1. A display for providing an output image to an eye of a viewer, the display comprising:
(a) a first light-guide optical element (LOE) having a pair of parallel external surfaces;
(b) first and second image projector arrangements generating respectively first and second partial images, said first and second image projector arrangements being deployed to introduce the first and second partial images into said first LOE so as to propagate within said first LOE by internal reflection at said pair of external surfaces;
(c) a first coupling-out arrangement associated with said first LOE and configured for coupling out the first and second partial images so as to direct said first and second partial images towards the eye of the viewer;
(d) a second LOE having a pair of parallel external surfaces, said second LOE being deployed in overlapping relation with said first LOE;
(e) a third image projector arrangement generating a third partial image, said third image projector arrangement being deployed to introduce the third partial image into said second LOE so as to propagate within said second LOE by internal reflection at said pair of external surfaces; and
(f) a second coupling-out arrangement associated with said second LOE and configured for coupling out the third partial image so as to direct said third partial image towards the eye of the viewer,
wherein said first and second partial images provide non-overlapping subregions of the output image, and wherein said third partial image provides a central subregion of said output image partially overlapping with each of said first and second partial images, said first, second and third partial images contributing to a continuous output image as viewed by the eye of the viewer.
