Abstract
A system for near-eye display applications. A lens is provided with a beam-splitting interface horizontally along the width of the lens. Two display devices per lens are provided and disposed on the perimeter surface of the lens opposing an overlapped, prismatic facet optics assembly which balances aberration introduced by the slight symmetry break in the lens.
Claims36
A near-eye display device comprising:
- a lens prism assembly comprising a viewer-facing surface, a scene-facing surface, a vertical dimension, a horizontal dimension and a lens thickness, wherein the lens prism assembly comprises an upper portion and a lower portion bonded together along a horizontal interface;
- a beam-splitting element defined on the horizontal interface;
- two or more display devices disposed on a first edge of the lens prism assembly, each display device configured to couple an optical image through the lens thickness;
- and
- a reflective element disposed on a second edge of the lens prism assembly, wherein the reflective element or the beam-splitting element comprises a plurality of overlapping, prismatic facet elements that are configured to transmit separate optical images in a predetermined interlaced pattern, and
- wherein the beam-splitting element is configured to couple the transmitted optical images through the viewer-facing surface to an eye pupil of a user.
A near-eye display device having an elongated eye box with a horizontal dimension that is larger than its vertical dimension, the near-eye display device comprising:
- a supporting frame that mounts the near-eye display device on a user's face;
- a spectacle lens mounted on the supporting frame through which the real world is viewed, the spectacle lens including a view-facing surface and a scene-facing surface, wherein the spectacle lens is composed of a top portion and a bottom portion bonded together at a common interface surface;
- an image display device disposed on an edge of the top portion of the spectacle lens or on an edge of the bottom portion the spectacle lens, the image display device projecting light from the display device into the eye of the user.
A near-eye display device having an elongated eye box with a horizontal dimension that is larger than its vertical dimension, the near-eye display device comprising:
- a supporting frame that mounts the near-eye display device on a user's face;
- a spectacle lens mounted on the supporting frame through which the real world is viewed, the spectacle lens including a view-facing surface and a scene-facing surface;
- and
- two or more image display devices disposed at an upper edge of the spectacle lens or at a lower edge of the spectacle lens, each image display device projecting light from the image display device into an eye of a user.
