This study demonstrates self-healable and shape-transformable EL displays (SSELDs). Light-emitting materials are fabricated by adding a amount of a plasticizer, Triton X-100, to elastomeric poly(urethane) containing light-emitting Cu-doped ZnS microparticles to obtain a viscoelastic composite. A capacitive SSELD exhibits frequency-dependent field-induced light emission under alternating current. Color mixing and tuning of EL is achieved by mixing two or more Cu-doped ZnS microparticles. Most importantly, an 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 that exhibits excellent shape-deformable and self-healing EL performance is demonstrated.
