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

The two pieces each function as individual EL devices. Cutting a large EL device into smaller pieces results in smaller individual EL devices. The two pieces 1202, 1204 are coupled by using the self-healing ability of each of the pieces 1202, 1204. The two pieces 1202, 1204 are held against each other. The two pieces may be covered by a solvent to improve (i.e. facilitate) healing. The two pieces selfheal and become coupled together to form the “T” shape. Each layer of each EL device 1202, 1204 self-heals and couples to the corresponding adjacent layers between the two devices. For example the first electrode of the first EL device heals and couples to the first electrode of the second EL device at the locations where the two EL devices are brought into contact with each other. Similar healing occurs for the electroluminescence device and the second electrode.
