摘要：
This application describes a back- lit transmissive display including a transmissive display ( 620 ) and a variable index light extraction layer ( 640 ) optically coupled to a lightguide ( 630 ). The variable index light extraction layer has first regions ( 140 ) of nanovoided polymeric material and second regions ( 130 ) of the nanovoided polymeric material and an additional material. The first and second regions are disposed such that for light being transported at a supercritical angle in the lightguide, the variable index light extraction layer selectively extracts the light in a predetermined way based on the geometric arrangement of the first and second regions. The transmissive display may be a transmissive display panel or a polymeric film such as a graphic.
摘要（中）：
该应用描述了背光透射显示器，其包括光学耦合到光导（630）的透射显示器（620）和可变折射率光提取层（640）。 可变折射率光提取层具有纳米型聚合物材料的第一区域（140）和纳米复合聚合物材料的第二区域（130）和附加材料。 第一和第二区域被布置成使得对于在光导中以超临界角传输的光，可变索引光提取层基于第一和第二区域的几何布置以预定方式选择性地提取光。 透射显示器可以是透射显示面板或诸如图形的聚合物膜。
