DISPLAY SYSTEM WITH MEANS FOR GENERATING MULTIPLE EXIT-PUPIL IMAGES IN AN EXPANDED EXIT PUPIL

摘要

A display system (100) includes a diffraction grating (112) that generates exit-pupil images (102), where one of the exit-pupil images has a first intensity and the remaining exit-pupil images each have or approximately have a second intensity that is less than the first intensity. The system also includes a filter (114) that attenuates the intensity of the one exit-pupil image. In one example, the filter attenuates the Oth -order exit-pupil image so that all of the exit-pupil images have the same or approximately the same intensities.
