Self-healing electronic materials can substantially enhance the life-time of a device as they can self-repair mechanical damages, thereby recovering their initial electronic performance similar to human skin. Here, shape-deformable and self-healing EL displays (SSELD) are presented. Light emitting materials are fabricated by adding a certain amount of a plasticizer, Triton X-100, to elastomeric poly(urethane) containing light-emitting Cu-doped ZnS microparticles to obtain a viscoelastic composite that undergoes facile shape-deformation and recovery. A SSELD exhibits frequency-dependent field-induced light emission under alternating current (AC). More importantly, a SSELD self-recovers its EL within few minutes of electrical failure. Further, the AC EL device endures more than 100 cycles of failure-recovery operations. By combining with a shape-deformable ionic liquid, a novel fiber display which exhibits excellent shape-deformable and self-healing EL performance, is demonstrated.
