Abstract
A display system includes a light pipe including elongated surfaces and an input coupler. The light pipe is configured to provide an image received by the input coupler and expand the image in a first direction through one of the elongated surfaces. The display also includes a waveguide including an output grating, a first surface, a second surface, and a side surface. The first surface and the second surface have a larger area than the side surface, the output grating being configured to provide the image expanded in a second direction. The second direction is different than the first direction. The image enters the waveguide from the one of the elongated surfaces at the side surface.
