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 multilayer optical film includes a plurality of optical repeat units. Each of the optical repeat units includes at least four sequentially arranged first through fourth layers including first and third layers having respective f-ratios f1 and f3. The optical film has a first order reflection band having a reflection peak height Rp1 and any second order reflection band has a reflection peak height Rp2, where Rp1/Rp2≥5. Rp1/Rp2 may remain at least 5 when changing at least one of the f-ratios f1 and f3 continuously by 0.2. A thickness of each of the second and fourth layers can be less than a thickness of each of the first and third layers by at least a factor of 2, or a thickness of a same one of the first and third layers can differ from a thickness of each other layer by at least a factor of 2.5.

Abstract: A multilayer optical film includes a plurality of alternating polymeric first and second layers and optically absorptive material dispersed in at least one layer of the multilayer optical film. The multilayer optical film has an average optical transmittance in a visible wavelength range extending from about 450 nm to about 650 nm of about 0.5% to about 40%, an average optical reflectance in the visible wavelength range of less than about 40%, and an average optical reflectance in an infrared wavelength range extending from about 850 nm to about 1200 nm of greater than about 60%. For illuminant D65 light incident on the multilayer optical film, the multilayer optical film reflects and transmits portions of the incident light as reflected and transmitted lights that have color shifts below specified limits in a CIE L*a*b* color space. A glass laminate includes the multilayer optical film disposed between glass layers.

Abstract: An optical film includes a plurality of polymeric layers. A plot of an average layer thickness versus a layer number of the polymeric layers includes a knee region separating a left region including at least N1 sequentially arranged polymeric layers where the polymeric layers have lower layer numbers from a middle region including at least N2 sequentially arranged polymeric layers where the polymeric layers have higher layer numbers. N1 is greater than about 50 and N2 is greater than about 10. A linear fit to the at least N1 sequentially arranged polymeric layers in the left region has a positive linear slope having a magnitude of greater than about 0.04 nm per layer number, and a linear fit to the at least N2 sequentially arranged polymeric layers in the middle region has a negative linear slope having a magnitude of greater than about 0.05 nm per layer number.
