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.
Claims20
A wearable device, comprising:
- a light source configured to generate image light comprising a first bandwidth of light, the first bandwidth of light centered at a first frequency, the light source comprising a color source;
- a see-through display configured to present the image light to a user, the see-through display comprising a mirror configured to:
- direct the image light towards an eye of the user;
- and
- transmit environmental light, wherein:
- the image light does not comprise the environmental light,
- the environmental light comprises a second bandwidth centered at a second frequency, and
- the second frequency differs from the first frequency by less than a threshold frequency;
- and
- one or more filters, the one or more filters configured to apply a bandpass filter to an output of the color source to transmit the first bandwidth of light.
A method comprising:
- generating, via a light source of a wearable head device, image light comprising a first bandwidth of light, the first bandwidth of light centered at a first frequency, the light source comprising a color source;
- presenting, via a see-through display of the wearable head device, the image light to a user of the wearable head device, the see-through display comprising a mirror;
- directing, via the mirror, the image light towards an eye of the user;
- transmitting, via the mirror, environmental light, wherein:
- the image light does not comprise the environmental light,
- the environmental light comprises a second bandwidth centered at a second frequency, and
- the second frequency differs from the first frequency by less than a threshold frequency;
- and
- applying, via one or more filters of the wearable head device, a bandpass filter to an output of the color source to transmit the first bandwidth of light.
