    • Optical films are described comprising a color shifting film comprising a matte surface layer; and light control microstructured layer disposed proximate the color shifting film. The optical film may comprise a matte layer disposed on a major surface of the color shifting film and the light control microstructured layer disposed on the color shifting film at an interface that is free of adhesive. Alternatively, the optical film may comprise a film stack comprising a light control film having a light control microstructured layer, a color shifting film, and an adhesive layer between the light control film and color shifting film. In some embodiments, the matte layer comprises matte particles. In other embodiments, the matte layer comprises a plurality of microstructures and no greater than 50% of the microstructures comprise embedded matte particles. In some embodiments, the microstructures are substantially free of embedded matte particles.
    • 描述了包括含有无光泽表面层的色移膜的光学膜; 以及设置在色移膜附近的光控微结构层。 光学膜可以包括设置在色移膜的主表面上的消光层和在不具有粘合剂的界面处设置在色移膜上的光控微结构层。 或者,光学膜可以包括膜堆叠,其包括具有光控微结构层,变色膜和在光控膜和变色膜之间的粘合剂层的光控膜。 在一些实施例中,无光泽层包括无光泽颗粒。 在其它实施例中,无光泽层包括多个微结构,并且不超过50%的微结构包含嵌入的无光泽颗粒。 在一些实施例中,微结构基本上没有嵌入的磨砂颗粒。

    • Provided is a light control film and displays incorporating same. In particular, provided are light control films comprising a light input surface and a light output surface opposite the light input surface. The light control films further comprise alternating transmissive and absorptive regions disposed between the light input surface and the light output surface. Each transmissive region has an index of refraction N1, and each absorptive region having an index of refraction N2, where N2-N1 is not less than - 0.005.The average pitch of successive absorptive regions of 0.070 mm or less. Light incident to the light input surface exits the light output surface with a maximum relative brightness ratio (RBR) in a direction perpendicular to the light output surface of 65 or greater, and exits the light output surface with an effective polar viewing angle (EPVA) of 45? or less.
    • 提供了一种光控薄膜和包含其的显示器。 特别地,提供了包括光输入表面和与光输入表面相对的光输出表面的光控制膜。 光控制膜还包括布置在光输入表面和光输出表面之间的交替透射和吸收区域。 每个透射区域具有折射率N1,并且每个吸收区域具有折射率N2,其中N2-N1不小于0.005。连续吸收区域的平均间距为0.070mm或更小。 入射到光输入表面的光在与光输出表面垂直的方向上具有最大相对亮度比(RBR)为65或更大的光输出表面,并以有效的极视角(EPVA)离开光输出表面, 45? 或更少。
