Abstract
A backlight may include a light guide and a light input. The light guide may have a light reflection surface and a light emission surface. The light input may include a diverging wedge having a narrow end and opposing side surfaces extending to the narrow end. A light source well may be formed in the light input, and a light source may be disposed within the light source well. An encapsulant may be disposed about the light source, within the light source well. A specularly reflective film or layer may be disposed adjacent to but not in intimate contact with the opposing side surfaces and may reflect more than 80% of visible light incident on the multilayer polymeric mirror film.
