Methods, systems, devices, and apparatuses are described. A variable diffuser pattern (VDP) may be applied to a substrate and configured to diffuse light from a light source (e.g., a light emitting diode (LED)), where the diffused light may have luminance uniformity and color uniformity measured at various distances from the light source. The VDP may include two or more different materials (e.g., different nanoparticle inks), and each material may have unique spectral reflectance and transmittance properties. For example, a first material may produce relatively more backscatter in red light wavelengths (e.g., as compared to blue and green light wavelengths), and a second material may produce relatively increased backscatter in blue light wavelengths (e.g., as compared to red and green light wavelengths). The VDP including the first and the second material may provide controlled scattering of light from the light source, resulting in uniform luminance and color of the scattered light.

Embodiments of a deadfront article for a display are disclosed herein. The deadfront article includes a cover structure having: an inner surface; an outer surface opposite the inner surface; a glass layer located between the inner surface and the outer surface; and a first layer of light transmitting ink or pigment located between the inner surface of the cover structure and the glass layer. The deadfront article also includes a light guide layer having: an inner surface; and an outer surface facing toward the inner surface of the cover structure. A light extraction layer located on at least one of the inner surface and the outer surface of the light guide layer.

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.
