1. A light guide display with antireflection film, comprising:
a plurality of aligned magnifying layers providing a viewing surface, each magnifying layer including:
a plurality of aligned light guides, each light guide having an input end, a midsection and a magnifying output end;
the plurality of output ends aligned in substantially contiguous parallel contact as a single layer;
the plurality of input ends aligned as an input surface; and
an antireflection film disposed upon the input surface, the input surface is optically coupled to, and physically separate from, an image source.
2. The light guide display of claim 1 , wherein the antireflection film comprises a coating.
3. The light guide display of claim 1 , wherein the antireflection film comprises a layer.
4. The light guide display of claim 1 , wherein the antireflection film comprises an adhesive laminate.
5. The light guide display of claim 1 , wherein the antireflection film comprises a plurality of thin-film layers.
6. The light guide display of claim 1 , wherein the antireflection film is intimately joined to the input surface.
7. The light guide display of claim 1 , wherein the antireflection film comprises an integral part of the input surface.
8. The light guide display of claim 1 , wherein the antireflection film enhances optically coupling the input surface to the image source.
9. The light guide display of claim 1 , wherein the midsection is flexible.
10. The light guide display of claim 1 , wherein the area of the aligned input ends is substantially less than the area of the aligned magnifying output ends.
11. The light guide display of claim 1 , wherein each light guide has a longitudinal center, the input end being about perpendicular to the longitudinal center, the magnifying output end being angled relative to the longitudinal center.
12. A light guide display with antireflection film, comprising:
a plurality of aligned magnifying layers providing a viewing surface, each magnifying layer including:
a plurality of light guides, each light guide having an input end, a midsection and a magnifying output end;
the plurality of input ends aligned;
the plurality of output ends aligned in substantially contiguous parallel contact as a single layer;
the plurality of aligned input ends aligned as an input surface;
a louver layer coupled to the aligned magnifying ends; and
an antireflection film disposed upon the input surface, the input surface is optically coupled to, and physically separate from, an image source.
13. The light guide display of claim 12 , wherein the antireflection film comprises a coating.
14. The light guide display of claim 12 , wherein the antireflection film comprises a layer.
15. The light guide display of claim 12 , wherein the antireflection film comprises an adhesive laminate.
16. The light guide display of claim 12 , wherein the area of the aligned input ends is substantially less than the area of the aligned magnifying output ends.
17. The light guide display of claim 12 , wherein each light guide has a longitudinal center, the input end being about perpendicular to the longitudinal center, the magnifying output end being angled relative to the longitudinal center.
18. A light guide display with antireflection film, comprising:
a case
a plurality of aligned magnifying layers disposed within the case and providing a viewing surface, each magnifying layer including:
a plurality of aligned light guides, each light guide having an input end, a midsection and a magnifying output end;
the plurality of magnifying output ends aligned in substantially contiguous parallel contact as a single layer;
the plurality of input ends aligned as an input surface;
an antireflection film disposed upon the input surface; and
at least one image source disposed within the case proximate to and physically separate from the input surface, the antireflection film enhancing the optical coupling of the input surface to the image source.
19. The light guide display of claim 18 , wherein the antireflection film comprises a coating.
20. The light guide display of claim 18 , wherein the antireflection film comprises a layer.
21. The light guide display of claim 18 , wherein the antireflection film comprises a plurality of thin-film layers.
22. The light guide display of claim 18 , wherein the antireflection film comprises an integral part of the input surface.
23. The light guide display of claim 18 , wherein the area of the aligned input ends is substantially less than the area of the aligned magnifying output ends.
24. The light guide display of claim 18 , wherein each light guide has a longitudinal center, the input end being about perpendicular to the longitudinal center, the magnifying output end being angled relative to the longitudinal center.
25. The light guide display of claim 18 , further including a louver layer coupled to the aligned magnifying output ends.
