Abstract: An optical system enables high image quality Head Mounted Displays to be made more compact and/or of reduced weight. The optical system includes at least two or more image panels per eye, two or more reflective surfaces per image panel, and a refractive eyepiece element. Light from each image panel is reflected by a distinct set of optical surfaces before reaching the eye, forming at least two overlapping virtual images per eye. The invention may allow the apparatus to have a compact form factor with weight distribution close to the user's face without compromising on image quality and resolution.

Abstract: A head-mounted display (1) includes: a liquid crystal display unit (2) including a display surface (7) facing forward, the liquid crystal display unit (2) configured to display an image on the display surface (7); an eyepiece lens (13) disposed at a position lower than the liquid crystal display unit (2); and a mirror unit (4) configured to reflect light based on the image displayed on the display surface (7) and guide the light thus reflected to the eyepiece lens (13).

Abstract: A head mounted display device includes a light source that emits a high coherence light beam, a beam expansion/diverging element that expands the light beam emitted by the light source, and a beam converging element that converges the expanded light beam into a viewing zone. The light beam from the beam converging element is incident onto a spatial light modulator (SLM), and the SLM is configured to add a phase pattern and/or an amplitude pattern to the light beam to generate a virtual image that is visible to a user wearing the head mounted display device. The light converging element creates a beam or scanning beam axis that converges towards the eye, which enables a large field of view for a virtual or holographic image to be displayed.

Abstract: A head-up-display (HUD) system includes at least one scanning laser projector operative to generate laser light, and a stacked array of multiple-switchable screens arranged relative to the projector to receive laser light generated by the projector, each screen of the stacked array of multiple-switchable screens spaced apart from one another and operative to switch between a transparent state and a diffusive state. A controller is operatively coupled to the stacked array of multiple-switchable screens, the controller configured to time sequentially switch each screen of the array from a transparent state to a diffusive state, wherein only one screen is switched to the diffusive state at any given time. An output of the projector is arranged at an angle or a distance from imaging optics succeeding the array of screens to prevent a specular beam emitted by the at least one scanning laser projector from intercepting the imaging optics succeeding the array of screens when all screens are in the transparent state.

Abstract: A wearable device includes a light source and a display unit. The display unit includes an image engine that controls the light source to generate image content for display, and a plurality of optical elements that direct the image content into a viewing zone. An eye monitor measures information pertaining to an eye configuration of a user wearing the wearable device, and the image content is visible to the user when the eye is aligned with respect to the viewing zone. A spatial light modulator (SLM) moves a position of the viewing zone based on the eye configuration information measured by the eye monitor. The eye monitor measures pupil size of the user, and the optical elements direct the image content into the viewing zone that is smaller in at least one dimension than twice the measured pupil size. The light source may include a micro-electro-mechanical systems (MEMS) scanning mirror.

Abstract: A head mounted display device includes a switchable light source that is switched to emit light for generating at least one viewing zone, and a panel illumination unit illuminated by the light source. The panel illumination unit converges the light onto an image panel that selectively transmits light at different pixels to generate image content. An eye monitor measures information pertaining to an eye configuration of a user, and the image content is visible to the user when the eye is aligned with respect to the viewing zone. The panel illumination unit converges the light such that light emitted by the image panel converges into the viewing zone positioned based on the eye configuration information measured by the eye monitor, with limited divergence such that when the display device is worn by the user, the image panel is located at a distance from the user's eye closer than a distance where the eye can focus the pixels.
