Abstract

The disclosed projector device may include (1) a first monochromatic emitter array having a plurality of emitters of a first color disposed in a two-dimensional configuration and (2) a second monochromatic emitter array having a plurality of emitters of a second color disposed in a two-dimensional configuration. The first and second monochromatic emitter arrays may be configured to emit images of the first and second colors into a waveguide configuration, and the first color may be different than the second color. Associated display systems and methods are also provided.

Claims (14)

1. A projector device comprising:

a first monochromatic emitter array having a plurality of emitters of a first color;

a second monochromatic emitter array having a plurality of emitters of a second color; and

a third monochromatic emitter array having a plurality of emitters of a third color, wherein the first, second, and third monochromatic emitter arrays are configured to emit images of the first, second, and third colors into a waveguide configuration, the waveguide configuration comprising:

a first waveguide member coupling the first image of the first color into a first waveguide member body, and

a second waveguide member coupling both the second image of the second color and the third image of the third color into a second waveguide member body, wherein the first waveguide member comprises a decoupling element configured to direct light of the first color through the second waveguide member.

2. The projector device of claim 1 , further comprising:

a support structure to which the first and second monochromatic emitter arrays are secured such that the first and second monochromatic emitter arrays are configured to emit images of the first and second colors along a same direction into the waveguide configuration.

3. A display system comprising:

a first monochromatic emitter array having a plurality of emitters of a first color configured to produce a first image of the first color; and

a second monochromatic emitter array having a plurality of emitters of a second color configured to produce a second image of the second color, wherein the first and second monochromatic emitter arrays are configured to emit the images of the first and second colors into a single waveguide.

4. The display system of claim 3 , wherein the single waveguide is configured to provide image light to both eyes of a user.

5. The display system of claim 3 , wherein the single waveguide comprises first and second coupling elements configured to couple the first and second images into the single waveguide at different positions.

6. The display system of claim 3 , further comprising a third monochromatic emitter array having a plurality of emitters of a third color configured to produce a third image of the third color, wherein the first, second, and third monochromatic emitter arrays are configured to emit the images of the first, second, and third colors into a single waveguide, the single waveguide comprising first, second, and third coupling elements configured to couple the first, second, and third images into the single waveguide at different positions.
