Autostereoscopic 3-d display

Abstract

A lenslet array having variously shaped and sized lenslets, where the lenslets are rotated and/or tilted, reducing gap images in an image formed by pixels/subpixels, where the pixel/subpixels have gaps between each other forming the gap images.

1 . An autostereoscopic array, comprising: a lenticular array, the lenticular array having at least one lenslet, each lenslet being of independent shape and size, where each lenslet has at least a first and a second axis, where the first axis is parallel to a line corresponding to a center of curvature of a face of the lenslet, and the second axis bisects a projection of the lenslet, where vectors corresponding to each axis intersect at a non-zero first angle and the lenslets have at least one radius of curvature measured from the center of curvature, where the lenticular array, if positioned before a pixel array having subpixel elements with gaps between the subpixels, will blur an image of the gaps by choosing a rotation angle corresponding to a projection of the first angle.  
   
   
       2 . The autostereoscopic array of  claim 1 , where at least one lenslet is spherically symmetric.  
   
   
       3 . The autostereoscopic array of  claim 1 , where at least one lenslet is cylindrical symmetric.  
   
   
       4 . The autostereoscopic array of  claim 3 , where the at least one lenslet is cylindrically convex.  
   
   
       5 . The autostereoscopic array of  claim 3 , where the at least one lenslet is cylindrically concave.  
   
   
       6 . The autostereoscopic array of  claim 1 , where a tilt angle is chosen instead of the rotation angle to blur an image of the gaps of non-illumination, where the tilt angle is a rotation of a lenslet into or out of the plane of the lenticular array, where the reference surface is defined by at least one of the intersection of the centers of the lenslets and the intersection of tangents of the first axis of lenslets.  
   
   
       7 . The autostereoscopic array of  claim 6 , where the reference surface is curved in shape or where the reference surface is a flat plane.  
   
   
       8 . The autostereoscopic array of  claim 1  having at least a first and second lenslet, wherein a first vector corresponding to the second axis of the first lenslet and a second vector corresponding to the second axis of the second lenslet intersect at a non-zero angle.  
   
   
       9 . The autostereoscopic array of  claim 1 , wherein the first angle is variable.  
   
   
       10 . A method of fabricating a lenticular array for use in a 3-D autostereoscopic display comprising: 
 interfacing a master mold with an optical substance, where the interfacing includes at least one of pressing the mold against the optical substance and pouring the optical substance into the mold;    curing the optical substance, where curing includes at least one of cooling the optical substance, chemically treating the optical substance, and radiative treating the optical substance; and    removing the master mold from the cured optical substance forming a lenticular array made of the optical substance, the lenticular array being composed of lenslets, each lenslet being of independent shape and size, where each lenslet has at least a first and a second axis, where the first axis is parallel to a line corresponding to a center of curvature of a face of the lenslet, and the second axis bisects a projection of the lenslet, where vectors corresponding to each axis intersect at a non-zero first angle and the lenslets have at least one radius of curvature measured from the center of curvature, where the lenticular array, if positioned before a pixel array having subpixel elements with gaps between the subpixels, will blur an image of the gaps by choosing a rotation angle corresponding to a projection of the first angle.
