我们展示了窄带宽模板化胆甾型液晶薄膜。随着再填充材料双折射的降低，这些薄膜的反射带宽可以显着变窄。从具有各向异性折射率的液晶到具有各向同性折射率的甲苯的不同材料已被重新填充到具有螺旋结构的聚合物支架中，该螺旋结构源自胆甾型液晶的周期性排列。还研究了温度对薄膜线宽的影响。基于这些填充有小型双折射液晶的柔性反射膜，实验演示了全色反射式显示器。这些柔性薄膜的应用包括柔性反射显示器、数码照片中的彩色像素、印刷和各种物体的彩色覆层。
We demonstrate narrow bandwidth templated cholesteric liquid crystal films. The reflection bandwidth of these films can be dramatically narrowed with the reduced birefringence of refilled materials. Different materials from liquid crystals with anisotropic refractive index to toluene with isotropic refractive index have been refilled to polymer scaffolds with helical structures which originate from the periodic arrangement of cholesteric liquid crystals. The temperature effect on the linewidth of the films is also studied. A full-color reflective display is experimentally demonstrated based on these flexible reflective films that are refilled with small birefringence liquid crystals. The applications of these flexible films include flexible reflective display, color pixels in digital photographs, printing and colored cladding of variety of objects.
