    Abstract: A head-mounted device may have optical modules that present images to a user's eyes. Each optical module may have a lens barrel with a display and a lens that presents an image from the display to a corresponding eye box. To accommodate users with different interpupillary distances, the optical modules may be slidably coupled to guide members such as guide rods. Actuators may slide the optical modules towards or away from each other along the guide rods. The guide rods may be formed from fiber-composite tubes with end caps that are fastened to a frame in the head-mounted device. The tubes may be partly or completely filled with cores to add strength. Low-friction coatings such as metal coatings may be formed on the fiber-composite tubes and the corresponding inner surfaces of the optical module structures that slidably engage the fiber-composite tubes.

    Abstract: A head-mounted display may include a display system and a lens system in a housing. The head-mounted display may include control circuitry that operates the head-mounted display in an active use mode and a protected mode. In the protected mode, the display system may be protected from collisions with the lens system. Placing the head-mounted display in the protected mode may include using an actuator to increase the distance between the display system and the lens system, may include injecting fluid between the display system and the lens system, and/or may include deploying a protective layer between the display system and the lens system. The control circuitry may determine whether to operate the head-mounted display in protected mode or active use mode based on sensor data, on/off status information, location information, and/or other information.

    Abstract: An electronic device such as a head mounted device may have a display that displays an image for a user. Head-mounted support structures may be used to support the display and to support lenses. The head-mounted support structures may have one or more lens barrels or other support members. Each lens may have an optical surface and a side surface. Adhesive may be used to attach the lenses to the head-mounted support structures. A first portion of the adhesive may bond each lens to a first respective portion of a support member and a second portion of the adhesive may bond each lens to a second respective portion of the support member. The adhesive may be a non-silicone adhesive that fractures in bulk rather than failing at interfaces with the lens and support member. The elastic modulus of the adhesive may help avoid cracking and plastic deformation during drop events.

    Abstract: In one aspect of the present disclosure, a display system is disclosed, such as a wearable head-mounted display (HMD), that includes an internal system housing and a movable display stack. The display stack includes a display panel, a carrier supporting the display panel, and a heat sink that are secured together such that the display panel, the carrier, and the heat sink are movable in unison within the system housing to adjust focus of the display panel. The carrier and/or the heat sink respectively include first and second thermal solutions to facilitate heat transfer away from the display panel, which may include a material having high thermal-conductivity properties and/or any structure that is configured to increase the exposed surface area of the carrier and/or the heat sink, such as projections or extensions (e.g., fins), recesses, slits, openings, or the like.

    Abstract: An optical module for a head-mounted device is configured to present content to a user. The optical module includes an optical module housing assembly, a display assembly, and an eye camera. The optical module housing assembly has a first end and a second end. The lens is connected to the optical module housing assembly and positioned at the first end of the optical module housing assembly. The display assembly is connected to the optical module housing assembly and is positioned at the second end of the optical module housing assembly. The display assembly is configured to cause the content to be displayed to the user through the lens. The eye camera is connected to the optical module housing assembly and is positioned at the second end of the optical module housing assembly. The eye camera is configured to obtain images through the lens.
