Abstract

A flat panel display including a light emitting device having a sealed image display area, an encapsulating member, and an auxiliary encapsulating member. The encapsulating member is curved to have a space in which the light emitting device is sealed. The auxiliary encapsulating member is arranged on at least a bent portion of the encapsulating member.

Claims (69)

1. A flat panel display, comprising:

a light emitting device having a sealed image display area;

an encapsulating member curved to form an enclosed space, where the light emitting device is arranged in the enclosed space; and

an auxiliary encapsulating member arranged on at least a bent portion of the encapsulating member but not on a portion of the encapsulating member through which an image is displayed.

2. The flat panel display of claim 1 , wherein the encapsulating member is a protection film comprising a single sheet.

3. The flat panel display of claim 2 , wherein the auxiliary encapsulating member is arranged on an outer surface of the bent portion of the protection film.

4. The flat panel display of claim 2 , wherein the auxiliary encapsulating member is arranged on an inner surface of the bent portion of the protection film.

5. The flat panel display of claim 2 , wherein the auxiliary encapsulating member is separately formed and bonded with the protection film.

6. The flat panel display of claim 2 , wherein the auxiliary encapsulating member is formed on the protection film by deposition.

7. The flat panel display of claim 1 , wherein the encapsulating member includes a pair of protection films that face each other and are bonded with each other.

8. The flat panel display of claim 7 , wherein the auxiliary encapsulating member couples the protection films with each other.

9. The flat panel display of claim 1 , wherein the encapsulating member includes a protection film and an opposing film that faces the protection film and is bonded with the protection film.

10. The flat panel display of claim 9 , wherein the auxiliary encapsulating member couples the protection film and the opposing film with each other.

11. The flat panel display of claim 9 , wherein the opposing film comprises the auxiliary encapsulating member.

12. The flat panel display of claim 9 , wherein the opposing film is transparent.

13. The flat panel display of claim 9 , wherein the opposing film is opaque.

14. The flat panel display of claim 2 , wherein the protection film is flexible.

15. The flat panel display of claim 9 , wherein the opposing film is flexible.

16. The flat panel display of claim 1 , wherein the encapsulating member comprises three edges where sealing occurs.

17. The flat panel display of claim 1 , further comprising:

an adhering unit positioned between the encapsulating member and the light emitting device.

18. The flat panel display of claim 1 , further comprising:

a moisture absorbing unit positioned between the encapsulating member and the light emitting device.

19. The flat panel display of claim 2 , wherein the protection film comprises a plastic film comprising an inorganic layer.

20. The flat panel display of claim 19 , wherein the inorganic layer is formed of at least one material selected from the group consisting of silicon, metal oxide, metal nitride, metal carbide, metal oxynitride, a ceramic derivative of silicon, a ceramic derivative of metal, diamond-like carbon, and a compound thereof.

21. The flat panel display of claim 19 , wherein the plastic film further comprises a polymer layer, the polymer layer being formed of at least one material selected from the group consisting of an organic polymer, an inorganic polymer, an organometallic polymer, and a hybrid organic/inorganic polymer.

22. The flat panel display of claim 1 , wherein the auxiliary encapsulating member comprises a metal.

23. The flat panel display of claim 1 , wherein the sealing element seals the image display area by being coupled with a substrate of the light emitting device; and wherein the substrate is formed of one of glass, plastic, and metal.

24. The flat panel display of claim 1 , wherein the sealing element seals the image display area by being coupled with a substrate of the light emitting device; and wherein the sealing element is a plate.

25. The flat panel display of claim 1 , wherein the sealing element seals the image display area by being coupled with a substrate of the light emitting device; and wherein the sealing element is a film.

26. A method of manufacturing a flat panel display, comprising:

forming a light emitting device by forming an image display area on a substrate and sealing the image display area;

setting the light emitting device on an encapsulating member;

arranging an auxiliary encapsulating member on the encapsulating member;

bending the encapsulating member so that the light emitting device is within a space made by the bent encapsulating member; and

sealing edges of the encapsulating member,

wherein the auxiliary encapsulating member is located at a bent portion of the encapsulating member but not on a portion of the encapsulating member through which an image is displayed.

27. The method of claim 26 , wherein sealing the edges of the encapsulating member comprises:

coating the edges of the encapsulating member with an adhesive;

sealing the edges of the encapsulating member with at least a portion of the sealed edges open;

exhausting air from the space made by the bent encapsulating member; and

sealing the open portion.

28. The method of claim 26 , wherein sealing the edges of the encapsulating member comprises:

coating the edges of the encapsulating member with an adhesive;

sealing the edges of the encapsulating member with at least a portion of the sealed edges open;

inserting an inert gas into the space made by the bent encapsulating member; and

sealing the open portion.

29. The method of claim 26 , wherein sealing the edges of the encapsulating member comprises:

coating the edges of the encapsulating member with an adhesive;

forming a vacuum in the space made by the bent encapsulating member; and

sealing the edges of the encapsulating member coated with the adhesive.

30. The method of claim 26 , wherein sealing the edges of the encapsulating member comprises:

coating the edges of the encapsulating member with an adhesive;

forming an inert gas ambient in the space made by the bent encapsulating member; and

sealing the edges of the encapsulating member coated with the adhesive.

31. The method of claim 26 , further comprising:

forming an adhering unit on a surface of the encapsulating member to set the light emitting device thereon.

32. The method of claim 26 , further comprising:

forming a moisture absorbing unit on a surface of the encapsulating member to set the light emitting device thereon.

33. The method of claim 26 , wherein the encapsulating member is a protection film comprising a single sheet.

34. The method of claim 26 , wherein the encapsulating member includes a pair of protection films that face each other and are bonded with each other.

35. The method of claim 34 , wherein the auxiliary encapsulating member couples the protection films with each other.

36. The method of claim 26 , wherein the encapsulating member includes a protection film and an opposing film that faces the protection film and is bonded with the protection film.

37. The method of claim 36 , wherein the auxiliary encapsulating member couples the protection film and the opposing film with each other.

38. The method of claim 36 , wherein the opposing film comprises the auxiliary encapsulating member.

39. The method of claim 33 , wherein the protection film comprises a plastic film comprising an inorganic layer.

40. The method of claim 39 , wherein the inorganic layer is formed of at least one material selected from the group consisting of silicon, metal oxide, metal nitride, metal carbide, metal oxynitride, a ceramic derivative of silicon, a ceramic derivative of metal, diamond-like carbon, and a compound thereof.
