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 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.
