Abstract: 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.

Abstract: In one embodiment, the invention provides backlight comprising a front reflector (102) and a back reflector (104) disposed to form a hollow light cavity (106) with a first light source (108) proximate one end of the front reflector (102) and having a tilt angle (110) of from 5° to 90°, and a first asymmetric light collimator (116) extending between at least the first light source (108) and the back reflector (104) for directing light from the first light source (108) into the hollow light cavity (106).

Abstract: In a liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films, including a diffuser layer, lie between the light source and the LCD panel to provide bright, uniform illumination. In some embodiments, the diffuser layer is attached to the lower side of the LCD panel. Some, or all, of the light management layers may be attached together as a laminated stack of films. In some embodiments, the diffuser layer is formed with a recessed region on one side and another optical film positioned within the recessed region.

Abstract: The present disclosure is directed to optical devices including a light source and an optical film having a first surface disposed to receive light from the light source and a second surface facing away from the light source. The second surface includes a two-dimensional array of closely packed substantially hemispherically-shaped structures. In some implementations of the present disclosure, the optical film further includes a substrate portion having an optical characteristic different from optical characteristics of the second surface comprising the two dimensional array.

Abstract: Optical films are disclosed, which have a structured surface including a plurality of concave pyramid-shaped structures, each structure having a base including at least two first sides and at least two second sides. In addition, optical devices are disclosed that incorporate the optical films, for example, such that a first surface of the optical film is disposed to receive light from a light source and the structured surface faces away from the light source.

Abstract: An optical article has a substrate including a reflective polarizing element preferentially reflecting light having a first polarization state and preferentially transmitting light having a second polarization state and a beaded layer disposed on the substrate. The beaded layer includes transparent binder and a plurality of transparent beads dispersed therein. A normal angle gain of the optical article with the beaded layer is increased when compared to a normal angle gain of the same optical article but without the beaded layer.

Abstract: An optical device such as an LCD has a package of optical films positioned between a backlight and a display panel for enhancing the optical performance of the device. The package of optical films includes a first layer and a third layer and a second layer disposed between the first and third layers. The second layer is smaller than the first layer, so that the second layer covers a first region of the first layer but not a second region of the first layer. The third layer is attached to the second region of the first layer. In some embodiments the first layer has a structured surface facing the second layer. In other embodiments, the second layer has a structured surface facing the third layer. In other embodiments, both the first and second layers have structured surfaces facing the third layer.

Abstract: Directly illuminated liquid crystal display (LCD) units include an LCD panel, a backlight cavity, an optical film stack located between the LCD panel and the backlight cavity, and a supporting structure.

In some cases, the supporting structure includes a flexible support such as a film, a filament, or an array of filaments that are held taut in at least one dimension. In some cases, the supporting structure includes a rigid elongated support that covers only a portion of a useful area of the film stack.
