Waveguide for generating overlapping images in a display module

A display apparatus, comprising:

• a display module comprising a plurality of optical output ports, each configured to project optical light, and a light engine configured to generate the optical light for each of the plurality of optical output ports;
• and
• a waveguide comprising a plurality of optical input ports each optically coupled to one of the plurality of optical output ports of the display module to receive the optical light representing a left portion and a right portion of a binocular field-of-view, wherein the waveguide further comprises:
• at least one optical output port configured to output at least a modified portion of the optical light;
• and
• a plurality of transmission channels, each coupled to one of the plurality of optical input ports and configured to transmit the optical light from a respective optical input port to the at least one optical output port to generate a binocular image in the at least one optical output port,
• wherein the plurality of transmission channels are arranged to cause the optical light diffracted from at least a first one of the plurality of transmission channels to partially overlap, at the at least one optical output port, with the optical light diffracted from at least a second one of the plurality of transmission channels.
