Abstract:
The disclosed apparatus may include (1) a plurality of monochromatic emitter arrays, where each of the plurality of monochromatic emitter arrays has a plurality of emitters disposed in a two-dimensional configuration and emits a monochromatic image of a corresponding color, (2) a waveguide configuration that includes (a) a top surface, (b) a bottom surface disposed opposite the top surface, (c) a coupling area that receives the monochromatic images, and (d) a decoupling area that projects a plurality of instances of a polychromatic image including a combination of the monochromatic images toward an eyebox through the bottom surface, and (3) an actuator system that produces lateral shifting of the plurality of instances of the polychromatic image between at least two positions relative to the waveguide configuration. Various other methods and systems are also disclosed.
