Abstract
A display system includes a substrate, an optically reflecting first film defining a plurality of first openings across a length and a width of the first major surface, pluralities of visible light emitting first devices, infrared light emitting second devices, and infrared light detecting third devices disposed in the first openings of the first film and mounted on the substrate, and an optically reflecting second film disposed on the pluralities of first, second, and third devices and the optically reflecting first film opposite the substrate. For a visible wavelength range and an infrared wavelength range, the first film has an average reflectance of greater than about 60% for each of the visible and infrared wavelength ranges, and the second film has an average reflectance of greater than about 60% for the visible wavelength range and an average transmittance of greater than about 50% for the infrared wavelength range.
