Briefly, in accordance with one or more embodiments, a display screen for a scanned beam display system comprises an exit pupil expander comprising a reflective layer to reflect an incoming beam from a scanned beam projector to an eyebox. Exit numerical aperture cones emanating from the exit pupil expander resulting from the reflected incoming beam are angularly redirected toward an eyebox disposed near an image plane to result in at least partially overlapping zeroth-order diffraction pattern from multiple spots on the exit pupil expander.
