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.
Claims18
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, where the lenslets have varying shape and size, redirecting light from the subpixels creating several views.

- said autostereoscopic array having at least a first and second lenslet, wherein a first vector corresponding to the first axis of the first lenslet and a second vector corresponding to the first axis of the second lenslet intersect at a non-zero second angle.
A method of autostereoscopic displaying a 3-D image comprising:
- placing a lenticular array before a pixel array, the pixel array transmitting light, where the pixel array has at least one pixel, where the pixel has subpixels, and where the subpixels have gaps between the subpixels;
- generating N individual perspective views using N groups of pixels in the pixel array;
- and
- passing the light from the pixel array through the lenticular array, where the individual perspective views combine to form a 3-D autostereoscopic image, the lenticular array composed of lenslets, each lenslet being of independent shape and size, each lenslet having 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, the lenslet having a radius of curvature, where the lenticular array blurs an image of the gaps by choosing the first angle, where the lenslets have varying shape and size, redirecting light from the subpixels creating several views.
