Abstract: Systems and methods are disclosed for low motion-to-photon latency for augmented and virtual reality systems. Some systems generate rendered frames that are presented to a user by outputting light from a head-mounted display unit. The rendered frames are perceived by the user as virtual content. The head-mounted display unit includes an orientation sensor, a display configured to output light to the user, and processors. The processors receive a rendered frame of virtual content, obtain orientation information from the orientation sensor, and warp or modify the rendered frame of virtual content based on changes to the orientation of the user's head. The warped rendered frame is subsequently outputted from the display using modulated light. The processors and the orientation sensor may be part of a spatial light modulator for modulating the light used to present the warped rendered frame. In addition, the spatial light modulator may be a LED array having low persistence and a high duty cycle.

Abstract: A wearable display system includes one or more emissive micro-displays, e.g., micro-LED displays. The micro-displays may be monochrome micro-displays or full-color micro-displays. The micro-displays may include arrays of light emitters. Light collimators may be utilized to narrow the angular emission profile of light emitted by the light emitters. Where a plurality of emissive micro-displays is utilized, the micro-displays may be positioned at different sides of an optical combiner, e.g., an X-cube prism which receives light rays from different micro-displays and outputs the light rays from the same face of the cube. The optical combiner directs the light to projection optics, which outputs the light to an eyepiece that relays the light to a user's eye. The eyepiece may output the light to the user's eye with different amounts of wavefront divergence, to place virtual content on different depth planes.

Abstract: Embodiments transform an image frame based on a position of pupils of a viewer to eliminate visual artefacts formed on an image frame displayed on a scanning-type display device. An MR system obtains a first image frame corresponding to a first view perspective associated with a first pupil position. The system receives data from an eye tracking device, determines a second pupil position, and generates a second image frame corresponding to a second view perspective associated with the second pupil position. A first set of pixels of the second image frame are shifted by a first shift value, and a second set of pixels of the second image frame are shifted by a second shift value, where the shift values are calculated based on at least the second pupil position. The system transmits the second image frame to a near-eye display device to be displayed thereon.

Abstract: Embodiments shifts the color fields of a rendered image frame based on the eye tracking data (e.g. position of the user's pupils). An MR device obtains a first image frame having a set of color fields. The first image frame corresponds to a first position of the pupils of the viewer. The MR device then determines a second position of the pupils of the viewer based on, for example, data receive from an eye tracking device coupled to the MR device. The MR device generates, based on the first image frame, a second image frame corresponding to the second position of the pupils. The second image frame is generated by shifting color fields by a shift value based on the second position of the pupils of the viewer. The MR device transmits the second image frame to a display device of the MR device to be displayed thereon.
