The development of wearable devices has increased the need for organic light-emitting diodes (OLEDs) that are soft, stretchable, and can integrate seamlessly with the human body. Traditional intrinsically stretchable OLEDs (is-OLED) often suffer from reduced performance due to orthogonal solvent problem and lamination fabrication process, which can cause defects and delamination. To overcome these challenges, we developed a sequentially coated is-OLED and confirmed the maintenance of the designed morphologies of each layer and a highly stretchable metallic is-cathode. Our is-OLEDs achieved a maximum total luminance of 3151 cd m^–2 and a total current efficiency of 5.4 cd A^–1. It also demonstrated superior durability, with the ability to stretch up to 70% and maintain 80% luminance after 300 cycles at 40% strain. This advancement suggests a promising future for durable and efficient soft electronic devices.

可穿戴设备的发展增加了对柔软、可拉伸且能够与人体无缝融合的有机发光二极管（OLED）的需求。传统的本质可拉伸 OLED ( is- OLED) 通常会因正交溶剂问题和层压制造工艺而导致性能下降，从而导致缺陷和分层。为了克服这些挑战，我们开发了一种顺序涂覆的is- OLED，并确认了每层的设计形态和高度可拉伸的金属is-阴极的保持。我们的is- OLED 实现了 3151 cd m ^–2的最大总亮度和 5.4 cd A ^–1的总电流效率。它还表现出卓越的耐用性，在 40% 应变下进行 300 次循环后，能够拉伸高达 70% 并保持 80% 的亮度。这一进步预示着耐用且高效的软电子设备的光明前景。
