摘要： The disclosed head-mounted display assemblies may include a first eyecup and a second eyecup that are configured for positioning in front of intended locations of a user's eyes. The first eyecup and the second eyecup may be movable relative to each other to adjust for an interpupillary distance of the user's eyes. The head-mounted display assemblies may also include a single near-eye display screen configured for displaying an image to the user through the first eyecup and the second eyecup. A flexible shroud may be positioned to provide a seal between a first interior volume of the first eyecup, a second interior volume of the second eyecup, and the single near-eye display screen. Various other methods, devices, systems, and assemblies are also disclosed.

摘要： Systems and methods for implementing head mounted displays may include lens movement assemblies. A head mounted display system includes a display housing surrounding one or more display devices, a first lens and a second lens. An input device on the display housing includes a control member moveable between a first position and a second position. A lens movement assembly is operatively coupled to the input device and the first and second lenses and is configured to move the first lens relative to the second lens in response to movement of the control member between the first position and the second position.

摘要： Embodiments relate to a metal frame in a head-mounted display (HMD) that is structured to absorb impact and protect components of the HMD. The metal frame has a wall that is spaced away from a protection shell securing a display panel in the HMD. When the HMD is dropped or subject to external force, the wall may deform but keep the protection shell intact. Moreover, the metal frame has protruding ridges and brackets that surround outward facing cameras on the HMD. If the HMD is dropped, the protruding ridges and brackets can provide protection to the cameras.

摘要： A backplate for a head-mounted display (HMD) is disclosed. The backplate provides structural support as well as thermal cooling for components coupled to the backplate. The backplate includes a plurality of mounting regions that are used to couple components to the backplate. The mounting regions may include camera mounting regions (e.g., for inside-out tracking), an inertial measurement unit (IMU) mounting region, circuit board mounting regions, heat pipe mounting region, and a fan mounting region. The mounting regions may be specific to the component. In various embodiments, the backplate is a single diecast metal plate that includes the mounting regions designed to provide certain levels of thermal management, stiffness, and conductivity (e.g., ground) for the HMD.

摘要： An inter-pupillary distance (IPD) adjustment mechanism for a head-mounted display (HMD) is disclosed. The IPD adjustment mechanism is coupled to a structural plate of the HMD and to an eyecup for each eye that includes a lens and display assemblies. The IPD adjustment mechanism includes an arm for each optical assembly, and a gear that interfaces with the arms. In one embodiment, each arm is a rack gear that interfaces with a pinion gear. The eyecups are each mounted on one or more rails that allow for the eyecups to adjust a distance between the eyecups along a single dimension. Accordingly, movement of the gear causes both eyecups to move either away from or towards each other. In some embodiments, the IPD adjustment mechanisms is driven by a motor. In some embodiments, the IPD adjustment mechanism is manually controlled by the user.

摘要： A lens assembly can be removably attached to an eye cone of a HMD. The eye cone displays images to an eye of a user of the HMD. The eye cone includes a peripheral wall that extends towards rear of the HMD. The lens assembly includes a corrective lens and a frame. The corrective lens corrects a vision error of the eye of the user. The frame includes an inner surface onto which the corrective lens is attached. The frame also includes a wall that receives a peripheral wall of the eye cone for removably securing the lens assembly to the HMD. The HMD can include another eye cone that displays images to the other eye of the user. Another lens assembly can be removably attached to the other eye cone.

摘要： A display assembly of a head mounted display (HMD) includes a pancake lens display assembly. The pancake display assembly comprises a first lens with a quarter-waveplate and a partially reflective surface, a second lens with a reflective polarizer, and a display. An alignment system positions the first lens relative to the second lens to align the reflective polarizer of the second lens with the quarter-waveplate of the first lens. The alignment system rotates the first lens about an optical axis to position the quarter-waveplate on the first lens such that the quarter-waveplate and the reflective polarizer on the second lens are at an angle where light transmitted through the second lens and then through the first lens is substantially circularly polarized. The alignment system mounts the second lens to the lens housing such that the quarter-waveplate is at the angle relative to the reflective polarizer.
