摘要:
The present invention provides an 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. Further, the invention provides a plurality of light films with a thickness between 10 microns to 3mm and 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 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.
