US 11,539,924 B2 · Multiple projector-enabled content targeting using diffraction grating

Abstract

Multiple projector-enabled content targeting using diffraction grating is provided. A projector of a plurality of projectors in a display device is selected to project a particular color of a plurality of different colors at a predefined intensity to a content slot in a set of content slots via a corresponding diffraction grating to provide different content in full color images to respective viewers of a set of viewers at different viewing angles relative to the display device simultaneously. The different content is projected in the full color images to the respective viewers at the different viewing angles simultaneously using each particular projector of the plurality of projectors to project its particular color of the plurality of different colors at the predefined intensity to each particular content slot of the set of content slots via each corresponding diffraction grating.
