Abstract

An organic light-emitting display includes a first substrate which includes a pixel region, and an encapsulation region which surrounds the pixel region, an organic light-emitting device which is located in the pixel region, a sealant which is located in the encapsulation region, and a dummy metal which is interposed between the first substrate and the sealant, where the encapsulation region includes a first encapsulation region and a second encapsulation region which is adjacent to the first encapsulation region, and the dummy metal is located in the first encapsulation region.

Claims (61)

1. An organic light-emitting display comprising:

a first substrate which comprises:

a pixel region; and

an encapsulation region which surrounds the pixel region;

an organic light-emitting device which is located in the pixel region;

a sealant which is located in the encapsulation region;

a dummy metal which is interposed between the first substrate and the sealant;

an antenna which is located on the first substrate; and

an insulating layer which is interposed between the first substrate and the sealant, wherein an opening is defined by the insulating layer, and at least a portion of the antenna overlaps the opening,

wherein

the encapsulation region comprises a first encapsulation region, and a second encapsulation region which is contiguous to the first encapsulation region and abutting a periphery of the first encapsulation region,

the dummy metal is located only in the first encapsulation region between the second encapsulation region and the pixel region

the organic light-emitting device and the sealant are located on a first surface of the first substrate,

the antenna is located on a second surface of the first substrate, wherein the second surface of the first substrate faces away from the first surface of the first substrate, and

at least a portion of the antenna is located in the second encapsulation region.

2. The organic light-emitting display of claim 1 , wherein a width of the first encapsulation region in a region of the first substrate is different from a width of the first encapsulation region in another region of the first substrate.

3. The organic light-emitting display of claim 1 , wherein the first encapsulation region is located in an inner side of the first substrate, and the second encapsulation region is located in an outer side of the first substrate.

4. The organic light-emitting display of claim 1 , wherein a portion of the first encapsulation region is interposed between the pixel region and the second encapsulation region.

5. The organic light-emitting display of claim 1 , wherein the dummy metal is not located in the second encapsulation region.

6. The organic light-emitting display of claim 1 , further comprising a plurality of openings defined in the insulating layer and comprising:

a plurality of first openings which is defined in the first encapsulation region; and

a plurality of second openings which is defined in the second encapsulation region,

wherein a size of each of the plurality of first openings is different from a size of each of the plurality of second openings.

7. The organic light-emitting display of claim 6 , wherein a ratio of a total area of vertical surfaces of the second openings to a planar area of the second encapsulation region is different from a ratio of a total area of vertical surfaces of the first openings to a planar area of the first encapsulation region.

8. The organic light-emitting display of claim 1 , wherein the first encapsulation region surrounds the antenna.

9. The organic light-emitting display of claim 8 , wherein at least a portion of a boundary line between the first encapsulation region and the second encapsulation region is staircase-shaped.

10. The organic light-emitting display of claim 1 , further comprising a support layer which is located on the first substrate, located in the pixel region and the first encapsulation region, and includes a conductive material,

wherein the organic light-emitting device and the sealant are located in the first surface of the first substrate, and

the support layer is located in the second surface of the first substrate, wherein the second surface of the first substrate faces away from the first surface of the first substrate.

11. The organic light-emitting display of claim 10 , wherein the support layer is not located in the second encapsulation region.

12. The organic light-emitting display of claim 1 , wherein the organic light-emitting device comprises:

a first electrode;

a second electrode which is located on the first electrode; and

an organic light-emitting layer which is interposed between the first electrode and the second electrode,

wherein the dummy metal includes the same material as any one of the first electrode and the second electrode.

13. The organic light-emitting display of claim 1 , further comprising a thin-film transistor which is located in the pixel region of the first substrate,

wherein

the thin-film transistor comprises a gate electrode, a source electrode and a drain electrode, and

the dummy metal includes the same material as at least one of the gate electrode, the source electrode and the drain electrode.

14. The organic light-emitting display of claim 1 , further comprising a second substrate which faces the first substrate in a plan view and is coupled to the first substrate by the sealant.

15. An organic light-emitting display comprising:

a substrate which comprises:

a pixel region; and

an encapsulation region which surrounds the pixel region;

an organic light-emitting device which is located in the pixel region;

a sealant which is located in the encapsulation region;

a dummy metal which is interposed between the substrate and the sealant;

an antenna which is located on the substrate; and

an insulating layer which is interposed between the substrate and the sealant, wherein an opening is defined by the insulating layer, and at least a portion of the antenna overlaps the opening,

wherein

a width of a region including the dummy metal in a region of the substrate is smaller than a width of the region including the dummy metal in another region of the substrate,

the encapsulation region comprises a single first encapsulation region, and a single second encapsulation region which is contiguous to the first encapsulation region and abutting a periphery of the first encapsulation region,

the organic light-emitting device and the sealant are located on a first surface of the substrate, and

the antenna is located on a second surface of the substrate, wherein the second surface of the substrate faces away from the first surface of the substrate, and wherein the antenna does not overlap the dummy metal.

16. An organic light-emitting display comprising:

a substrate;

an organic light-emitting device which is located in a first surface of the substrate in a pixel region;

a sealant which is located on the first surface of the substrate and surrounds the organic light-emitting device;

an electrically isolated dummy metal which is interposed between the substrate and the sealant;

an antenna which is located on a second surface of the substrate, wherein the second surface of the substrate faces away from the first surface of the substrate, and wherein the antenna does not overlap the dummy metal; and
