摘要： In a directly-illuminated liquid crystal display (LCD), for example an LCD monitor or an LCD-TV, a number of light management layers lie between the light source and the LCD panel to provide bright, uniform illumination. The light management layers, including, for example, a diffuser, a reflective polarizer and a brightness enhancing layer, are contained in a light management unit that is formed from two subassemblies. The two subassemblies each contain a substrate and are attached together so as to leave a gap between the two subassemblies. The diffuser is located in one of the subassemblies, and the other light management layers may be in either of the subassemblies, or may be disposed in the gap between the subassemblies.

摘要： In a directly-illuminated 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. The diffuser layer is attached to a substrate which is separate from the light source and the LCD panel, or may be attached to either the LCD panel or, when using a two dimensional light source, to the light source. The other light management layers may also be attached to the separate substrate or to the LCD panel or two-dimensional light source. High levels of illumination uniformity at the LCD may be achieved with a uniform (non-patterned) diffuser, even with relatively low levels of diffusion, when the diffuser is used with a brightness enhancing layer.

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 members on a first side of the light diverting layer facing the diffuser. Surfaces of the light diverting members 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 members spread the illumination light so as to be more uniform. Different light diverting members can have different apex angles. Also, different sides of a light diverting member can have best fit centers of curvature that are non-coincident.

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. An optical sheet is disposed over the LEDs. 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 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.
