A back reflector for a lightguide in a turning film backlight includes a prism film layer in direct contact with a reflective layer. The lightguide includes a light guiding region having a refractive index that is substantially spatially uniform. The reflective layer may be specular or diffuse and may include a multilayer polymeric film.

Backlight reflectors having a prismatic structure

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.

Liquid crystal displays with laminated diffuser plates

The present application is directed to a film they may be used as an adhesive for solar panels. For example, the present application is directed to a composition, for example an adhesive composition, comprising a low crystalline poly-alpha-olefin resin having and an alkoxysilane functional poly-alpha-olefin having a tensile strength of less than 500 MPa. The composition has a melt flow index of less than 30. The application is also directed to a panel comprising a front panel comprising a transparent barrier, a back panel and a photovoltaic material layer between the front panel and the back panel. An adhesive layer is between the front panel and the back panel, wherein the adhesive layer adheres the front panel to the back panel, and the adhesive layer comprises a low crystalline poly-alpha-olefin elastomer blended with an alkoxysilane functional polyolefin.

Solar panels with adhesive layers

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.

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.
