The present invention provides a multilayered integrated backlight illumination assembly for an LCD display comprising a substrate for providing structural and functional support to the assembly, a bottom reflector provided on the substrate and a plurality of solid state light sources provided in an opening of the bottom reflector for providing a point light source. The invention further provides a plurality of primary light films having light redirecting areas provided between the plurality of solid state light sources for redirecting and spreading the point light source to a uniform plane of light, a plurality of secondary light films having light redirecting areas provided between the plurality of solid state light sources for redirecting and spreading the point light source to a uniform plane of light and a binding means for binding the primary and secondary light films together. Further, the invention provides a top diffuser for diffusing the uniform plane of light and wherein the plurality of light films has a thickness between 0.1 mm to 1.0 mm and a bending stiffness between 50 to 1200 millinewtons.

Multilayered integrated backlight illumination assembly

A solid waveguide comprises opposite TIR surfaces further comprising:

Elongated illuminators configuration for LCD displays

A backlight apparatus for directing light toward a display panel and the resulting display device comprises an elongated illuminator that is disposed to direct light towards the display panel and a light diffusing element for uniformizing the light redirected from the two or more elongated illuminators to provide backlight illumination. Such an apparatus provides a more even light distribution to the display.

LCD display backlight using elongated illuminators

The invention relates to a base comprising a closed cell foam core sheet having a closed cell foam layer with a density gradient between the center of the core and the surfaces of the core. The invention also relates to a method of making such a base by adding a first concentration of a first blowing agent to a first polymer to form a first mixture, adding a second concentration of a second blowing agent to a second polymer to form a second mixture, and extruding the mixtures to form the closed cell foam core sheet. The invention also relates to a method of making such a closed cell foam core sheet base comprising the steps of adding a blowing agent to a polymer to form a mixture, melting the mixture, extruding the mixture from a die, and rapidly quenching the mixture against a high heat transfer surface.

Foam core imaging element with gradient density core

A backlight apparatus for directing light toward a display panel and the resulting display device comprises a solid lightguide comprising opposite TIR surfaces, containing a desired pattern of light redirecting surface features located between the TIR surfaces and interrupting one of the TIR surfaces, the features having a refractive index differing from that of the solid material of the light guide. Such an apparatus provides a more even light distribution to the display.
