    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.

    Abstract: One aspect provides an apparatus for locking circuit boards in position between a pair of guide rails. The apparatus can include a slider attached to a sidewall of one guide rail. The slider is allowed to slide along the guide rail within a predetermined range and one or more plunger-and-spring assemblies. A respective plunger-and-spring assembly comprises a plunger and a spring surrounding the plunger, and the plunger is inserted into a through-hole on the sidewall of the guide rail such that a first end of the plunger can be aligned with a notch on a corresponding circuit board and a second end of the plunger is in contact with the slider. Sliding of the slider causes the spring to compress and decompress and the first end of the plunger to move in and out of the notch on the circuit board, thereby facilitating locking and unlocking of the circuit board.
