Abstract
A waveguide display includes a light source, a scanning mirror assembly, an output waveguide, and a controller. The light source emits image light. The scanning mirror assembly scans the image light as scanned image light to particular locations in accordance with scanning instructions. The output waveguide includes an input area and an output area. The output waveguide receives the scanned image light emitted from the scanning mirror assembly at the input area, and output expanded image light from a portion of the output area, the location of the portion of the output area based in part on a direction of the scanned image light output from the scanning mirror assembly. The controller generates the scanning instructions and provides the scanning instructions to the scanning mirror assembly.
