Abstract: A display system for sensing a finger of a user applied to the display system includes a display panel; a sensor for sensing the finger; a sensing light source configured to emit a first light having a first wavelength W1; and a reflective polarizer disposed between the display panel and the sensor. For a substantially normally incident light, an optical transmittance of the reflective polarizer versus wavelength for a first polarization state has a band edge such that for a first wavelength range extending from a smaller wavelength L1 to a greater wavelength L2 and including W1, where 30 nm?L2?L1?50 nm and L1 is greater than and within about 20 nm of a wavelength L3 corresponding to an optical transmittance of about 50% along the band edge, the optical transmittance has an average of greater than about 75%.

Abstract: A thermoplastic acrylonitrile containing copolymer/lignin blend, e.g., thermoplastic acrylonitrile-butadiene-styrene copolymer/lignin blend, is provided, whereas the blend comprises (i) an amount of thermoplastic acrylonitrile containing copolymer (e.g., acrylonitrile-butadiene-styrene copolymer); (ii) an amount of lignin; (iii) an amount of compatibilizing agent, such as phthalic anhydride, capable of imparting improved ductility and impact strength to the resultant blend and (iv) optionally an amount of at least one additive to impart specific properties including, but not limited, to resistance to ultraviolet radiation, resistance to oxidation, flame retardance, color, surface friction, or surface static charge accumulation. Methods of improving impact strength and/or ductility of, for example, a thermoplastic acrylonitrile-butadiene-styrene copolymer/lignin blend and articles made therefrom are also disclosed.
