Autostereoscopic display
First Claim
1. An autostereoscopic display supplying a viewer with a stereoscopic image when viewed from an intended perspective, comprising:
- a pixel array including individual pixels each having subpixel elements, N individual pixels being arranged into an individual pixel groups, wherein N is equal to the number of individual perspective images to be displayed, each said pixel including plural subpixels extending in a horizontal direction from the viewer'"'"'s intended perspective and forming a part of an individual perspective image;
a first lenticular array positioned vertically from the viewer'"'"'s intended perspective and focusing light from said subpixels of each said pixel to a single spatial point between said pixel array and the viewer;
each said pixel group in the horizontal direction being focused by a different first lens of said first lenticular array; and
a second lenticular array positioned between said first lenticular array and the viewer such that images projected from different pixels of each pixel group are directed to a different location at an intended viewing point, the spacing of the images from each pixel of said pixel groups being separated at the intended viewing position at about the spacing between human eyes to thereby display said plural images stereoscopically, wherein said first lenticular array focuses said subpixels to the surface of a lens of said second lenticular array.

Abstract
An autostereoscopic display and method of displaying multidimensional images involves a first lenticular array preferably of cylindrical lenses positioned between a viewer and a pixel array, and a second lenticular array also preferably of cylindrical lenses positioned between the first lenticular array and the viewer. The pixel array includes several pixel groups that project images through corresponding groups of first lenses within the first lenticular array. A pitch of the lenses within the second lenticular array differs from a pitch of the lenses in the first lens groups within the first lenticular array. The display can be manufactured or retrofit with the first and second lenticular arrays. By use of the first lenticular array, light from plural color pixels may be focussed to a single point so that color subpixels arranged in a direction transverse to the direction of the cylindrical lenses of the first lenticular array may be focussed to a single point on the secondary lenticular array and then as a single image to the user.

8. An autostereoscopic display, comprising:
-
a pixel array including several pixel groups;
a first lenticular array positioned between the pixel array and a viewer, said first lenticular array comprising a plurality of first lenses corresponding respectively to the pixels of the pixel array such that such that the lenses of said first lenticular array include a plurality of first lens groups corresponding to said pixel groups; and
a second lenticular array positioned between the first lenticular array and a viewer such that images projected from first lenses within each first lens group pass through a corresponding one of several lenses within the second lenticular array, wherein a pitch of lenses within the second lenticular array differs from a pitch of the first lens groups within the first lenticular array where a stereoscopic image is produced by at least one of said first and second lenticular arrays. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method of displaying multidimensional images on an autostereoscopic display, comprising:
-
generating images using a pixel array including several pixel groups;
projecting the images generated by each pixel through a corresponding plurality of first lenses of a first lenticular array, thereby projecting the images through several first lens groups; and
projecting the images projected through each first lens group through a different and corresponding one of several second lenses within a second lenticular array that is positioned between the first lenticular array and a viewer, the further projecting involving projecting the images through second lenses having a pitch that differs from a pitch of the first lens groups within the first lenticular array. - View Dependent Claims (19, 20, 21, 22, 23)
