Abstract
A display system for near-eye applications may include multiple light sources and a geometric reflective waveguide (GRWG). The system may include a dichroic mirror configured to combine light from the multiple light sources, a folding optical element configured to guide and replicate the combined light, and an output optical element configured to direct the replicated light to an eyebox region. Various other display systems, waveguide configurations, and methods are also disclosed.
Claims20
A display system, comprising:
- a first light source that emits a first display light;
- a second light source that emits a second display light, wherein the first display light and the second display light comprise different light colors;
- a folding optical element;
- a dichroic mirror configured to:
- transmit the first display light to the folding optical element;
- and
- reflect the second display light to the folding optical element;
- and
- an output optical element configured to receive the first display light and the second display light from the folding optical element, wherein the output optical element is configured to direct the first display light and the second display light to an eyebox region.

A waveguide assembly, comprising:
- a folding optical element;
- a dichroic mirror configured to:
- transmit first display light from a first light source to the folding optical element;
- and
- reflect second display light from a second light source to the folding optical element;
- and
- an output optical element configured to receive the first display light and the second display light from the folding optical element, wherein the output optical element is configured to output the first display light and the second display light towards a display viewing region.
