Abstract

Aspects of the present disclosure relate a head-worn computer with a see-through display wherein computer content is presented to a user wearing the head-worn computer and through which the user sees a surrounding environment, wherein the see-through display generates image light comprised of narrow bandwidths of red, green and blue light and wherein the see-through display further includes a tristimulus notch mirror positioned to reflect the image light towards the user'"'"'s eye, and wherein the tristimulus notch mirror reflects less than a full width half max of the red image light.

Claims

1. A head-worn computer, comprising:

a see-through display wherein computer content is presented to a user wearing the head-worn computer and through which the user sees a surrounding environment,

wherein the see-through display generates image light comprising narrow bandwidths of red, green and blue light and wherein the see-through display further includes a tristimulus notch mirror positioned to reflect the image light towards the user'"'"'s eye, and

wherein the tristimulus notch mirror reflects less than a full width half max of the red image light.

2. The head-worn computer of claim 1, wherein the image light is generated with an emissive display.

3. The head-worn computer of claim 1, wherein the image light is generated with a reflective display.
