Abstract
In one preferred form illustrated in FIG. 1 there is provided an autostereoscopic display 10. The display 10 includes a layer 20 of pixel sources 22. The display includes a source screen 12 and a lens structure 14. The source screen 12 is able to separate light from each pixel source 22, in the layer 20 of pixel sources 22, into view position input sources 32 each corresponding with a different view position 40. The lens structure 14 has a view position configuration 36 and a views configuration 38. The view position configuration 36 and the views configuration 38 of the lens structure 14 are able to transmit light, that is received from the view position input sources 32 as corresponding lens structure inputs 34, as views 39 grouped in viewing positions 40.

1-24. (canceled)
A lens arrangement for a layer of pixels in an autostereoscopic display, the lens arrangement causing a single image to be projected to a plurality of viewing positions, the lens arrangement comprising:
- a first screen disposed in front of the layer of pixels, the first screen having a plurality of groups of openings therethrough, each of the pixels aligned with one of the groups of openings;
- a first plurality of lenticular lenses disposed in front of the first screen, each of the lenticular lenses in the first plurality of lenticular lenses receiving a plurality of light beams from each of the plurality of pixels that pass through the openings in the first screen;
- and
- a second plurality of lenticular lenses disposed in front of the first plurality of lenticular lenses, the second plurality being smaller in number than the first plurality of lenticular lenses, the first and second plurality of lenticular lenses causing the same image to be projected to a plurality of viewing positions, each of the plurality of viewing positions having the same image simultaneously.
A method of providing autostereoscopic images, the method comprising:
- providing a first screen disposed in front of a layer of pixels emanating light therefrom, each of the pixels aligned with a group of openings in the first screen to provide a number of light beams from each pixel;
- providing a first plurality of lenticular lenses disposed in front of the first screen, each of the first plurality of lenticular lenses receiving the light beams from a single group of openings in the first screen;
- providing a second plurality of lenticular lenses disposed in front of the first plurality of lenticular lenses, the second plurality of lenticular lenses being smaller than the first plurality of lenticular lenses, the first and second plurality of lenticular lenses causing an image to be projected to a plurality of viewing positions, each of the plurality of viewing positions having the same image simultaneously.
