摘要： 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.

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： 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.
