Claim of US Patent No. 10,251,238

1. An electroluminescent device comprising:a first contact structure, the first contact structure comprising an ionic conductor layer and an electrode in contact with the ionic conductor layer;
a second contact structure; and
an emission layer between the first contact structure and the second contact structure; wherein:
the emission layer is configured to emit light when an alternating voltage is applied between the first contact structure and the second contact structure;
the emission layer comprises an elastomer and one or more electroluminescent elements embedded in the elastomer;
the electrode of the first contact structure and the ionic conductor layer form an interface having a capacitive value higher than a capacitive value of the emission layer; and
the emission layer is in contact with ionic conductor layer.
