1. A hybrid display system comprising:
a field display having a monocular field of view of at least 40 degrees, the field display comprising a field display element generating a field image and a waveguide;
a foveal display comprising:
a foveal display element generating a foveal image having a monocular field of view of between 1 and 20 degrees;
a positioning system to position the foveal image within a scannable field of view spanning greater than 20 degrees; and
intermediate optics between the foveal display element and the positioning system to generate a virtual image, wherein the virtual image is directed toward a user's eye by the positioning system; and
a fully or partially transparent optical element to direct the foveal image to the user's eye.
