Claim Text:
1. An optical system for a head-worn computer, comprising: a polarized light source positioned within the head-worn computer and adapted to project polarized light towards a partially reflective partially transmissive surface such that the polarized light reflects through a field lens and towards a reflective display forming image light, wherein the polarized light is converted to a different polarization state after reflecting off a surface of the reflective display, wherein the image light is then transmitted through the field lens and then through the partially reflective partially transmissive surface to an eye image display optical system adapted to present the image light to an eye of a user wearing the head-worn computer, and wherein the reflective display is a monochrome reflective display and the polarized light source provides sequential illumination of red, green and blue light to provide a perceived full color image to the eye of the user.
