-in constraints on attributes of the watch face elements such as peak luminance constraints, dwell time constraints, color constraints, constraints on the shape of each element, and constraints on element style. These constraints may help avoid situations in which static elements such as watch face indices create more burn-in than dynamic elements such as watch face hands.

  • Publication number: 20210064167
    Abstract: An electronic device such as a voice-controlled speaker device may have a cylindrical shape with upper and lower ends that have surface regions of compound curvature. The electronic device may have a display formed form an array of light-emitting devices such as light-emitting diodes. To provide the display with desired curvature (such as compound curvature), the display may be thermoformed. A flexible substrate for the display may be attached to a separate thermoplastic substrate. During a thermoforming process, the display may be heated such that the thermoplastic substrate softens into a pliable state. The display may then be molded into a desired shape. The display is then cooled to harden the thermoplastic substrate and secure the flexible substrate and light-emitting diodes in the desired shape. The thermoformed display may be stacked with additional functional layers such as a thermoformed touch-sensitive layer and/or a thermoformed lens layer.

  • Patent number: 10930710
    Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode or may be formed from other pixel structures such as liquid crystal display pixel structures. The pixels may emit light such as red, green, and blue light. An angle-of-view adjustment layer may overlap the array of pixels. During operation, light from the pixels passes through the angle-of-view adjustment layer to a user. The viewing angle for the user is enhanced as the angular spread of the emitted light from the pixels is enhanced by the angle-of-view adjustment layer. The angle-of-view adjustment layer may be formed from holographic structures recorded by applying laser beams to a photosensitive layer or may be formed from a metasurface that is created by patterning nanostructures on the display using printing, photolithography, or other patterning techniques.
