Abstract
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.
Claims15
An organic light emitting diode, comprising:
- a first electrode layer;
- a second electrode layer;
- an organic light-emitting layer disposed between the first electrode layer and the second electrode layer;
- and
- a passivation layer arranged adjacent to the first electrode layer,
- wherein the passivation layer is reactive with the first electrode layer to form a passive material at a reaction temperature induced by an evolving short circuit,
- wherein
- the first electrode is comprised of a low work-function material, and
- the passivation layer comprises at least one clathrate material.
