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.

Backlights including patterned diffusers and wavelength selective reflectors

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.

Backlights including patterned reflectors

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.

Backlight including patterned reflectors, diffuser plate, and method for fabricating the backlight

The present disclosure relates to substrates having laser-induced scattering features located either on the surface of the substrate or within the substrate, along with methods of making such scattering substrates. The disclosed scattering substrates provide improved light extraction properties and may be useful in a variety of applications, such as lighting and electronic displays.
