Abstract: A method of operating an AR system to display an image viewable by a user's eyes includes tracking, by an eye-tracking subsystem, a position of the user's eyes and determining, based on the position, a focus depth of the user's eyes. The method also includes selecting, from a plurality of light-guiding optical elements, a subset of light-guiding optical elements configured to focus light at a depth plane corresponding to the focus depth of the user's eyes, producing a plurality of light beams using a subset of sub-light sources of a plurality of sub-light sources, the subset of sub-light sources being configured to illuminate the subset of light-guiding optical elements, and imaging the plurality of light beams through an imaging system and onto the subset of light-guiding optical elements such that the image is generated at the depth plane corresponding to the focus depth of the user's eyes.

Abstract: Head-mounted virtual and augmented reality display systems include a light projector with one or more emissive micro-displays having a first resolution and a pixel pitch. The projector outputs light forming frames of virtual content having at least a portion associated with a second resolution greater than the first resolution. The projector outputs light forming a first subframe of the rendered frame at the first resolution, and parts of the projector are shifted using actuators, such that physical positions of light output for individual pixels occupy gaps between the old locations of light output for individual pixels. The projector then outputs light forming a second subframe of the rendered frame. The first and second subframes are outputted within the flicker fusion threshold. Advantageously, an emissive micro-display (e.g., micro-LED display) having a low resolution can form a frame having a higher resolution by using the same light emitters to function as multiple pixels of that frame.

Abstract: A wearable display system includes a light projection system having one or more emissive microdisplays, e.g., micro-LED displays. The light projection system projects time-multiplexed left-eye and right-eye images, which pass through an optical router having a polarizer and a switchable polarization rotator. The optical router is synchronized with the generation of images by the light projection system to impart a first polarization to left-eye images and a second different polarization to right-eye images. Light of the first polarization is incoupled into an eyepiece having one or more waveguides for outputting light to one of the left and right eyes, while light of the second polarization may be incoupled into another eyepiece having one or more waveguides for outputting light to the other of the left and right eyes. Each eyepiece may output incoupled light with variable amounts of wavefront divergence, to elicit different accommodation responses from the user's eyes.
