More Information
Summary:A light control film includes: first and second opposing major surfaces that are substantially flat, substantially parallel, the first and second major surfaces being spaced apart in a thickness direction of the light control film by an interval of less than about 500 microns; and a plurality of substantially parallel, optically transparent polymeric columns disposed in and substantially surrounded by the light absorbing polymeric material. Each polymer column has a first column end located at the first major surface and an opposite second column end located at the second major surface, and has an aspect ratio greater than about 3 such that the first column ends of at least one pair of adjacent polymer columns include substantially parallel, substantially straight sides facing each other and substantially coextending. 一种光控膜包括：大致平坦、大致平行的相反的第一主表面和第二主表面，该第一主表面和第二主表面沿该光控膜的厚度方向隔开小于约500微米的间隔；和大致平行、光学透明的多个聚合物柱，该多个聚合物柱设置在光吸收聚合物材料中并且大致由该光吸收聚合物材料包围。每个聚合物柱具有位于该第一主表面处的第一柱端和位于该第二主表面处的相反的第二柱端，并且具有大于约3的长宽比，使得至少一对相邻聚合物柱的该第一柱
