Endowing three-dimensional (3D) displays with flexibility drives innovation in the next-generation wearable and smart electronic technology. Printing circularly polarized luminescence (CPL) materials on stretchable panels gives the chance to build desired flexible stereoscopic displays: CPL provides unusual optical rotation characteristics to achieve the considerable contrast ratio and wide viewing angle. However, the lack of printable, intense circularly polarized optical materials suitable for flexible processing hinders the implementation of flexible 3D devices. Here, we report a controllable and macroscopic production of printable CPL-active photonic paints using a designed confining helical co-assembly strategy, achieving a maximum luminescence dissymmetry factor () value of 1.6. We print customized graphics and meter-long luminous coatings with these paints on a range of substates such as polypropylene, cotton fabric, and polyester fabric. We then demonstrate a flexible textile 3D display panel with two printed sets of pixel arrays based on the orthogonal CPL emission, which lays an efficient framework for future intelligent displays and clothing.
赋予三维(3D)显示器灵活性推动了下一代可穿戴和智能电子技术的创新。在可拉伸面板上打印圆偏振发光(CPL)材料为构建所需的柔性立体显示器提供了机会:CPL提供了不同寻常的旋光特性,以实现可观的对比度和宽视角。然而,缺乏适用于柔性加工的可打印、高强度圆偏振光学材料阻碍了柔性3D设备的实现。在此,我们报告了一种使用设计的受限螺旋共组装策略可控且宏观地生产可打印CPL活性光子涂料的方法,实现了最大发光不对称因子()值为1.6。我们用这些涂料在一系列基材上打印定制图形和米长的发光涂层,如聚丙烯、棉织物和聚酯织物。然后,我们展示了一个基于正交CPL发射的具有两组打印像素阵列的柔性纺织3D显示面板,这为未来的智能显示器和服装奠定了高效的框架。
