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: The present disclosure describes a display system including a liquid crystal display panel and a light source emitting light capable of emitting light. A nonwoven diffuser element is disposed between the light source and the liquid crystal display panel. The polymeric nonwoven diffuser is non-orientated and has a fiber diameter of less than 50 micrometers, a fiber aspect ratio of length/diameter of greater than 5 and a basis weight in a range from 10 to 80 grams/meter2.
