A head mounted display includes first and second light source modules, a light reversely turning module, an image output module, first and second eyepiece modules, and a beam splitting mirror. The first and second light source modules are respectively configured to emit first and second lights. The image output module is configured to receive the first and second lights, generating first and second image lights with corresponding image information respectively. The light reversely turning module is optically coupled between the first light source module (or the second light source module) and the image output module, making a propagating direction of the first light (or the second light) in reverse to that of the first image light (or the second light). The beam splitting mirror is optically coupled between the image output module and the first/second eyepiece module, guiding the first/second image light into the first/second eyepiece module.

The disclosure relates generally to a display panel, which in at least some situations includes multiple separate stacked layers or components that are combined together, such as to have one emission layer component with numerous pixels that emit light, and to have at least one control logic layer component that includes integrated circuits or other logic to control the emission of light by the pixels in the emission layer. The different layers may be separate silicon chips or wafers that are connected in a stacked structure via a flip chip technique, with the emission layer using AMOLED or other OLED pixels. The display panels may be designed and/or configured for use in head mounted displays (e.g., with a fully immersive virtual reality system). The disclosure also relates generally to techniques for manufacturing, testing and/or otherwise using such a display panel in various manners.

A display apparatus (1) for use in displaying an image to a viewer, comprising a transparent optical waveguide display unit (2) arranged for receiving image-bearing light (4) into the optical waveguide display unit, for guiding the received light therealong to an output area (24) thereof, and for outputting from the output area the image-bearing light (6) collimated to present a viewable image. A light-emitting display screen (3) arranged adjacent to and behind the output area of the optical waveguide display unit is visible therethrough behind the output area (24). This combines the light from the light-emitting display screen (e.g. imagery) with the viewable image (6).

A head-up display system comprises a microprojector, first and second viewer optics, a redirection optic, and an electronic controller. Switchable electronically between first and second optical states, the redirection optic is configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic. The electronic controller is configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on first image data. The electronic controller is further configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.

Embodiments described herein include an augmented reality (AR) optical system, and associated method and computer program product, defining a field of view relative to an optical reference point. The optical system comprises an imagery display configured to display images using a received first display signal, and a beam-splitter disposed within the field of view and configured to cause the displayed images to appear in a first focal plane within the field of view. The optical system further comprises an occluding display disposed within the field of view and configured to display, based on the first display signal, occluding images in a second focal plane nearer to the beam-splitter than the first focal plane, thereby reducing environmental light at the optical reference point for at least a portion of the displayed images.

A surgical navigation system includes: a tracker (125) for real-time tracking of a position and orientation of a robot arm (191); a source of a patient anatomical data (163) and a robot arm virtual image (166); a surgical navigation image generator (131) generating a surgical navigation image (142A) including the patient anatomy (163) and the robot arm virtual image (166) in accordance to the current position and/or orientation data provided by the tracker (125); a 3D display system (140) showing the surgical navigation image (142A).

A head mounted display device includes a display panel and a lens assembly mounted so that an optical axis of the lens assembly intersects the display panel. The lens assembly includes a lens body having a surface facing the display panel and defining Fresnel prisms. A Fresnel prism of the Fresnel prisms has a first facet angle when viewed in a first cross-section and has a second facet angle when viewed in a second cross-section parallel to the first cross-section. The first facet angle is different than the second facet angle.

A portable virtual reality device, which is provided with a board having a length to correspond the focal distances of the left and right lens; left and right supporting boards that are deployed and folded left and rightward on a front surface of the board based on the board; left and right lens plates that are deployed and folded left and rightward on a rear surface of the board based on the board. The smart phone is mounted simply to correspond to the focal distances of the left and right lens when it is used, and when it is carried, the left and right lens plates and the left and right supporting boards are fold to form a thin film to be carried conveniently.

In a general aspect, a virtual reality headset can include a goggle portion having a chassis including left, right, top and bottom sides. The chassis can be open at a first end and a second end. The first end can be configured for placement against or near a user's face. The second end can be configured to receive an electronic device including a display. The goggle portion can also include a lens frame assembly disposed within the chassis and disposed between the first end and the second end. The headset can also include an enclosure flap hingably coupled with the goggle portion at a first end of the enclosure. A second end of the enclosure flap can be removably attachable to the chassis to secure the electronic device in the VR headset. The goggle portion and the enclosure flap can be a unitary structure formed from a single precision-cut sheet.

A head mounted display is provided that includes a main body, a sensor, and a door. The door of the head mounted display includes a computing device or, in some cases, an embedded screen. The computing device includes a camera and a display interface. The sensor and the camera of the mobile computing device are rigidly positioned with fixed displacements.
