1. A waveguide assembly, comprising:
a transparent waveguide substrate;
an in-coupler directly optically coupled to one end of the transparent waveguide substrate;
a parallelepiped prisms array structure directly optically coupled to a first horizontal side of the transparent waveguide substrate, the parallelepiped prisms array structure for extracting from the transparent waveguide substrate light that has been in-coupled by the in-coupler; and
wherein the light that has been extracted is directed by the parallelepiped prisms array structure toward a viewer's eye as a first image.
