PACKAGING STRUCTURE OF HEAD MOUNTED TERMINAL AND HEAD MOUNTED TERMINAL
A packaging structure of head mounted terminal and a head mounted terminal are disclosed. The packaging structure comprises an annular rear casing and a soft rubber member, and the soft rubber member is disposed between the rear casing and two lenses of the head mounted terminal. The outer edge of the soft rubber member is fixed on the inner ring of the rear casing, the soft rubber member comprises two lens barrels arranged symmetrically, and the two lens barrels are respectively sleeved on the two lenses of the head mounted terminal. The soft rubber member further comprises an extending and folding part disposed on an outer periphery of the lens barrel, which is used to realize the extension of the lens barrel with the left and right movement of the lens.
Virtual image display apparatus and video device unit manufacturing method
An image display device is a self-luminous type device including a light emitting portion, and a casing portion of a display device unit has a heat dissipating structure portion through which a part of the image display device is exposed for heat dissipation. In manufacturing the display device unit, when performing simple and reliable assembly while securing a high heat dissipation characteristic, for example, by using characteristics of a silicon substrate, high accurate positioning is performed in a display device positioning portion.

The VR integrated machine includes a heat generating device, a heat conducting member and thermoelectric conversion member, the heat conducting member is connected with the heat generating device, the thermoelectric conversion member has a first end connected with the heat conducting member, and is configured to generate electrical energy and to supply the electrical energy to the UR integrated machine.
See-through computer display systems with adjustable zoom cameras
Aspects of the present invention relate to methods and systems for the see-through computer display systems with adjustable-zoom cameras positioned such that their respective capture fields-of-view at least partially overlap at a target distance.
Display systems and methods for determining registration between display and eyes of user
A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the HMD. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and provides feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.
HEAD-MOUNTED DISPLAY APPARATUS
A head-mounted display apparatus includes a support member that supports a first display unit and a second display unit that display images, an extension member extending in a second direction intersecting a first direction along a direction from the first display unit to the second display unit, and a coupling member coupling the support member to the extension member, in which the support member has a first coupled portion coupled to the extension member, the extension member has a second coupled portion coupled to the support member, and a thickness (width) of the first coupled portion is thicker (wider) than a thickness (width) of the second coupled portion in a third direction intersecting the first direction and the second direction.
Partial electronic see-through head-mounted display
A partial electronic see-through HMD includes one or more subassemblies that occlude a central portion of a user's field of view (the peripheral portions of the user's field of view may remain unobstructed). Each subassembly includes an outward facing camera, a display, and an eyepiece. Images of the occluded central zone are captured by the camera and projected to the user via the display and eyepiece. The projected images can also include electronic information, such as AR image overlays. The peripheral zones are not occluded and remain directly viewable by the user. Thus, the projected images complete (or partially complete) the user's FOV of the external environment between the peripheral zones and may provide additional electronic information to the user.
Reflective eyepiece optical system and head-mounted near-to-eye display device
The present invention relates to a reflective eyepiece optical system and a head-mounted near-to-eye display device. The system includes: a first optical element and a second optical element arranged successively along an incident direction of an optical axis of human eyes, and a first lens group located on an optical axis of an miniature image displayer. The first optical element is used for transmitting and reflecting an image light from the miniature image displayer. The second optical element includes one optical reflection surface. The first optical element reflects the image light refracted by the first lens group to the second optical element, and then transmits the image light reflected by the second optical element to the human eyes. The effective focal lengths of the first sub-lens group and the second sub-lens group are a combination of positive and negative.
Virtual and augmented reality systems and methods
A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.
Display device including foveal and peripheral projectors
An augmented reality headset may include a reflective holographic combiner to direct light from a light engine into a user's eye while also transmitting light from the environment. The combiner and engine may be arranged to project light fields with different fields of view and resolution to match the visual acuity of the eye. The combiner may be recorded with a series of point to point holograms; one projection point interacts with multiple holograms to project light onto multiple eye box points. The engine may include a laser diode array, a distribution waveguide, scanning mirrors, and layered waveguides that perform pupil expansion and that emit wide beams of light through foveal projection points and narrower beams of light through peripheral projection points. The light engine may include focusing elements to focus the beams such that, once reflected by the holographic combiner, the light is substantially collimated.
