Abstract
A display subsystem for a virtual image generation system. The display subsystem comprises a planar waveguide apparatus, and an optical fiber having a distal tip affixed relative to the planar waveguide apparatus, and an aperture proximal to the distal tip. The display subsystem further comprises at least one light source coupled the optical fiber and configured for emitting light from the aperture of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted to the drive assembly. The mechanical drive assembly is configured for displacing the aperture of the optical fiber in accordance with a scan pattern. The display subsystem further comprises an optical waveguide input apparatus configured for directing the light from the aperture of the optical fiber down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to the end user.
