Abstract: High Resolution Image Download MS PowerPoint Slide We report a fully addressable smart textile display using quantum dot light-emitting diodes (QD-LEDs) featuring a highly durable electrode. The key innovation lies in the development of an ultrathin oxide/metal hybrid structure for the durable electrode, which achieves mechanical bending durability surpassing the indium tin oxide (ITO) electrode. The optimized electrode, composed of MoO 3 and Au, exhibits a transmittance of T 550 = 81%, while maintaining a sheet resistance of R s = 17.92, achieving a Figure of Merit (FoM) of 0.0077. The bending tests further demonstrate that the QD-LEDs with this electrode retain their luminance up to 6325 cd m –2 after undergoing 500 bending cycles at a bending radius of 5 mm. Furthermore, this study introduces not only a highly mechanically robust device, but also an integration method for textile systems by employing an innovative lateral driving display system architecture enabling the precise addressing of individual QD-LEDs in a textile display.
