Abstract
A system and related methods for near-eye display of an image are provided. In one example, a near-eye display system includes a light source comprising a surface and a plurality of pixels having a pixel pitch of 5 microns or less. An aperture array is located between 2 mm and 5 mm from the surface of the light source. The aperture array comprises non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a grid of equilateral triangles. The center of each aperture is spaced from the center of each adjacent aperture by an aperture spacing of between 1 mm and 9 mm. The aperture array selectively passes the light emitted from the pixels to display the image without a double image condition.
