Abstract: Disclosed methods of aligning display projector assemblies included in head-mounted displays may include (1) determining an optical angle of an output of a display projector assembly relative to a base of the display projector assembly, (2) physically altering, based on the determined optical angle of the output of the display projector assembly, a mating structure included within a frame such that, when the base of the display projector assembly is mated to the frame via the mating structure, the output of the display projector assembly is optically aligned with the frame along a predetermined optical axis, and (3) mating the base of the display projector assembly to the frame via the altered mating structure. Various other methods, systems, and apparatuses are also disclosed.

Abstract: Optical assemblies may include a projector assembly, a waveguide, and at least two standoffs. The projector assembly may include at least one light projector and a housing. The waveguide may include at least one input grating corresponding to the at least one light projector. The standoffs may be between the housing and the waveguide, and may be configured for aligning the at least one light projector with the at least one input grating. Related head-mounted displays, systems, and methods are also disclosed.

Abstract: Methods of assembling a head-mounted display (HMD) may include coupling a first digital projector assembly to an HMD frame, coupling a second digital projector assembly to the HMD frame, and then warping the HMD frame to optically align the first digital projector assembly with the second digital projector assembly. The warped HMD frame may be fixed such that the first digital projector assembly and the second digital projector assembly are optically aligned to within a predetermined threshold. Various other methods and systems are also disclosed.

Abstract: Optical assemblies may include a projector assembly and a waveguide assembly. The projector assembly may include at least one light subprojector and a housing including at least one receptacle. The waveguide assembly may include a waveguide and a waveguide holder. The housing may include at least one receptacle and the waveguide holder may include at least one support leg. The support leg may be positioned within, and secured to, the receptacle to align the projector assembly with the waveguide assembly. Related head-mounted displays, systems, and methods are also disclosed.
