Examples are disclosed that relate to mixed reality display devices. One example provides a head-mounted display device comprising, a display, a lens system, and a curved Fresnel combiner. The curved Fresnel combiner is configured to direct light received from the display via the lens system toward an eyebox, and is at least partially transmissive to background light.

A wearable display device according to an embodiment may comprise: a first prism, positioned in front of a user's eye, for controlling the path of an incident light and enabling the arrival of a virtual image to be displayed on the eye; a second prism, coupled to the first prism, for reducing distortion of a real image arriving at the user's eye; and a coating layer which is interposed between the first prism and the second prism and of which the brightness is controlled in inverse proportion to the ambient brightness, such that the visibility of the virtual image increases.

A head mounted display for a user that uses a display screen to produce images. The head mounted display includes a frame. The frame has a pair of lenses. The pair of lenses has their optical centers biased away from their physical centers. The head mounted display includes a strap which attaches to the frame and fits about the user's head to hold the frame to the user's head. A method for viewing images by a user.

The present invention is directed to an optical device for augmented reality using total internal reflection, the optical device including: an optical means for transmitting at least part of real object image light toward the pupil of an eye of a user; wherein a total internal reflection space configured to transfer augmented reality image light, output from an image output unit, toward the pupil of the eye of the user is formed inside the optical means; and wherein the total internal reflection space is filled with a medium having an index of refraction lower than the index of refraction of the optical means, and the augmented reality image light transferred to the total internal reflection space through the inside of the optical means is reflected by total internal reflection on the total internal reflection space and then transferred toward the pupil of the eye of the user.

Illumination devices as include a frame intended to be worn by a user and one or more light sources (e.g., LEDs) positioned by the frame so as to be near a user's zygomatic bones and oriented to project light in a direction of the user's view when the illumination device is worn on the wearer's head. The frame may be shaped to be worn over the user's ears and behind the user's head, and may be made of one or more of plastic, metal and/or a metal alloy, carbon fiber, wood, cellulose acetate, natural horn and/or bone, leather, and an epoxy resin. An optional strap may be retractably attached to connect portions of the frame over the wearer's head. The LEDs may be included in respective panels swivelly mounted to booms of the frame and the panels may further include imaging devices, such as a camera, and/or a projector.

An apparatus having an asymmetric adjustable lens with a deformable optical element. The apparatus may also include one or more actuators coupled to a deformable element of the asymmetric adjustable lens in a direct-drive configuration such that (1) mechanical action of the one or more actuators applies force to the deformable optical element and (2) the force applied by the mechanical action of the one or more actuators changes an optical property of the asymmetric adjustable lens by deforming the deformable optical element. Various other devices, systems, and methods are also disclosed.

An extended reality headset is configured to position and stabilize the headset on a face when worn. For example, the headset can include an external frame with first and second side pieces coupled to a display structure and configured to provide lateral stabilization. In some examples, the headset can include a front head-engaging structure front head-engaging structure that is rotationally coupled to the external frame via a pivot point. The headset can also include a rear head-engaging structure coupled the external frame. In some examples, the rear head-engaging structure can include a tensioning mechanism to adjust the headset to fit various head shapes. Additionally, the headset can include a flexible strap coupled to the front head-engaging structure and the tensioning mechanism. In some examples, applying tension to the flexible strap by the tensioning mechanism can cause the front head-engaging structure to rotate along the pivot point, providing a secure fit.

A mirror device includes a frame body, a shaft member provided inside the frame body and connected to the frame body at both end portions, and a reflection member fixed to the shaft member and provided so as to be capable of swinging around an axis of the shaft member. The reflection member has a base portion provided along an axial direction of the shaft member and a reflection portion provided on the base portion. The base portion has a three-dimensional uneven structure including a bottom wall portion having a main surface provided along the axial direction of the shaft member and a plurality of side wall portions extending from the bottom wall portion on the side opposite to the reflection portion.

A head mounted display, according to various embodiments of the present disclosure, comprises: a housing comprising an opening part; an lens assembly arranged in the opening part; and a light shielding part arranged along the circumference of the opening part, wherein the light shielding part may be in a first configuration of being drawn out from the housing via the opening part so as to enable being worn on the face of a user, and a second configuration of having at least one portion thereof inserted into the housing via the opening part.

A one-piece display has a main display area at least partly viewable from one point of observation, and a secondary display area arranged so as to not be viewable from that point of observation. The main display area and the secondary display area are arranged relative to one another in such a way that the secondary display area is reflected in the main display area to produce a virtual display plane that is viewable from the point of observation.
