摘要:
An organic light emitting diode comprising a first electrode layer, a second electrode layer, a stack of functional layers, including an organic light-emitting layer, sandwiched between said first electrode layer and said second electrode layer, and an passivation layer arranged adjacent to said first electrode layer is disclosed. The passivation layer reacts with the first electrode layer to form an oxide at a reaction temperature that is induced by an evolving short circuit between the first electrode layer and the second electrode layer. The passivation layer is unreactive at temperatures lower than the reaction temperature.

摘要:
An EL structure is described, with a single ultraviolet or blue light emitting layer that is connected to a back electrode. The top surface comprises three separate segments for the primary colors red, green and blue. Another single phosphorescent blend or a two-component phosphorescent blend is deposited on at least two of the three segments. Each of the three segments can be individually driven by a corresponding top electrode. Thus, a single chip solution is provided for a LED with tunable visible light.
