    Abstract: Asymmetrically strengthened glass articles, methods for producing the same, and use of the articles in portable electronic device is disclosed. The asymmetrically strengthened glass articles include glass articles having a deeper compressive stress layer in a thicker portion of the glass article. Using a budgeted amount of compressive stress and tensile stress, asymmetric chemical strengthening is optimized for the utility of a glass article. In some aspects, the strengthened glass article can be designed for reduced damage, or damage propagation, when dropped.

    Abstract: The disclosure provides members formed from multiple layers as well as enclosures and electronic devices that include the members. The members include glass members formed from multiple layers of glass. In some cases, the members include a protruding feature provided over a camera assembly of the electronic device. The member may define one or more through-holes that extend through the protruding feature. The protruding feature may define a textured region that may be configured to provide a matte or glossy appearance.

    Abstract: A display may have an array of display pixels that generate an image. A coherent fiber bundle may be mounted on the display pixels. The coherent fiber bundle may have a first surface that is adjacent to the display pixels and a second surface that is visible to a viewer. The coherent fiber bundle may contain fibers that carry light from the first surface to the second surface. The second surface may be planar or may have a central planar region and curved edge regions that run along opposing sides of the central planar region. The fibers may have cross-sectional surface areas with a first aspect ratio on the first surface and a second aspect ratio that is greater than the first aspect ratio on the second surface.

    Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of display pixels that provide image light to a user. The array of display pixels may form an active display structure with a rectangular shape. The rectangular active display structure may be surrounded by an inactive border region. Optical structures such as upper structures formed from a sheet of glass and lower optical structures that lie beneath the sheet of glass may be configured to bend light from the display pixels along the periphery of the active display structure. The upper optical structures may have an area that is larger than the area of the active display structure, so that the presence of the optical structures may serve to enlarge the apparent size of the display. The lower and upper optical structures may have curved surfaces for bending the light.
