Abstract: A Head Mounted Display (HMD) includes a pixel array having multiple pixels configured in a two-dimensional surface, each pixel providing multiple light beams forming an image provided to a user. The HMD also includes a first optical element configured to provide a central portion of a field of view for the image through an eyebox that limits a volume including a pupil of the user, and a second optical element configured to provide a peripheral portion of the field of view for the image through the eyebox, wherein the peripheral portion of the field of view comprises at least one steradian of a user's field of view at a resolution of at least fifteen arcminutes.

Abstract: A beam scanner includes a substrate, a tiltable reflector hingedly supported by the substrate, and a reflective polarizer. The reflective polarizer is supported over the tiltable reflector and configured to receive and redirect a light beam towards the tiltable reflector for scanning the light beam. A projector includes the beam scanner and a light source providing a light beam. The light beam may be modulated in brightness, color, or polarization synchronously with tilting the reflector, thereby forming an image in angular domain after propagating through a pupil-replicating waveguide. At least one folding mirror may be provided for directing the light beam from the light source around the pupil-replicating waveguide, resulting in a compact overall configuration.

Abstract: A wearable device for augmented reality applications including an image generation engine to generate multiple light rays forming an image, and an eyepiece including a display to project the image to a user for an augmented reality application, is provided. The eyepiece includes a planar waveguide configured to transmit the light rays from the image generation engine. The wearable device also includes at least one optical element configured to couple the light rays into, and to provide the light rays from, the planar waveguide and through an eyebox limiting a volume that includes a pupil of the user, and a user-functional portion of the eyepiece including the at least one optical element, the user-functional portion shaped according to a pre-selected format that is aesthetically appealing to an onlooker when the immersive reality device is worn by a user.

Abstract: A display device includes a display, an optical assembly, and a display-moving assembly connected to the display for moving the display between a first position and a second position. When in the first position, the display outputs image light in a first direction substantially parallel to an optical axis of the optical assembly. When in the second position, the display is positioned away from the optical axis of the optical assembly. The display device also includes a partial reflector and a partial reflector-moving assembly connected to the partial reflector for moving the partial reflector between a third position and a fourth position. When the partial reflector is in the third position, the display is in the first position and the display is disposed between the optical assembly and the partial reflector. When the partial reflector is in the fourth position, the display is in the second position.
