Organic light emitting display device
View Patent ↗An organic light emitting display device includes a substrate; an organic light emitting unit formed on the substrate; and a sealing unit which seals the organic light emitting unit, wherein the sealing unit is formed by alternately stacking at least one first thin film and at least one second thin film, the first thin film being formed to surround a portion of the second thin film.
1. An organic light emitting display device comprising:
a substrate;
an organic light emitting unit disposed on the substrate;
a sealing unit disposed over the organic light emitting unit and at least a portion of the substrate, thereby sealing the organic light emitting unit therein, wherein the sealing unit comprises at least one first thin film and at least one second thin film alternately stacked, the first thin film encapsulating the second thin film; and
a getter layer disposed on the at least one first thin film, wherein the getter layer is substantially not disposed over the organic light emitting unit.
2. The device of claim 1 , wherein the at least one first thin film is wider than the at least one second thin film.
3. The device of claim 1 , comprising a plurality of stacked first thin films, wherein each of the stacked first thin films has substantially the same width.
4. The device of claim 3 , comprising a plurality of stacked second thin films, wherein each of the stacked second thin films has substantially the same width.
5. The device of claim 1 , wherein the at least one first thin film comprises an inorganic material.
6. The device of claim 1 , wherein the at least one second thin film comprises an organic material.
7. The device of claim 1 , wherein the getter layer comprises a reactive metal.
8. The device of claim 1 , wherein the getter layer comprises metal oxide.
9. The device of claim 1 , wherein the at least one first thin film is wider than the at least one second thin film.
10. The device of claim 1 , comprising a plurality of stacked first thin films, wherein each of the stacked first thin films has substantially the same width.
11. The device of claim 10 , comprising a plurality of stacked second thin films, wherein each of the stacked second thin films has substantially the same width.
12. The device of claim 1 , wherein the at least one first thin film comprises an inorganic material.
13. The device of claim 1 , wherein the at least one second thin films comprises an organic material.
