1. A head-mounted display device comprising:
- an integrated processor for handling virtual content for display;
an integrated image source for introducing the virtual content, the integrated image source including;
a reflective pixel array of individually addressable pixels, the reflective pixel array configured to form a virtual display image based on the virtual content,a light source configured to illuminate the pixel array, anda polarization-sensitive surface configured to receive illumination from the light source, to reflect the illumination onto the pixel array, and to transmit the image formed by the pixel array, the polarization-sensitive surface opposing the pixel array and curving away from the pixel array by more than half a width of the pixel array; and
a beam-splitting assembly configured to receive the virtual display image transmitted through the polarization-sensitive surface and to redirect the virtual display image to a viewing location, in combination with external imagery.

Abstract
An interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content, wherein the height of the image source is at least 80% of a display active area width of the optical assembly.

15. A head-mounted display device comprising:
-
an integrated processor for handling virtual content for display; a reflective pixel array of individually addressable pixels, the reflective image array configured to form a virtual display image based on the virtual content; a light source configured to illuminate the pixel array; a polarization-sensitive surface configured to receive illumination from the light source, to reflect the illumination onto the pixel array, and to transmit the image formed by the pixel array, the polarization-sensitive surface opposing the pixel array and curving away from the pixel array by more than half a width of the pixel array; and a beam splitter positioned obliquely in front of a viewing location, the beam splitter configured to receive the virtual display image transmitted through the polarization-sensitive surface and to redirect the virtual display image away from the viewing location; and a partially reflective focusing mirror arranged between the beam splitter and external imagery, the focusing mirror configured to receive the virtual display image reflected off the beam splitter and to reflect a portion of the virtual display image, with changed polarization state, back through the beam splitter and into the viewing location, in combination with external imagery transmitted through the focusing mirror and the beam splitter. - View Dependent Claims (16, 17, 18, 19)

20. A head-mounted display device comprising:
-
an integrated processor for handling virtual content for display; a reflective pixel array of individually addressable pixels, the reflective pixel array configured to form a virtual display image based on the virtual content; a light source configured to illuminate the pixel array; a polarization-sensitive surface configured to receive illumination from the light source, to reflect the illumination onto the pixel array, and to transmit the image formed by the pixel array, the polarization-sensitive surface opposing the pixel array and curving away from the pixel array by more than half a width of the pixel array; and a beam-splitting assembly configured to receive the virtual display image transmitted through the polarization-sensitive surface and to redirect the virtual display image to a viewing location, in combination with external imagery transmitted directly into the viewing location along an optical axis, the virtual display image received at less than 80 degrees from the optical axis.
