20100246016 | GLASS HAVING ANTI-GLARE SURFACE AND METHOD OF MAKING - A glass article having an anti-glare surface. The anti-glare surface has a distinctness-of-reflected image of less than 95, and a haze of less than or equal to 50%.

20110043719 | OPTICALLY TRANSMISSIVE COMPOSITE FILM FRAME - Optical display backlight assemblies having a transmissive optical film affixed to a frame which at least partially surrounds a backlight, are disclosed. The transmissive optical film can provide an increased bending resistance to the frame. The increase in bending resistance of the frame also increases the bending resistance of a display which incorporates the backlight assemblies. The optical film can be in tension after being affixed to the frame, and the tension in the film also can result in a flatter film surface with less sag. The film can be placed in tension prior to being affixed to the frame, the frame can be elastically distorted prior to affixing the film to impart tension to the film, or the film can develop tension by shrinkage after being affixed to the frame. | 02-24-2011 |

20110062849 | GLASS AND DISPLAY HAVING ANTI-GLARE PROPERTIES - A glass article that is ion-exchangeable and has at least one roughened surface. The roughened surface has a distinctness-of-reflected image DOI of less than 90 when measured at an incidence angle of 20°. A pixelated display system that includes such a glass article is also provided. | 03-17-2011 |
20110096395 | COLOR SHIFTING MULTILAYER POLYMER FIBERS AND SECURITY ARTICLES CONTAINING COLOR SHIFTING MULTILAYER POLYMER FIBERS - Polymer fibers are formed with concentric alternating layers of different polymer materials. The layers pairs have cross-sectional thicknesses selected for reflecting light at a selected visible wavelength. A cross-sectional dimension of the core is at least ten times an average of the selected thicknesses of the alternating layers. Some articles formed by the fibers are formed by attaching one fiber to another: the color of the fibers at the point of attachment is different from the colors of the fibers elsewhere. The fibers may be deformed to change its color properties by elongating the cross-section of the polymer fiber along a first cross-sectional axis. In some embodiments, the fibers are polarization sensitive. | 04-28-2011 |
20110102891 | LOW LAYER COUNT REFLECTIVE POLARIZER WITH OPTIMIZED GAIN - Multilayer reflecting polarizing films are disclosed having increased in-plane refractive index differences between adjacent microlayers along both the pass and block axis, and having negative refractive index differences between adjacent microlayers along the thickness or z-axis. Major front and back surfaces of the film exposed to air provide a Fresnel reflectivity component to the pass axis reflectivity, and the microlayers provide a microlayer component to the pass axis reflectivity, such microlayer component preferably having a reflectivity of p-polarized light that increases with incidence angle faster than the Fresnel reflectivity component decreases so as to substantially avoid off-axis gain peaks for p-polarized light. The films preferably utilize a relatively small total number of microlayers, arranged in a single coherent stack with monotonic optical repeat unit thickness profile, and at least some microlayers preferably include polyethylene naphthalate or a copolymer thereof. | 05-05-2011 |
20110103036 | OPTICAL FILM - An optical film that includes a reflective polarizer and a stretched polymer film is disclosed. The stretched polymer film is laminated to the reflective polarizer, and the stretched polymer film exhibits a refractive index symmetry point at an angle of incidence in air of at least about 60 degrees in a plane of incidence parallel to a direction of greatest stretch. | 05-05-2011 |
20110261584 | SYSTEMS AND METHODS FOR CONTROLLING BACKLIGHT OUTPUT CHARACTERISTICS - A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films. | 10-27-2011 |

20080274293 | Spiral Multilayer Fibers - A spiral wound fiber that includes birefringent interfaces is useful in different optical devices. One type of wound fiber includes at least first and second material layers. At least one of the layers is polymeric and at least one of the layers is birefringent. The spiral wound fiber may be used alone, or in an optical device. Such an optical device can include the fiber embedded within a matrix or attached to a substrate. The spiral wound fiber can be made by rolling a stack of at least two layers, by coextruding the two layers or by coating a rotating form. | 11-06-2008 |

20090251776 | MULTILAYER POLARIZING FIBERS AND POLARIZERS USING SAME - A polarizing film is made of multilayer polarizing fibers embedded within a matrix. The fibers are formed with layers of at least a first and a second polymer material. Layers of the first polymer material are disposed between layers of the second polymer material. At least one of the first and second polymer materials is birefringent.

20110149554 | STRUCTURED COMPOSITE OPTICAL FILMS - Optical films having structured surfaces are used, inter alia, for managing the propagation of light within a display. As displays become larger, it becomes more important that the film be reinforced so as to maintain rigidity. An optical film of the invention has a first layer comprising inorganic fibers embedded within a polymer matrix. The first layer has a structured surface to provide an optical function to light passing therethrough. The film may have various beneficial optical properties, for example, light that propagates substantially perpendicularly through the first layer may be subject to no more than a certain level of haze or light incident on the film may be subject to a minimum value of brightness gain. Various methods of manufacturing the films are described. | 06-23-2011 |
