    • A backlight system includes an extended area light guide (120) and crossed first (128) and second (130) prismatic recycling films. The light guide provides a first light distribution that has a maximum luminance at a first polar angle, e.g., from 70 to 90 degrees, relative to the optical axis (116) of the system. The recycling films provide a second light distribution. No diffuser film is provided between the light guide and the recycling film disposed nearest the light guide. Instead, light is specularly transmitted from the output surf ace (120a) of the light guide to the input surf ace (128a) of the recycling film nearest the light guide. The recycling films comprise prisms having refractive indices tailored to provide the second light distribution with a maximum luminance at a polar angle of 10 degrees or less. The prisms preferably have a refractive index from 1.63 to 1.76. Related methods and articles are also disclosed.
    • 背光系统包括延伸区域光导(120)和交叉的第一(128)和第二(130)棱镜回收膜。 光导提供第一光分布,该第一光分布相对于系统的光轴(116)具有在第一极角(例如,70至90度)处的最大亮度。 回收膜提供第二光分布。 在光导和最靠近导光体设置的回收膜之间不设置漫射膜。 相反,光从光导的输出冲浪(120a)镜像地传输到最靠近光导的再循环膜的输入冲浪(128a)。 回收膜包括具有定制的折射率的棱镜,以提供具有10度或更小的极角的最大亮度的第二光分布。 棱镜优选具有1.63至1.76的折射率。 还公开了相关的方法和文章。
