20130316137 | BRIGHTNESS ENHANCING FILM COMPRISING NANOCOMPOSITE STRUCTURE HAVING IMPROVED CRACK RESISTANCE - Microstructured films such as brightness enhancing films. The microstructured film has a polymerized structure comprising the reaction product of the polymerizable resin composition (e.g. having a refractive index of at least 1.58). The cured nanocomposite (e.g. structure) can exhibit improved crack resistance. In some embodiments, the flexibility is expressed in terms of a cylindrical mandrel bend test property (e.g. a mandrel size to failure of less than 6 mm or a mandrel size to failure according to the equation D=1000(T/0.025−T) wherein T is the thickness in millimeters of a (e.g. preformed base layer). In other embodiments, the flexibility is expressed in terms of a tensile and elongation property (e.g. a tensile strength at break of at least 25 MPa and an elongation at break of at least 1.75%). | 11-28-2013 |
20130323467 | HIGH REFRACTIVE INDEX INORGANIC OXIDE NANOPARTICLES COMPRISING SURFACE TREATMENT AND POLYMERIZABLE RESIN - Microstructured films comprising surface modified inorganic oxide particles and polymerizable resins are described. | 12-05-2013 |
20150317923 | INCONSPICUOUS OPTICAL TAGS AND METHODS THEREFOR - Tags are made from optical films to provide a pattern that is inconspicuous to ordinary observers, but that is detectable by a camera or other imaging device. The pattern is provided by first and second portions of a patterned layer, the first portions selectively filtering at least a portion of blue visible light from other visible light wavelengths. Filtering in the portion of the blue region helps make the pattern inconspicuous. The tags may also include an indicia layer configured to mark a location of the pattern, and a contrast enhancing layer disposed behind the patterned layer and configured to enhance a contrast of the pattern. In some cases, the first portions of the patterned layer may filter optical wavelengths other than blue, such as near-infrared light. The pattern may comprise machine-readable information, e.g., a linear bar code or a 2-D bar code. Associated methods and systems are also disclosed. | 11-05-2015 |
20150325813 | EMISSIVE DISPLAY WITH HYBRID POLARIZER - An emissive display comprising an OLED, a first birefringent reflective polarizer, a second birefringent reflective polarizer optically between the OLED and the first birefringent reflective polarizer, a first linear absorbing polarizer having a contrast ratio of less than 100:1 optically between the first birefringent reflective polarizer and the second birefringent reflective polarizer, a second linear absorbing polarizer having a contrast ratio of less than 100:1, where the first birefringent reflective polarizer is optically between the second linear absorbing polarizer and the first linear absorbing polarizer, and a structured optical film optically between the OLED and the second birefringent reflective polarizer. | 11-12-2015 |
20150325816 | EMISSIVE DISPLAY WITH REFLECTIVE POLARIZER - An emissive display includes an OLED, a linear polarizer, a reflective polarizer optically between the OLED and the linear polarizer, and a structured optical film optically between the OLED and the reflective polarizer. | 11-12-2015 |
