Abstract

An organic light-emitting display apparatus includes a first substrate, a display unit that defines an active area on the first substrate, a second substrate on the display unit, a circuit pattern on outer sides of the active area on the first substrate, a sealant between the first substrate and the second substrate, the sealant adhering the first substrate to the second substrate and overlapping at least a part of the circuit pattern, and a detecting unit that overlaps the at least a part of the circuit pattern and detects whether the circuit pattern is damaged.

Claims (27)

1. An organic light-emitting display apparatus, comprising:

a first substrate;

a display unit that defines an active area on the first substrate;

a second substrate on the display unit;

a circuit pattern on outer sides of the active area on the first substrate;

a sealant between the first substrate and the second substrate, the sealant adhering the first substrate to the second substrate and overlapping at least a part of the circuit pattern; and

a detecting unit that overlaps at least a part of the circuit pattern and detects whether the circuit pattern is damaged,

wherein the detected unit includes a plurality of thin film transistor that are respectively electrically connected to a plurality of points of the connection line.

2. The organic light-emitting display apparatus as claimed in claim 1 , wherein the circuit pattern includes:

a signal line; and

a connection line that electrically connects the signal line and the display unit.

3. The organic light-emitting display apparatus as claimed in claim 2 , wherein:

the display unit includes:

a first electrode;

a second electrode; and

an intermediate layer between the first electrode and the second electrode, and

the signal line is electrically connected to the second electrode via the connection line.

4. The organic light-emitting display apparatus as claimed in claim 3 , wherein the connection line is formed of a same material as the first electrode.

5. The organic light-emitting display apparatus as claimed in claim 2 , wherein the sealant overlaps a part of the connection line.

6. The organic light-emitting display apparatus as claimed in claim 5 , wherein:

at least a part of the detecting unit is under an area where the connection line overlaps the sealant, and

the detecting unit is electrically connected to the connection line and detects whether the connection line is damaged.

7. The organic light-emitting display apparatus as claimed in claim 2 , wherein:

the connection line and the signal line are positioned on different layers from each other, and

at least a part of the connection line overlaps the signal line.

8. The organic light-emitting display apparatus as claimed in claim 2 further comprising an insulating layer between the sealant and the signal line.

9. The organic light-emitting display apparatus as claimed in claim 2 , wherein a thickness of the connection line is in a range of about 10% to about 30% of a thickness of the signal line.
