Abstract

Disclosed are a display panel in which all or some portions of an inspection pad and an inspection wire for inspection of a panel are formed in the display panel, and a display device.

First claim

What is claimed is:

1. A display device comprising:
two or more driver integrated circuits for outputting a signal for display of an image; and
a display panel comprising two or more inspection pads arranged between two of the two or more driver integrated circuits and at least one inspection wire arranged between two of the two or more driver integrated circuits,
wherein a first end of a first inspection wire is connected to a first inspection pad of the two or more inspection pads and a second end of the first inspection wire, opposite to the first end of the first inspection wire, is connected to a second inspection pad of the two or more inspection pads, and wherein the first inspection pad, the second inspection pad, and the first inspection wire are not used to drive the finally finished display device.

2. The display device of claim 1 , wherein the first inspection wire is arranged between locations of the different inspection pads and a peripheral location of an active area of the display panel.

3. The display device of claim 1 , wherein the display panel further comprises a second inspection wire arranged between two of the two or more driver integrated circuits, wherein a first end of the second inspection wire is connected to an inspection pad of the two or more inspection pads and a second end of the second inspection wire, opposite the first end of the second inspection wire, is not connected to an inspection pad of the two or more inspection pads.

4. The display device of claim 3 , wherein the second inspection wire is arranged between the inspection pad connected to the second inspection wire and a corner location of the display panel.

5. The display device of claim 4 , wherein the second end of the second inspection wire is broken at a corner of the display panel.

6. The display device of claim 3 , wherein a plurality of link lines are arranged between the second inspection wire or the inspection pads arranged between the two of the two or more driver integrated circuits.

7. The display device of claim 3 , wherein the display panel further comprises a third inspection pad, wherein the third inspection pad is not connected to the first inspection wire or the second inspection wire.

8. The display device of claim 1 , wherein the two or more inspection pads are arranged in a single row.

9. The display device of claim 1 , wherein the two or more inspection pads are arranged in multiple rows.

10. The display device of claim 1 , wherein the first end of the first inspection wire is directly connected to the first inspection pad of the two or more inspection pads, and the second end of the first inspection wire is directly connected to the second inspection pad of the two or more inspection pads.

11. A display panel comprising:
a first line arranged in a first direction;
a second line arranged in a second direction;
two or more inspection pads arranged between two driver integrated circuits; and
at least one first inspection wire arranged between the two driver integrated circuits,
wherein a first end of the first inspection wire is connected to a first inspection pad of the two or more inspection pads and a second end of the first inspection wire, opposite to the first end of the first inspection wire, is connected to a second inspection pad of the two or more inspection pads, and wherein the first inspection pad, the second inspection pad, and the first inspection wire are not used to drive the finally finished display panel.

12. The display panel of claim 11 , wherein the first end of the first inspection wire is directly connected to the first inspection pad of the two or more inspection pads, and the second end of the first inspection wire is directly connected to the second inspection pad of the two or more inspection pads.

13. The display panel of claim 11 , wherein the first inspection wire is arranged between locations of the different inspection pads and a peripheral location of an active area of the display panel.

14. The display panel of claim 11 , further comprising a second inspection wire arranged between two of the two or more driver integrated circuits, wherein a first end of the second inspection wire is connected to an inspection pad of the two or more inspection pads and a second end of the second inspection wire, opposite the first end of the second inspection wire, is not connected to an inspection pad of the two or more inspection pads.

15. The display panel of claim 14 , wherein the second inspection wire is arranged between the inspection pad connected to the second inspection wire and a corner location of the display panel.

16. The display panel of claim 15 , wherein the second end of the second inspection wire is broken at a corner of the display panel.

17. The display panel of claim 14 , wherein a plurality of link lines are arranged between the second inspection wire or the inspection pads arranged between the two of the two or more driver integrated circuits.

18. The display panel of claim 14 , wherein the display panel further comprises a third inspection pad, wherein the third inspection pad is not connected to the first inspection wire or the second inspection wire.

19. The display panel of claim 11 , wherein the two or more inspection pads are arranged in a single row.

20. The display panel of claim 11 , wherein the two or more inspection pads are arranged in multiple rows.
