Abstract: An optical construction includes a reflective polarizer and an optically diffusive film disposed on the reflective polarizer. The reflective polarizer includes an outer layer including a plurality of first particles partially protruding from a first major surface thereof to form a structured major surface. A first optically diffusive layer is conformably disposed on the structured major surface. The optically diffusive film includes a second optically diffusive layer including a plurality of nanoparticles dispersed therein, and a structured layer including a structured major surface. For a substantially normally incident light and a visible wavelength range from about 450 nm to about 650 nm and an infrared wavelength range from about 930 nm to about 970 nm, the second optically diffusive layer has an average specular transmittance Vs in the visible wavelength range and an average specular transmittance Is in the infrared wavelength range, where Is/Vs≥2.5.

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 mn≤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 scrubbing article including a substrate, a stain release coating and a texture layer. The stain release coating is applied to the substrate and is present over a at least a major surface of the substrate, and the texture layer is formed over the stain release coating opposite the substrate. In some embodiments, the texture layer is printed on to the stain release coating. The substrate can assume various forms, such as nonwoven, fabric (e.g., woven or knitted), foam, film and sponge material or combinations thereof.

Abstract: A scrubbing article including a substrate and a UV treated texture layer on a surface of the substrate. The substrate is formed from a single layer of foam or sponge material having a thickness that is conducive to handling or holding. The UV treated texture layer is a resin-based material forming a textured abrasive layer on the surface of the substrate.

Abstract: An optical construction (100) includes a lightguide (102), a transmissive reflector (112), and an optical sensor (114). The lightguide (102) includes a first major surface (104) and a second major surface (106) opposite to the first major surface (104). The first major surface (104) includes a first portion (108) and an adjoining second portion (110). The transmissive reflector (112) is disposed adjacent to the first major surface (104) of the lightguide (102). The optical sensor (114) is disposed adjacent to the transmissive reflector (112) opposite to the lightguide (102). The optical sensor (114) is aligned with the first portion (108) of the first major surface (104) of the lightguide (102), such that the optical sensor (114) receives at least a portion of light passing through the first portion (108) of the first major surface (104) and transmitted by the transmissive reflector (112). The optical construction (100) further includes an enclosed gap (116) disposed between the first portion (108) of the first major surface (104) of the lightguide (102) and the transmissive reflector (112).
