Abstract: A backlight unit is provided for a liquid crystal display (LCD) unit in a display device. The backlight unit includes a light guide plate (LGP) and a first light source. The light guide plate has two major surfaces and a first side wall surface between the two major surfaces. The first light source is contact with or in proximity to the first wall surface of the light guide plate and optically coupled with the light guide plate. The light guide plate has a dimension such as length greater than a dimension such as length for the LCD unit. The first light source has a dimension such as length equal to or greater than the dimension such as length for the LCD unit.

Abstract: A backlight includes a substrate, a plurality of light sources, a reflective layer, a light guide plate, a pattern of light extractors, a plurality of patterned reflectors, and a diffusive layer. The plurality of light sources are proximate the substrate. The reflective layer is on the substrate. The light guide plate is proximate the plurality of light sources. The pattern of light extractors is on the light guide plate. The plurality of patterned reflectors are on the light guide plate. Each patterned reflector is aligned with a corresponding light source. The diffusive layer is on the light guide plate.

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.
