A display subsystem (104) for a virtual image generation system (100), comprising at least one waveguide (202); an optical fiber (256); at least one light source (250); a drive assembly (258) configured to manipulate the optical fiber (256) such that a distal end (256b) of the optical fiber (256) is displaced about a fulcrum (260) according to a scan pattern; an optical modulation apparatus (276) configured to converge the light emitted from the distal end (256b) of the optical fiber (256); an optical waveguide input apparatus (272) configured to direct the light by the optical modulation apparatus (276) into the at least one waveguide (202) such that the virtual image generation system (100) displays the one or more image frames..
