Abstract
Single-sheet waveguide combiners having increased field-of-view for multiple colors by enabling separate action on different colors without creating spurious paths are provided. A waveguide includes a first region including an in-coupler (IC) grating for a first color; a second region including an IC grating for a second color and a third color; a third region including an out-coupler (OC) grating for the first color and an eye-pupil-expander (EPE) grating for the second color and the third color; a fourth region including an EPE grating for the first color; and a fifth region including an OC grating for the second color and the third color and an EPE grating for the first color, wherein the fifth region at least partially overlaps with the third region.
