Augmented/virtual reality near-eye displays with edge imaging lens comprising a plurality of display devices
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.
1. 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, wherein the common interface surface comprises an optical beam splitting element;
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; and
a reflective portion disposed on the top edge of the top portion of the spectacle lens or the bottom edge of the bottom portion of the spectacle lens, according to whichever of the top edge or bottom edge the image display device is not disposed on, the reflective portion having an optical power to focus light from the image display device, wherein the image display device and the reflective portion are rotated as a group around a vision line in opposite directions for a left eye and a right eye.
2. The near-eye display device of claim 1 , wherein a main area of the common interface surface is coated with partially reflective coating.
3. The near-eye display device of claim 2 , wherein the partially reflective coating has a transmittance of 80% and a reflectance of about 20%.
4. The near-eye display device of claim 1 , wherein the reflective portion being disposed on the bottom edge of the bottom portion has a different radius of curvature along two orthogonal directions and the viewer facing surface of the spectacle lens has a different radius of curvature along two orthogonal directions.
