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.
Claims44
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.
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.
A method for forming an optical device, the method comprising:
- forming a light pipe with a roughened sidewall surface;
- coupling the light pipe to a light emitter;
- and
- coupling an assembly comprising the light pipe and the light emitter to a spatial light modulator.
The method of claim 38, wherein coupling the light pipe to the light emitter comprises coupling light input surface of the light pipe three plurality of light emitters.
