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.

Claims (44)

1. A near-eye display system, comprising:

a light source comprising a surface and a plurality of pixels having a pixel pitch of 5 microns or less, wherein the pixels are configured to emit light comprising an image;

a first aperture array located at an aperture distance from the surface of the light source, the aperture distance between 2 mm and 5 mm, the first aperture array comprising a first plurality of non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a first grid of equilateral triangles, a center of each of the first plurality of apertures being spaced from a center of each adjacent aperture by an aperture spacing of between 1 mm and 9 mm; and

a second aperture array between the first aperture array and the light source, the second aperture array comprising a second plurality of non-overlapping apertures,

wherein the first aperture array selectively passes the light emitted from the pixels to display the image without a double image condition, and wherein the plurality of pixels are greater in number than the first plurality of non-overlapping apertures.

2. The near-eye display system of claim 1 , wherein the light source and the first aperture array extend linearly in a lateral direction.

3. The near-eye display system of claim 1 , wherein the light source and the first aperture array are curved in two or three dimensions.

4. The near-eye display system of claim 1 , wherein each of the first plurality of non-overlapping apertures is a lens.

5. The near-eye display system of claim 4 , wherein each of the lenses has a spherical surface and a lens radius.

6. The near-eye display system of claim 1 , wherein each of the first plurality of non-overlapping apertures is an opening containing fluid.

7. The near-eye display system of claim 1 , wherein the aperture distance is a first aperture distance, and wherein the second aperture array is located at a second aperture distance less than the first aperture distance from the surface of the light source, the second plurality of non-overlapping apertures each centered on a vertex of an equilateral triangle within a second grid of equilateral triangles, and a center of each aperture of the second plurality of apertures being spaced from a center of each adjacent aperture of the second plurality of apertures by an aperture spacing of between 1 mm and 9 mm.

8. The near-eye display system of claim 1 , wherein each of the first plurality of non-overlapping apertures is bounded by a hexagon within the first grid.

9. The near-eye display system of claim 1 , further comprising:

a shutter display;

a processor; and

a multiplexing program comprising instructions executable by the processor to:

control the shutter display via temporal multiplexing to selectively provide the light emitted from the plurality of pixels to the non-overlapping apertures.

10. The near-eye display system of claim 1 , further comprising:

a processor;

an eye-tracking program comprising instructions executable by the processor to determine a location of an eye of a user; and

a rendering program comprising instructions executable by the processor to adapt a rendering of the pixels based on the location of the eye.

11. A method for displaying an image, comprising:

providing a light source comprising a surface and a plurality of pixels having a pixel pitch of 5 microns or less, wherein the pixels are configured to emit light comprising the image;

positioning an first aperture array at an aperture distance of between 2 mm and 5 mm from the surface of the light source, the first aperture array comprising a first plurality of non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a first grid of equilateral triangles, a center of each of the first plurality of apertures being spaced from a center of each adjacent aperture by an aperture spacing of between 1 mm and 9 mm, wherein the plurality of pixels are greater in number than the first plurality of non-overlapping apertures;

positioning a second aperture array between the first aperture array and the light source, the second aperture array comprising a second plurality of non-overlapping apertures; and

selectively passing the light emitted from the pixels to display the image without a double image condition.

12. The method of claim 11 , wherein the light source and the first aperture array extend linearly in a lateral direction.

13. The method of claim 11 , wherein each of the first plurality of non-overlapping apertures is a lens.

14. The method of claim 13 , wherein each of the lenses has a spherical surface.

15. The method of claim 11 , wherein each of the first plurality of non-overlapping apertures is an opening containing fluid.

16. The method of claim 11 , wherein the aperture distance is a first aperture distance, wherein the second aperture array is located at a second aperture distance less than the first aperture distance from the surface of the light source, the second plurality of non-overlapping apertures each centered on a vertex of an equilateral triangle within a second grid of equilateral triangles, and a center of each aperture of the second plurality of apertures being spaced from a center of each adjacent aperture of the second plurality of apertures by an aperture spacing of between 1 mm and 9 mm.

17. The method of claim 11 , wherein each of the plurality of non-overlapping apertures is bounded by a hexagon within the grid.

18. The method of claim 11 , further comprising:

determining a location of an eye of a user; and

adapting a rendering of the pixels based on the location of the eye.

19. The method of claim 11 , further comprising:

providing a shutter display; and

controlling the shutter display via temporal multiplexing to selectively provide the light emitted from the plurality of pixels to the non-overlapping apertures.

20. A near-eye display system, comprising:

a light source comprising a surface and a plurality of pixels having a pixel pitch of 5 microns or less, wherein the pixels are configured to emit light comprising an image;

a first aperture array located at a first aperture distance from the surface of the light source, the first aperture distance between 2 mm and 5 mm, the first aperture array comprising a first plurality of non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a first grid of equilateral triangles, a center of each of the apertures being spaced from a center of each adjacent aperture by an aperture spacing of between 1 mm and 9 mm; and

a second aperture array between the first aperture array and the light source, the second aperture array located at a second aperture distance less than the first aperture distance from the surface of the light source, the second aperture array comprising a second plurality of non-overlapping apertures that are each centered on a vertex of an equilateral triangle within a second grid of equilateral triangles, and a center of each aperture of the second plurality of apertures being spaced from a center of each adjacent aperture of the second plurality of apertures by an aperture spacing of between 1 mm and 9 mm, wherein the first aperture array and the second aperture array selectively pass the light emitted from the pixels to display the image without a double image condition.
