Abstract: An optical film includes a plurality of polymeric layers, such that a transmittance of the polymeric layers versus wavelength includes: a left band edge separating a wavelength range where the polymeric layers has a transmittance of greater than about 60% from a wavelength range where the polymeric layers has a reflectance of greater than about 80%; and a mid-wavelength corresponding to a transmittance of about 50% along the left band edge. A display system includes a light converting film having green and red emission spectra including respective green and red emission peaks with respective green and red full width at half maxima (FWHMs); and includes the optical film disposed on the light converting film. For each of the FWHMs, the mid-wavelength is less than or equal to a shortest wavelength of the FWHM or greater than the shortest wavelength by no more than about 30% of the FWHM.

Abstract: An article (100) for a display device includes a diffraction grating film (102), a first optically clear adhesive layer (120), and a second optically clear adhesive layer (130). The diffraction grating film includes a base layer (104) and a plurality of microstructures (106) projecting from the base layer. The base layer defines a non-structured surface of the diffraction grating film and the plurality of microstructures define a structured surface of the diffraction grating film opposite to the non-structured surface. The first optically clear adhesive layer is disposed on the structured surface of the diffraction grating film. The second optically clear adhesive layer is disposed on the non-structured surface of the diffraction grating film.
