Abstract: A glass sheet having asymmetric chemical strengthening is disclosed and described. The examples described herein are directed to a cover glass for an electronic device and other glass components that may be used as enclosure elements or may form an enclosure. Within the glass component, localized compressive stress regions may be formed on opposite sides of the glass component, which may help arrest or redirect propagating cracks or defects in the glass. The opposing compressive stress regions may also help maintain the overall flatness of the component while increasing strength and/or impact resistance of the component.

Abstract: Glass articles and methods for producing glass articles for a portable electronic device are disclosed. Properties of the glass articles, such as cover members, are improved through chemical strengthening, thermoforming, or a combination thereof. The glass articles may include barrier layers to prevent diffusion of ions between glass layers of the glass article, internal compressive stress regions, or a combination thereof.

Abstract: Electronic devices including a display layer and a cover layer including a foldable region are disclosed herein. The display layer and the cover layer are configured to be moved between a folded configuration and an unfolded configuration by bending the cover layer along the foldable region. Methods of making a cover layer for an electronic device are also disclosed.

Abstract: An electronic device may have a display that displays an image and a display cover layer that overlaps the display. The display cover layer may have an image transport layer with an input surface that receives the image and a corresponding output surface to which the image is transported. The image transport layer may be formed from a coherent fiber bundle layer or a layer of Anderson localization material. The display cover layer may have a protective layer such as a protective glass layer that overlaps the image transport layer. A ring-shaped region of the display cover layer may have one or more structures with locally modified properties for arresting crack propagation across the display cover layer. The ring-shaped region may have one or more structures with locally reduced elasticity values or other structures that help arrest cracks.
