Organic light-emitting display apparatus having a flexible substrate
An organic light-emitting display apparatus includes a flexible substrate. The organic light-emitting display apparatus includes a first plastic layer. A first barrier layer is formed on the first plastic layer. A second plastic layer is formed on the first barrier layer. An organic light-emitting device layer is formed on the second plastic layer. A thin film encapsulating layer encapsulates the organic light-emitting device layer. The first barrier layer is patterned to correspond to an area where the organic light-emitting device layer is formed.
1. An organic light-emitting display apparatus comprising:
a first flexible plastic layer;
a first barrier layer formed on the first flexible plastic layer, the first barrier layer being substantially impervious to water and oxygen;
a second flexible plastic layer formed on the first barrier layer;
an organic light-emitting device layer formed on the second flexible plastic layer; and
a thin film encapsulating layer encapsulating the organic light-emitting device layer, wherein the first barrier layer is patterned to correspond to an area where the organic light-emitting device layer is formed and the first flexible plastic layer is in contact with the second flexible plastic layer in an area that surrounds the first barrier layer.
2. The organic light-emitting display apparatus of claim 1 , wherein the first flexible plastic layer is in contact with the second flexible plastic layer in an outer part of an area where the organic light-emitting device layer is formed.
3. The organic light-emitting display apparatus of claim 1 , further comprising a second barrier layer, substantially impervious to water and oxygen, between the second flexible plastic layer and the organic light-emitting device layer.
4. The organic light-emitting display apparatus of claim 3 , wherein the second barrier layer comprises at least one layer including an inorganic material.
5. The organic light-emitting display apparatus of claim 3 , wherein the second barrier layer is patterned to be located in an area where the organic light-emitting device layer is formed.
6. The organic light-emitting display apparatus of claim 5 , wherein the second barrier layer is in contact with the thin film encapsulating layer in an outer part of an area where the organic light-emitting device layer is formed.
7. The organic light-emitting display apparatus of claim 3 , wherein at least one pair of layers, each layer including a third flexible plastic layer and a third barrier layer, substantially impervious to water and oxygen, is formed between the second barrier layer and the organic light-emitting device layer.
8. The organic light-emitting display apparatus of claim 7 , wherein the second barrier layer is patterned to be located in an area where the organic light-emitting device layer is formed.
9. The organic light-emitting display apparatus of claim 1 , wherein the first plastic flexible layer and the second plastic flexible layer comprise polyiminde, polyethylene naphthalate, polyethyleneterephthalate, polyarylate, polycarbonate, polyethersulfone, or polyetherimide.
10. The organic light-emitting display apparatus of claim 1 , wherein a thickness of the second plastic flexible layer is larger than that of the first plastic flexible layer.
11. The organic light-emitting display apparatus of claim 1 , wherein the second plastic flexible layer has a lower viscosity than the first plastic flexible layer.
12. The organic light-emitting display apparatus of claim 1 , wherein the first barrier layer comprises at least one layer including an inorganic material.
13. An electronic device including the organic light-emitting display apparatus of claim 1 .
