Large-gamut color and spectral display using sub-wavelength gratings
  DOI :  10.2352/ISSN.2169-2629.2017.32.2  Published OnlineNovember 2016

As content creation, editing, approval, prototyping, manufacturing and consumption become ever more distributed, the ability to display a broad variety of colors becomes increasingly more important. Displays that use RGB filters or even backlights cannot span all spectra or even just colors that occur in nature. To improve the accuracy of spectral and color reproduction, there have been attempts to include additional color primaries in displays. Existing solutions, however, impact cost, scalability, or spatial resolution and are predominantly applicable to projections system. We propose an approach based on combining diffraction gratings extractors (Fattal et al., 2013) and the HANS imaging pipeline (Morovič et al., 2011) initially developed for printing. This combination offers access to a very large color and spectral gamut with the same backlights as commercially used today.
