Abstract

A structure for repairing a line defect in which a short can be easily repaired using an adjacent wiring line despite limited repairing space and a method of repairing the defect are disclosed.

Claims (37)

1. A structure for repairing a short defect between first and second wiring lines of an organic light emitting display, the structure comprising:

an isolated part of the second wiring line, wherein the isolated part of the second wiring line comprises the short between the first and second wiring lines;

first and second remaining parts of the second wiring line, wherein the first and second remaining parts of the second wiring line are electrically isolated from the isolated part of the second wiring line;

an isolated part of a third wiring line, wherein the isolated part of the third wiring line is substantially adjacent to the isolated part of the second wiring line;

first and second remaining parts of the third wiring line, wherein the first and second remaining parts of the third wiring line are electrically isolated from the isolated part of the third wiring line and from one another; and

a first repair pattern electrically coupling the first and second remaining parts of the second wiring line to the isolated part of the third wiring line,

wherein the third wiring line is configured to receive signals from both of the first and second remaining parts of the third wiring line.

2. The structure as claimed in claim 1 , wherein the second and third wiring lines are disposed to cross the first wiring line with an insulating layer interposed therebetween.

3. The structure as claimed in claim 2 , wherein the first wiring line is disposed under the insulating layer.

4. The structure as claimed in claim 2 , wherein the second and third wiring lines are disposed parallel on the insulating layer.

5. The structure as claimed in claim 1 , further comprising:

an isolated part of a fourth wiring line, wherein the isolated part of the fourth wiring line is substantially adjacent to the isolated part of the third wiring line;

first and second remaining parts of the fourth line, wherein the first and second remaining parts of the fourth line are electrically isolated from the isolated part of the fourth wiring line; and

a second repair pattern electrically coupling the first and second remaining parts of the third wiring line to the isolated part of the fourth wiring line.

6. The structure as claimed in claim 5 , wherein the fourth wiring line is configured to receive signals from both of the first and second remaining parts of the fourth wiring line.

7. The structure as claimed in claim 5 , further comprising a third repair pattern electrically coupling the first and second remaining parts of the fourth wiring line.

8. A method of repairing a short defect between first and second wiring lines of an organic light emitting display, the method comprising:

cutting the second wiring line so that an isolated part of the second wiring line comprising the short is isolated from first and second remaining parts of the second wiring line;

cutting a third wiring line so that an isolated part of the third wiring line is adjacent to the isolated part of the second wiring line, wherein the isolated part of the third wiring line is isolated from first and second remaining parts of the third wiring line, wherein the first and second remaining parts of the third wiring line are isolated from one another; and

forming a first repair pattern to electrically couple the first and second remaining parts of the second wiring line to the isolated part of the third wiring line,

wherein the third wiring line is configured to receive signals from both of the first and second remaining parts of the third wiring line.

9. The method as claimed in claim 8 , further comprising electrically coupling the first and second remaining parts of the third wiring line using a fourth wiring line adjacent to the third wiring line.

10. The method as claimed in claim 9 , wherein coupling the first and second remaining parts of the third wiring line comprises:

cutting the fourth wiring line so that an isolated part of the fourth wiring line is adjacent to the isolated part of the third wiring line, wherein the isolated part of the fourth wiring line is isolated from first and second remaining parts of the fourth wiring line; and

forming a second repair pattern to electrically couple the first and second remaining parts of the third wiring line to the isolated part of the fourth wiring line.

11. The method as claimed in claim 10 , wherein the fourth wiring line is configured to receive signals from both of the first and second remaining parts of the fourth wiring line.

12. The method as claimed in claim 10 , further comprising forming a third repair pattern to electrically couple the first and second remaining parts of the fourth wiring line.

13. A method of repairing an open defect in a first wiring line of an organic light emitting display, the first wiring line comprising first and second parts separated by the open, the method comprising:

cutting a second wiring line so that an isolated part of the second wiring line is adjacent to the open in the first wiring line, wherein the isolated part of the second wiring line is isolated from first and second remaining parts of the second wiring line and wherein the first and second remaining parts of the second wiring line are isolated from one another; and

forming a first repair pattern to electrically couple the first and second parts of the first wiring line to the isolated part of the second wiring line,

wherein the second wiring line is configured to receive signals from both of the first and second remaining parts of the second wiring line.

14. The method as claimed in claim 13 , further comprising electrically coupling the first and second remaining parts of the second wiring line using a third wiring line.

15. The method as claimed in claim 14 , wherein coupling the first and second remaining parts of the second wiring line comprises:

cutting the third wiring line so that an isolated part of the third wiring line is adjacent to the isolated part of the second wiring line, wherein the isolated part of the third wiring line is isolated from first and second remaining parts of the third wiring line; and

forming a second repair pattern to electrically couple the first and second remaining parts of the second wiring line to the isolated part of the third wiring line.

16. The method as claimed in claim 15 , wherein the third wiring line is configured to receive signals from both of the first and second remaining parts of the third wiring line.

17. The method as claimed in claim 15 , further comprising forming a third repair pattern to electrically couple the first and second remaining parts of the third wiring line.
