Abstract: A backlight includes a substrate, a plurality of light sources proximate the substrate, a first reflective layer on the substrate, and a plurality of patterned reflectors over the plurality of light sources. Each light source includes a size measured in a plane parallel to the substrate. Each patterned reflector is aligned with a corresponding light source and includes a thickness profile. The thickness profile includes a substantially flat section and a curved section extending from and surrounding the substantially flat section. The substantially flat section varies in thickness by no more than plus or minus 20 percent of an average thickness of the substantially flat section. The substantially flat section includes a size in a plane parallel to the substrate equal to or greater than the size of each light source.

Abstract: Novel backlighting units (BLU) for use with LCD panel are disclosed. Such BLUs have direct lighting configuration utilizing blue LED as light source and have quantum dots (QDs) integrated into the architecture of the BLU thus forming thin BLUs that efficiently convert the blue source light into white light while achieving enhanced uniformity in brightness of the white light.

Abstract: A backlight includes a substrate, a plurality of light sources, a reflective layer, a first diffuser plate, a second diffuser plate, and a color conversion layer. The plurality of light sources are proximate the substrate. The reflective layer is proximate the substrate. The first diffuser plate is over the plurality of light sources. The color conversion layer is between the first diffuser plate and the second diffuser plate.

Abstract: A backlight includes a substrate, a plurality of light sources, a light guide plate, and a plurality of rectangular reflectors including rounded corners. The plurality of light sources are proximate the substrate. The light guide plate is proximate the plurality of light sources. The plurality of rectangular reflectors including rounded corners are in a plane parallel to the light guide plate and each reflector corresponds to a light source.
