摘要

An electroluminescent device including an electrode, the electrode being ionically conductive; an electroluminescence layer positioned adjacent or in contact with the electrode, the electroluminescence layer being electrically coupled to the electrode; the electroluminescence layer receiving electrical energy from the electrode and illuminating in response to received electrical energy, and wherein the electrode and the electroluminescence layer are repairable such that the function of the electrode and the electroluminescence layer is restored after a deformation.

說明書

FIG. 1 shows an exemplary configuration of an electroluminescent device 100 (i.e. EL device). The EL device 100 is adaptable to mechanical loading such that it maintains functionality in response to various mechanical loads. The EL device 100 is also substantially flexible along at least one axis. Preferably the EL device 100 is flexible in response to one or more of bending loads, torsion loads, tensile loads and compression loads, the electroluminescent device is flexible such that function of the electroluminescence device is maintained in response to any one or more of the loads. More preferably EL device 100 is flexible in response to all of the loads such that function of the electroluminescence device is maintained in response to all of the loads.

The EL device 100 comprises a multi-layer structure. The EL device 100 may comprise a laminate multi-layer structure where the layers are attached to form a unitary structure. FIG. 1 shows an example configuration of the EL device multi-layer structure 102.

Referring to FIG. 1, the EL device 100 comprises a first electrode 110, a second electrode 120 and an electroluminescence layer 130 forming the multi-layer structure 102. The first electrode 110 and the second electrode 120 may be substantially identical to each other. The first electrode 110 and the second electrode 120 are ionically conductive. The electroluminescence layer 130 is arranged in electrical communication with the first electrode 110 and the second electrode 120.
