Eyepieces for augmented reality display system

An augmented reality display system comprising:

• a first eyepiece waveguide comprising a first optically transmissive substrate;
• a first input coupling grating (ICG) region formed on or in the first eyepiece waveguide, the first ICG region being configured to receive a set of input beams of light corresponding to an input image having a corresponding field of view, and to couple a first subset of the input beams into the first optically transmissive substrate as a first set of guided beams, the first subset of the input beams corresponding to a first sub-portion of the field of view of the input image;
• a second eyepiece waveguide comprising a second optically transmissive substrate;
• and
• a second input coupling grating (ICG) region formed on or in the second eyepiece waveguide, the second ICG region being configured to receive at least a second subset of the input beams of light corresponding to the input image, and to couple the second subset of input beams into the second optically transmissive substrate as a second set of guided beams, the second subset of the input beams corresponding to a second sub-portion of the field of view of the input image,
• wherein the first and second sub-portions of the field of view are at least partially different but together include the complete field of view of the input image.
