Abstract: A head-mounted display device employs controllable aperture projection for uniformity of a waveguide display within a field of view and eyebox domain. A waveguide-based display to control pupil replication density may comprise an image panel to provide light, a projection lens to receive and focus the light from the image panel, a variable aperture to pass the focused light in a controllable manner, and a waveguide to project the focused light passed through by the variable aperture onto an eye box, wherein the variable aperture is positioned at an entrance of the waveguide.
