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 farther 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.
