Abstract:
A near-eye-display (NED) includes an eye tracking system and a waveguide display. The eye tracking system tracks locations based on a location of the user's eyes. The waveguide display includes a light source, an output waveguide and a controller. The output waveguide includes a dynamic output grating that outputs an expanded image light to the tracked eyebox locations. The decoupling grating is a 2D array of spatially switchable liquid crystal (LC) pixels including an active subset of LC pixels emitting light only to regions within the tracked eyebox locations. The decoupling grating dynamically out-couples the expanded image light to the tracked location based on switching instructions generated and provided by the controller.

Claim (Index 1):
A near-eye-display (NED) system comprising:\n an eye tracking system configured to track a location of an eye of a user of the NED; a light source configured to emit an image light; an output waveguide to receive the image light and to expand the image light in at least one dimension; a dynamic output grating comprising an active set of liquid crystal (LC) gratings that are configured to direct the expanded image light from the output waveguide to the location of the eye of the user in accordance with switching instructions; and a controller configured to generate the switching instructions and provide the switching instructions to the dynamic output grating.
