摘要： A directly illuminated display unit has a display panel and one or more light sources disposed behind the display panel. A diffuser is disposed between the light source unit and the display panel and a light diverting layer is disposed between the one or more light sources and the diffuser. The light diverting layer has light diverting elements on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting elements are disposed at more than one angle relative to a normal to the light diverting layer and also include one or more sharp changes of surface slope. The light diverting elements spread the illumination light so as to be more uniform. Different light diverting elements can have different apex angles. Also, different sides of a light diverting element can have best fit centers of curvature that are non-coincident.

摘要： Light directing film (100) is disclosed. The light directing film includes a structured major surface (110) that includes a plurality of microstructures (150) extending along a first direction (142) and a plurality of elevated portions (160) disposed on the plurality of microstructures. The number density of the elevated portions across the light directing film is D. Each elevated portion includes a leading edge (162) and a trailing edge (164) along the first direction. The light directing film can be divided into a plurality of same size and shape grid cells that form a continuous two-dimensional grid. The area of each grid cell is approximately 1/D. Each of at least 70% of the grid cells includes a single leading edge (162) of an elevated portion (160).

摘要： Lighting devices are disclosed that include a light source, a circular reflective polarizer optically coupled to the light source, a back reflector configured and disposed to reflect light that has been reflected by the circular reflective polarizer back toward the input surface thereof, one or more optical elements having a total non-zero retardance Rs and disposed between the circular reflective polarizer and the back reflector, and a customized retarder. The customized retarder has a retardance Rc such that a total retardance of the one or more optical elements and the customized retarder, Rs + Rc, approaches n?/2. The one or more optical elements, the customized retarder and the back reflector are characterized by a total depolarization of no more than 66%. Display devices including such lighting devices are also disclosed.

摘要： In a liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management films (120), including a diffuser layer (122), lie between the light source (112) and the LCD panel (102) to provide bright, uniform illumination. In some embodiments, the diffuser layer is attached to the lower side of the LCD panel. In other embodiments, it is formed as a layer on a substrate of a material such as glass, or is attached to the front surface of the light source. 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.

摘要： A light emitting diode (LED) array comprises an array of LEDs mounted to a substrate. The LEDs emit light in a direction generally perpendicular to the substrate (308). An optical sheet is disposed over the LEDs (320). At least a portion of light entering one side of the optical sheet from the LEDs is guided within the optical sheet in a direction generally parallel to the substrate. Light extraction features (324) direct light from the optical sheet in a generally forward direction. Such an array is useful for several applications, including space lighting, direct information display and backlighting of liquid crystal displays. The light spreading effect of the optical sheet reduces the amount of black space between LED pixels.
