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%. In one embodiment, the glass article further includes a smudge-resistant surface disposed on the anti-glare surface. Methods of making the glass article and anti-glare surface are also described. | 09-30-2010 |
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 |
20110051047 | HOLLOW BACKLIGHT WITH STRUCTURED FILMS - A backlight ( | 03-03-2011 |
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 |
