Abstract
In some embodiments, a display system is provided. The display system comprises a plurality of light pipes and a plurality of light sources configured to emit light into the light pipes. The display system also comprises a spatial light modulator configured to modulate light received from the light pipes to form images. The display system may also comprise one or more waveguides configured to receive modulated light from the spatial light modulator and to relay that light to a viewer.
Claims36
A display system comprising:
- a plurality of light pipes;
- a plurality of light sources configured to emit light into the light pipes;
- and
- a spatial light modulator configured to modulate light received from the light pipes to form images,
- wherein each of the light pipes comprises first and second opposing ends and a sidewall extending from the first end to the second end,
- wherein the first end comprises a light input surface configured to receive light from an associated light source,
- wherein the second end comprises a light output surface configured to output light to the spatial light modulator, and
- wherein each light pipe is oriented to localize outputted light on a different location on the spatial light modulator than other light pipes.

A display system comprising:
- a partially transmissive reflector;
- a first light source;
- a first light pipe proximate to and configured to:
- receive light from the first light source;
- and
- direct the light from the first light source to the reflector in a first direction;
- a second light source;
- a second light pipe proximate to and configured to:
- receive light from the second light source;
- and
- direct the light from the second light source to the reflector in a second direction,
- wherein the partially transmissive reflector is configured to:
- transmit light from the first light source;
- and
- reflect light from the second light source,
- wherein each of the light pipes comprises first and second opposing ends and a sidewall extending from the first end to the second end,
- wherein the first end comprises a light input surface configured to receive light from an associated light source,
- wherein the second end comprises a light output surface configured to output light to the spatial light modulator, and
- wherein each light pipe is oriented to localize outputted light on a different location on the spatial light modulator than other light pipes.
