Summary:Display systems with a single plate optical waveguide and independently adjustable micro display arrays and related methods are provided. A method includes coupling: a first light portion received from the first micro display array to a first input grating region of the optical waveguide, a second light portion received from the second micro display array to a second input grating region of the optical waveguide, and a third light portion received from the third micro display array to a third input grating region of the optical waveguide. The method further includes directing: a first diffracted portion of the first light portion to a first expansion grating, a second diffracted portion of the second light portion to a second expansion grating, and a third diffracted portion of the third light portion to a third expansion grating. The method further includes using a single output grating outputting combined light.
