    Abstract: In devices with flexible displays, multilayer adhesive stacks may be included. A multilayer adhesive may attach a flexible display panel to the display cover layer in an electronic device. Including multiple layers of adhesive in the adhesive stack (as opposed to a single layer) provides more degrees of freedom for the timing and optimization of the properties of the adhesive stack. The multilayer adhesive stack therefore has better performance than if only a single layer of adhesive is used. The multilayer adhesive stack may include one or more layers of soft adhesive, hard adhesive, hard elastomer, hard polymer, and/or glass to optimize the mechanical and optical performance of the multilayer adhesive stack. Soft adhesive layers may be included to optimize lateral decoupling (e.g., during folding and unfolding) of the adhesive stack. Harder layers may be included to provide rigidity and prevent denting during impact events.

    Abstract: A foldable electronic device may bend about a bend axis. A foldable display panel may be configured to bend along the bend axis as the foldable device is folded. A display cover layer may overlap the display panel. The display panel may have an array of pixels configured to display an image viewable through the display cover layer. The display cover layer may be formed from a layer of glass. A recess may be formed in the layer of glass that runs parallel to the bend axis and that overlaps the bend axis. The recess forms a flexible locally thinned portion in the glass that allows the display cover layer to bend. A rough surface texture and polymer coating may be provided in the recess. The recess may have shallowly sloping walls.

    Abstract: A foldable electronic device may have a foldable housing. The foldable housing may be configured to bend about a bend axis. First and second portions of the housing that rotate relative to each other may be coupled by a hinge that is aligned with the bend axis. A foldable display may be coupled to the foldable housing and may be configured to bend along the bend axis as the foldable housing is folded. The display may have an array of pixels supported by a metal layer. The pixels may be interposed between a display cover layer and the metal layer. The foldable housing may have a support layer. To help support the display for bending about the bend axis while preventing damage to the display when the display is contacted by an external object, a spring layer may be interposed between the metal layer and the support layer.
