Light guide display assembly for providing expanded field of view

A device, comprising:

• one or more light guides;
• a first in-coupling element configured to couple a first light having a first input field of view (“FOV”) into a first light guide;
• a second in-coupling element configured to couple a second light having a second input FOV into a second light guide;
• a first out-coupling element configured to couple the first light out of the first light guide as a first output light having a first output FOV;
• and
• a second out-coupling element configured to couple the second light out of the second light guide as a second output light having a second output FOV substantially non-overlapping with the first output FOV,
• wherein a combination of the first output FOV and the second output FOV is larger than at least one of the first output FOV or the second output FOV,
• wherein the first light guide and the second light guide are a same single light guide,
• wherein the first in-coupling element and the second in-coupling element are stacked together or disposed side by side at the single light guide, and
• wherein the first out-coupling element and the second out-coupling element are stacked together or disposed side by side at the single light guide.

A method, comprising:

• coupling a first light having a first input field of view (“FOV”) into a first light guide and coupling the first light out of the first light guide as a first output light having a first output FOV;
• and
• coupling a second light having a second input FOV into a second light guide and coupling the second light out of the second light guide as a second output light having a second output FOV substantially non-overlapping with the first output FOV,
• wherein a combination of the first output FOV and the second output FOV is larger than at least one of the first output FOV or the second output FOV, and
• wherein the first light and the second light have orthogonal polarizations.
