Near-eye display systems, devices and methods
First Claim
1. A near-eye display device, comprising:
- a display unit having;
a liquid-crystal-on-silicon (LCOS) display for generating display light from illumination light incident thereon,a first polarizing beam splitter interface,an illumination module including at least one light source for generating the illumination light,a mirror for (i) receiving the illumination light from the illumination module after transmission of the illumination light through the first polarizing beam splitter interface and (ii) reflecting the illumination light back to the first polarizing beam splitter interface for reflection thereby toward the LCOS display, the mirror and the illumination module being positioned on opposite sides of the first polarizing beam splitter interface; and
a viewing unit for receiving the display light from the LCOS display after transmission of the display light through the first polarizing beam splitter interface, the viewing unit havingan imaging objective that forms an image of the LCOS display for a pupil based on the display light, anda second polarizing beam splitter interface for (i) reflecting reflected display light from the imaging objective towards the pupil and (ii) transmitting ambient light from an ambient scene towards the pupil, the second polarizing beam splitter interface and the first polarizing beam splitter interface being orthogonal to a common plane.

Abstract
A near-eye display device includes (a) a display unit having a liquid-crystal-on-silicon (LCOS) display and a first polarizing beam splitter interface for (i) reflecting illumination light from an illumination module towards the liquid-crystal-on-silicon display and (ii) transmitting display light from the LCOS display based on the illumination light, and (b) a viewing unit having an imaging objective that forms an image of the LCOS display for the pupil based on the display light, and a second polarizing beam splitter interface for (i) reflecting reflected display light from the imaging objective towards the pupil and (ii) transmitting ambient light from an ambient scene towards a pupil, the second polarizing beam splitter interface and the first polarizing beam splitter interface being orthogonal to a common plane.
