Abstract: An electronic device may include a display having a waveguide that propagates image light and having optics such as a tint layer or bias lens mounted to the waveguide by a ring of adhesive. The ring may laterally surround an air cavity between the optics and the waveguide. A surface relief grating may be mounted to the waveguide within the air cavity. One or more air flow channels may be provided in the ring of adhesive and/or the optics to constrain air flow out of the air cavity on the time scale of a drop or impact event. This may configure the air cavity to maintain its volume during the event, effectively forming an air cushion for components in the air cavity. The air flow channels may pass air between the air cavity and the environment on the time scale of environmental ambient pressure changes.
