Display device with eyepiece assembly and display on opto-mechanical support
First Claim
1. A compact display device for transmitting an image to a user'"'"'s eye, the display device comprising:
- an opto-mechanical support fixture comprising an elongated member configured to allow passage of ambient light across a direction of elongation of the elongated member to a user'"'"'s eye, the support fixture defining an illumination path along the elongated member;
a display supported by the support fixture and operative to provide an image, the display located to receive illumination light on the illumination path; and
an eyepiece assembly supported by the support fixture in proximity to the display to receive the image from the display and to direct the image to the user'"'"'s eye, wherein the eyepiece comprises a polarization beam-splitter coating, a quarterwave plate, and a focusing mirror arranged so that polarized light from the display passes the beam-splitter coating and the quarterwave plate and is reflected from the focusing mirror to pass in the opposite direction through the quarterwave plate and is reflected from the beam-splitter coating toward the eye.

Abstract
A compact, head-mountable display device for transmitting an image to a user'"'"'s eye is provided. The display device includes a support fixture comprising an elongated member configured to allow passage of ambient light across a direction of elongation of the elongated member to a user'"'"'s eye. A display, such as an LCD, is supported by the support and is operative to provide an image. An eyepiece assembly is supported by the support fixture in proximity to the display to receive the image from the display and to direct the image to the user'"'"'s eye. The support fixture also defines an illumination path along the elongated member, and the display is located to receive illumination light on the illumination path from a light source.
