Claim Text:
1. A head-worn computer display, comprising: a. a reflective display including a plurality of multi-positional micro-mirrors; b. an illumination system positioned at an angle of greater than 90 degrees from a front surface of the reflective display, wherein the illumination system is adapted to produce illumination light and project the illumination light in a direction away from the reflective display and towards a first side of a reflective surface such that the reflective surface reflects the illumination light in a direction towards the reflective display to generate image light; c. image light delivery optics with an eyebox wherein the image light is provided to a user's eye; and d. a processor adapted to control the reflective display such that each of the plurality of multi-positional micro-mirrors is positionally controlled between an on-state and an off-state to reflect the illumination light in a selected direction, wherein the selected direction comprises a first selected direction and a second selected direction, wherein the selected direction is selected depending on the state of the micro-mirrors, wherein the first direction is in-line with the image light delivery optics adapted to present on-state light as the image light to the user's eye in the eyebox; and wherein the second direction is in-line with a dark-light trap at a side of the image light delivery optics adapted to capture at least a portion of off-state light and prevent the at least a portion of off-state light from entering the eyebox.
