We report an electrical-field switched color device using a polymer-stabilized blue-phase (PSBP) liquid crystal in which the Bragg-reflected color of the blue phase (BP) can be switched to reflect a second color. The phase-separated three-dimensional polymer network transcribes the cubic structure of a BP liquid crystal and restrains the deformation of cubic lattice by the external electric field. The new wide-range electric-field switched colors with PSBP may be an important step toward ecofriendly color reflective displays.
我们报告了一种电场切换彩色器件，使用聚合物稳定的蓝相（PSBP）液晶，其中蓝相（BP）的布拉格反射颜色可以切换到反射第二种颜色。相分离的三维聚合物网络转录 BP 液晶的立方结构，并通过外部电场抑制立方晶格的变形。具有 PSBP 的新宽范围电场切换颜色可能是朝着环保型彩色反射显示器迈出的重要一步。
