Encapsulation sheet, flat panel display device using the same, and method of manufacturing the flat panel display device
View Patent ↗An encapsulation sheet, a flat panel display device, and a method of manufacturing a flat panel display device are disclosed. The method includes: forming a getter on a first sheet; forming a sealant having a space corresponding to the shape of the getter on a second sheet; forming an encapsulation sheet by folding the first sheet and the second sheet to enter the getter into the space; and attaching the encapsulation sheet on a substrate on which a display unit is formed. When the flat panel display device is manufactured using the above method, the folded sealant and the getter are simultaneously mounted on the substrate, and thus, a complicated conventional process of mounting the getter in a vacuum state is unnecessary.
1. A flat panel display device comprising:
a substrate;
a display unit formed on the substrate;
an encapsulation sheet that covers the display unit; and
a sealing substrate formed on the encapsulation sheet,
wherein the encapsulation sheet comprises:
a getter that surrounds the display unit to absorb moisture; and
a sealant that fills a space between the substrate and the encapsulation sheet together with the getter for absorbing moisture.
2. The flat panel display device of claim 1 , wherein the getter has a closed loop shape that surrounds the display unit.
3. The flat panel display device of claim 1 , wherein the sealant comprises:
a first sealant portion formed in the center region of the second sheet that corresponds to the display unit; and
a second sealant portion formed in an edge region of the second sheet that corresponds to an edge region of the display unit,
wherein the space is located between the first and second sealant portions.
4. An encapsulation sheet comprising:
a first sheet on which a getter is formed; and
a second sheet on which a sealant having a space corresponding to the shape of the getter is formed,
wherein the first sheet and the second sheet are folded so that the getter enters into the space.
5. The encapsulation sheet of claim 4 , wherein the getter has a closed loop shape.
6. A flat panel display device comprising the encapsulation sheet of claim 5 .
7. The encapsulation sheet of claim 4 , wherein the sealant comprises:
a first sealant portion formed in the center region of the second sheet; and
a second sealant portion formed in an edge region of the second sheet, wherein the space is located between the first and second sealant portions.
8. A flat panel display device comprising the encapsulation sheet of claim 7 .
9. A flat panel display device comprising the encapsulation sheet of claim 4 .
10. A method of manufacturing a flat panel display device, the method comprising:
providing a substrate;
forming a display unit on the substrate;
forming a getter on a first sheet;
forming a sealant having a space corresponding to the shape of the getter on a second sheet;
forming an encapsulation sheet by folding the first sheet and the second sheet so the getter enters into the space; and
attaching the encapsulation sheet to the substrate.
11. The method of claim 10 , wherein the attaching of the encapsulation sheet on the substrate comprises:
removing one of the first sheet and the second sheet of the encapsulation sheet;
attaching the surface of the encapsulation sheet, from which one of the first sheet and the second sheet is removed, to the substrate; and
removing the remaining one of the first sheet and the second sheet of the encapsulation sheet.
12. The method of claim 10 , further comprising forming a sealing substrate on the encapsulation sheet.
13. A flat panel display device manufactured by the method of claim 12 .
14. The method of claim 10 , wherein the getter has a closed loop shape that surrounds the display unit.
15. A flat panel display device manufactured by the method of claim 14 .
16. The method of claim 10 , wherein the sealant comprises:
a first sealant portion formed in the center region of the second sheet that corresponds to the display unit; and
a second sealant portion formed in an edge region of the second sheet that corresponds to an edge region of the display unit,
wherein the space is located between the first and second sealant portions.
17. A flat panel display device manufactured by the method of claim 16 .
18. A flat panel display device manufactured by the method of claim 10 .
19. A flat panel display device manufactured by the method of claim 11 .
