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 11):
A waveguide assembly comprising:\n an output waveguide to receive an image light emitted from a light source 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 a location of an eyebox in accordance with switching instructions; and a controller configured to generate the switching instructions and provide the switching instructions to the dynamic output grating.
