  • Publication number: 20200204764
    Abstract: A display device includes an array of light emitters and a mirror configured to reflect light from the light emitters toward an image plane. The display device further includes a controller configured to control the array of light emitters and the mirror to sweep the mirror through a range of angles, and selectively enable the light emitters during sweeping of the mirror. The selective enablement of light emitters, and the sweeping of the mirror, are configured to cause emitted light from the light emitters to project a plurality of pixels on/toward the image plane, with the pixels being spaced with a non-uniform resolution.

  • Publication number: 20200117006
    Abstract: A polarization-based dynamic focuser for a near-eye display includes a first polarizer configured to polarize environmental light incident on the first polarizer, such that environmental light passing through the first polarizer toward a user eye has a first polarity. An image source is positioned between the user eye and the first polarizer. The image source is transparent to the environmental light and is configured to output image display light toward the user eye, at least some of the image display light having a second polarity. A dynamic lens is positioned between the user eye and the image source, and is configured to selectively focus incident light having the second polarity toward the user eye at a controllable virtual distance, where the dynamic lens does not affect incident light having the first polarity.

  • Publication number: 20200110361
    Abstract: A holographic display system includes a holographic optical element (HOE), which includes a first volume hologram configured to outcouple light to form a first exit pupil upon satisfaction of a first angular condition, and a second volume hologram configured to outcouple light to form a second exit pupil upon satisfaction of a second angular condition. A light source is configured to introduce light into the HOE at any of a range of angles. A light source controller sets a current angle of the light to a first angle that meets the first angular condition, forming the first exit pupil. The light source controller moves the first exit pupil by changing the current angle to a second angle that meets the first angular condition. The light source controller redirects light to form the second exit pupil by setting the current angle to a third angle that meets the second angular condition.

  • Patent number: 10523930
    Abstract: Examples are disclosed herein related to reducing binocular rivalry in a near-eye display. One example provides a head-mounted display device having a near-eye display system configured to output a first-eye image to a first eyebox and a second-eye image to a second eyebox. The head-mounted display device is configured to receive an input of a three-dimensional (3D) location of a pupil of a first eye and a 3D location of a pupil of a second eye relative to the near-eye display system, based upon the 3D location of the pupil of the first eye and of the second eye, determine a location at which the pupil of the first eye begins to exit the first eyebox, and attenuate a luminance of the second-eye image at a location in the second-eye image based upon the location at which the pupil of the first eye begins to exit the first eyebox.

  • Patent number: 10108013
    Abstract: An augmented reality display system utilized in computing platforms such as wearable head-mounted display (HMD) devices includes a virtual reality display that is located in front of a user's eyes to provide a direct view of virtual world images. An optical periscope, comprising reflective or diffractive optical systems, is configured to provide an indirect view of the real world. By locating the virtual reality display (and its associated optical and electrical components) close to the user's eyes and within the user's direct line of sight, the field of view (FOV) of the virtual world is increased as compared with conventional indirect-view virtual reality displays. The optical periscope provides an FOV of the real world that would otherwise be obstructed by the positioning of the direct-view virtual reality display in front of the user's eyes.
