HYBRID OPTICS FOR NEAR-EYE DISPLAYS

摘要

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.

1. A method for displaying a near-eye light field display (NELD) image comprising:
determining a pre-filtered image to be displayed, wherein said pre-filtered image corresponds to a target image; displaying said pre-filtered image on a display; producing a near-eye light field after said pre-filtered image travels through a microlens array disposed adjacent to said display, wherein said near-eye light field is operable to simulate a light field corresponding to said target image; and altering said near-eye light field using at least one converging lens, wherein said altering allows a user to focus on said target image at an increased depth of field at an increased distance from an eye of said user and to increase spatial resolution of said target image.
