Abstract
An organic light emitting device includes a substrate. An organic light emitting diode is disposed on the substrate. A thin film encapsulation layer is disposed over the organic light emitting diode. The thin film encapsulation layer includes at least one organic layer. An organic passivation layer is disposed directly on the thin film encapsulation layer. The organic passivation layer has a smaller Young's modulus than the organic layer of the thin film encapsulation layer.
Claims15
An organic light emitting device comprising:
- a substrate;
- an organic light emitting diode disposed on the substrate;
- a thin film encapsulation layer disposed over the organic light emitting diode, the thin film encapsulation layer including at least one organic layer and a least one inorganic layer;
- and
- an organic passivation layer disposed directly on the thin film encapsulation layer,
- wherein the organic passivation layer has a smaller Young's modulus than the at least one organic layer of the thin film encapsulation layer,
- wherein the inorganic layer is an uppermost layer of the thin film encapsulation layer, and
- wherein the organic passivation layer directly contacts the inorganic layer.
An organic light emitting device, comprising:
- a flexible substrate;
- an organic light emitting diode disposed on the flexible substrate;
- a thin film encapsulation layer disposed on the flexible substrate so as to encapsulate the organic light emitting diode, the thin film encapsulating layer including a first inorganic layer disposed on the organic light emitting diode, an organic layer disposed on the first inorganic layer, and a second inorganic layer disposed on the organic layer;
- and
- an organic passivation layer disposed over the thin film encapsulation layer,
- wherein the organic layer of the thin film encapsulation layer is more elastic than the organic passivation layer, and
- wherein the organic passivation layer directly contacts the second inorganic layer.
