Abstract
A display and method of displaying multidimensional images on an autostereoscopic display includes establishing a lenslet array to include a plurality of lens elements. There is an interlacing of a plurality of multiple images on the display with a fanning of the multiple images out into an angular array. The method establishes a plurality of views in a vertical and horizontal direction. A mapping of a plurality of views onto a plurality of pixels makes up the display and a three dimensional image is generated from the fanned out multiple images.

An autostereoscopic display for supplying a stereoscopic image when viewed from an intended viewing perspective, comprising:
- a pixel array including a plurality of pixels, each of the plurality of pixels having at least two subpixel elements extending in a horizontal direction from the intended viewing perspective;
- and a lenslet array including a plurality of lenses, the lenslet array positioned between the intended viewing perspective and the pixel array, the lenslet array configured to transpose a focus orientation associated with the at least two subpixels of the each pixel from a generally vertical orientation to a generally horizontal orientation such that the at least two subpixel elements are within the transposed focus orientation and the transposed focus orientation is generally diagonal;
- wherein at least the each pixel is focused by a corresponding one of the plurality of lenses.
An autostereoscopic display, comprising:
- a pixel array including a plurality of pixel groups;
- a lenslet array positioned between the pixel array and a viewing perspective, the lenslet array including a plurality of lenses corresponding generally to a plurality of pixels of the pixel array such that each of the plurality of lenses of the lenslet array corresponds to each of the pixel groups;
- and
- wherein the lenslet array is configured to transpose a focal orientation of at least two of the plurality of lenses.
An autostereoscopic display, comprising:
- a pixel array including a plurality of pixel groups;
- a lenslet array positioned between the pixel array and a viewing perspective, the lenslet array including a plurality of lenses corresponding generally to a plurality of pixels of the pixel array such that each of the plurality of lenses of the lenslet array corresponds to each of the pixel groups;
- and
- where the lenslet array is configured to transpose a focal orientation of at least two of the plurality of lenses, and
- wherein each of the plurality of color pixels includes a plurality of color components arranged in a first direction, and the plurality of lenses of the lenslet array include a plurality of rotated cylindrical lenses having a transposed axis extending from around a second direction to around the first direction generally perpendicular to the second direction.
An autostereoscopic display, comprising:
- a pixel array including a plurality of pixel groups;
- a lenslet array positioned between the pixel array and a viewing perspective, the lenslet array including a plurality of lenses corresponding generally to a plurality of pixels of the pixel array such that each of the plurality of lenses of the lenslet array corresponds to each of the pixel groups;
- and
- where the lenslet array is configured to transpose a focal orientation of at least two of the plurality of lenses, and
- wherein each of the pixels includes at least two color components arranged in a horizontal direction with respect to the display, and the plurality of lenses of the first array include rotated cylindrical lenses having a transposed axis extending from around a vertical direction to around the horizontal direction with respect to the display according to a diagonal axis of rotation.
A method of displaying multidimensional images on an autostereoscopic display, comprising:
- generating one or more images using a pixel array, the pixel array including a plurality of pixels;
- projecting portions of the one or more images generated by each of the plurality of pixels through a corresponding plurality of lenses of a lenslet array;
- and transposing the projected portions of the one or more images from a substantially vertical focus orientation to a substantially horizontal focus orientation by rotating the focal axis of the plurality of lenses.
An array of cylindrical lenses each formed using grayscale Deep Reactive Ion Etching to have a diagonal focal axis wherein the diagonal focal axis extends from a generally vertical orientation toward a generally horizontal orientation.
An autostereoscopic display for supplying a stereoscopic image when viewed from an intended viewing perspective comprising:
- a lenslet array including a plurality of lens elements;
- a cylindrical axis running down the center of each said lens element in said lenslet array and wherein said cylindrical axis can be tilted at an angle that is dependent upon a layout and an orientation of a plurality of display pixels of said autostereoscopic display where said tilting rotates the image of said pixels so that any position a gap between said pixels is spread between a set of views.
A method of displaying multidimensional images on an autostereoscopic display comprising:
- establishing a lenslet array to include a plurality of lens elements;
- interlacing a plurality of multiple images on said display, the multiple images composed of pixels, the pixels having horizontally aligned color pixels having vertical focal orientation;
- fanning said multiple images out into an angular array;
- establishing a plurality of views in a vertical and horizontal direction by rotating at least one of the vertical focal orientations;
- and
- mapping said plurality of views onto a plurality of pixels making up said display;
- and generating a three dimensional image from said fanned out multiple images.
