    • 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.
    • 背光源可以包括光导和光输入。 光导可以具有光反射表面和光发射表面。 光输入可以包括具有延伸到窄端的窄端和相对侧表面的发散楔。 可以在光输入中形成光源阱,并且光源可以设置在光源井内。 密封剂可以围绕光源设置在光源井内。 镜面反射膜或层可以设置成与相对的侧表面相邻但不紧密接触,并且可以反射入射在多层聚合物镜膜上的多于80%的可见光。
