Hybrid optics for near-eye displays
First Claim
1. A system for displaying a NELD image comprising:
- a display comprising a plurality of pixels;
a computer system coupled with said display and operable to cause said display to render a target image;
a microlens array disposed adjacent to said display and comprising a plurality of microlenses, wherein said microlens array is operable to produce a near-eye light field array corresponding to said target image that simulates a field corresponding to said target image, wherein said display and said microlens array are disposed within a near-eye range of an observer; and
at least one converging lens disposed between said microlens array and an expected position of an eye of said observer, wherein the microlens array is displaced from the converging lens, and wherein said at least one converging lens alters said near-eye light field array to allow said observer to focus on said target image at an increased depth of field at an increased distance from an eye of said observer.

Abstract
A method for displaying a near-eye light field display (NELD) image is disclosed. The method comprises determining a pre-filtered image to be displayed, wherein the pre-filtered image corresponds to a target image. It further comprises displaying the pre-filtered image on a display. Subsequently, it comprises producing a near-eye light field after the pre-filtered image travels through a microlens array adjacent to the display, wherein the near-eye light field is operable to simulate a light field corresponding to the target image. Finally, it comprises altering the near-eye light field using at least one converging lens, wherein the altering allows a user to focus on the target image at an increased depth of field at an increased distance from an eye of the user and wherein the altering increases spatial resolution of said target image.

11. An apparatus for displaying a NELD image comprising:
-
a curved display comprising a plurality of pixels, operable to display a pre-filtered image corresponding to a target image; and a curved microlens array disposed adjacent to said display and comprising a plurality of microlenses, wherein said microlens array produces a near-eye light field array corresponding to said target image that simulates a field corresponding to said target image, wherein said display and said microlens array are disposed within a near-eye range of an observer; and at least one converging lens, wherein said at least one converging lens further alters said near-eye light field array emitted from said microlens array to allow said observer to focus on said target image at an increased depth of field at an increased distance from an eye of said observer, wherein said at least one converging lens is the displaced from said curved microlens array. - View Dependent Claims (12, 13, 14, 15, 16)
