摘　　要：采用封装胶/密封脂/封口膜的三重封装策略,柔性超高分辨量子点发光二极管(FUQLED)达到IPX7级防水标准。该FUQLED具备9 072 ppi的分辨率和10.8%的外量子效率(EQE),以及卓越的防水性能。在水下的工作寿命(LT50)超过60 min,即使在36 h的水下浸泡后,亮度依然保持在5 000 cd/m^(2)以上。这一防水架构为高信息密度的可穿戴医疗监测系统提供了极具前景的解决方案。A triple-encapsulation strategy was using,employing packaging glue,sealing paste,and sealing film to develop flexible ultra-high-resolution quantum dot light-emitting diodes(FUQLEDs)that could achieve an IPX7 waterproof rating.These FUQLEDs featured a resolution of 9072 ppi and an external quantum efficiency(EQE)of 10.8%,demonstrating exceptional waterproof performance.The operational lifetime(LT50)underwater exceeded 60 minutes,and even after 36 hours of submersion,the brightness remained above 5000 cd/m^(2).This waterproof architecture could offer a promising solution for wearable medical monitoring systems with high information density.
