    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 internal 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.

    Abstract: A head-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.

    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 device may have a head-mounted housing. The housing may include a frame with left and right openings that receive respective left and right optical modules that present images to a user's eyes. Each optical module may have a lens and display that presents an image through the lens. Camera support members may be coupled to respective left and right peripheral portions of the frame. Each camera support member may have openings configured to receive cameras. Antennas may be formed on a camera support member. The antennas may have metal traces on a surface of the camera support member, may have conductive structures embedded within the camera support member, and/or may have patterned metal traces on printed circuits attached to or embedded in the camera support member. The cameras may operate through portions of a display cover layer that covers an outwardly-facing display on the head-mounted housing.

    Abstract: A head-mounted device may have optical modules that present images to the user's left and right eyes. The optical modules may move with respect to each other to accommodate different user interpupillary distances. Each optical module may have a lens barrel, a display coupled to the lens barrel that generates an image, and a lens mounted to the lens barrel through which the image is viewable from an eye box. The lens may be a multi-element lens formed from molded lens elements such as molded polymer lens elements. A lens element may be provided with protrusions that form lens tabs. The lens tabs may have coplanar lens tab surfaces that mate with corresponding coplanar mounting surfaces in the lens barrel. Alignment marks may be formed on the protrusions and/or other portions of the lens.
