Electrochromic (EC) reflective displays offer great advantages in delivering information and providing visual data, but are limited in dark environments. Reflective/emissive dual-modal displays capable of electrochemically-induced color and fluorescence change simultaneously are highly desirable, especially possessing rapid response speed as well as long-term durability. Herein, an electroactive fluorescent ionic liquid based on triphenylamine and imidazole (EFIL-TPA) has been synthesized for reflective/emissive dual-modal display. The resultant device exhibits outstanding electrochromic/electrofluorochromic (EC/EFC) performance with low driving voltage (below 1.0 V), fast switching speed (0.57–1.8 s), and remarkable cycling durability (91% retention for 10 000 cycles). A piezoelectric nanogenerator (PENG) driven EC/EFC integrated system is fabricated to harvest energy from human motion and visually drive the color/fluorescence change for human motion indication in both bright and dark environments. This innovative EC/EFC dual-modal display device based on EFIL-TPA supports a huge space for the development of self-powered human motion visualized indication in all-light conditions.

压电驱动电致变色/电荧光致变色双模态显示装置

电致变色 (EC) 反射式显示器在传递信息和提供视觉数据方面具有巨大优势，但在黑暗环境中受到限制。能够同时电化学诱导颜色和荧光变化的反射/发射双模式显示器是非常理想的，特别是具有快速响应速度和长期耐用性。在此，合成了一种基于三苯胺和咪唑的电活性荧光离子液体（EFIL-TPA），用于反射/发射双模态显示。由此产生的器件表现出出色的电致变色/电荧光变色 (EC/EFC) 性能，具有低驱动电压（低于 1.0 V）、快速开关速度（0.57–1.8 s）和卓越的循环耐久性（10 000 次循环保持率为 91%）。压电纳米发电机 (PENG) 驱动的 EC/EFC 集成系统旨在从人体运动中收集能量，并在明亮和黑暗的环境中视觉驱动颜色/荧光变化以指示人体运动。这种基于EFIL-TPA的创新EC/EFC双模态显示器件为全光条件下自供电人体运动可视化指示的发展提供了巨大的空间。
