Abstract

Embodiments of the present invention disclose a flexible display panel. The flexible display panel at least comprises an display area, a fanout area and a driver circuit area, wherein the fanout area is positioned between the display area and the driver circuit area to connect the display area with the driver circuit area, and the fanout area comprises at least one zig-zag fanout wire, each of which comprises a plurality of fanout wire segments divided by bending points. In the technical solutions of the present invention, by utilizing a zig-zag wiring manner, damage to metal wires when bending is reduced, bending resistance of the fanout area is improved and damage to the screen when bending the flexible display panel is avoided or reduced.

First claim

What is claimed is:

1. A flexible display panel comprising at least a display area, a fanout area and a driver circuit area, the fanout area being positioned between the display area and the driver circuit area to connect the display area with the driver circuit area, wherein
the fanout area comprises at least one zig-zag fanout wire, each of which comprises a plurality of fanout wire segments divided by bending points;
wherein the driver circuit area is disposed at at least one of four corners of the display area; and
wherein the driver circuit area comprises a driver IC and/or a gate driver on array circuit.

2. The flexible display panel of claim 1 , wherein one zig-zag fanout wire of the fanout area is used to connect one pin of the driver IC with the display area, or one zig-zag fanout wire of the fanout area is used to connect one pin of the gate driver on array circuit with the display area.

3. The flexible display panel of claim 1 , wherein the fanout wire segments positioned on opposite sides of the bending point are made of one kind of metal material or two kinds of metal material.

4. The flexible display panel of claim 1 , wherein the fanout wire segments positioned on opposite sides of the bending point are positioned in different layers.

5. The flexible display panel of claim 4 , wherein the fanout wire segments positioned on opposite sides of each bending point of one zig-zag fanout wire are electrically connected through a via hole at the bending point so that the whole zig-zag fanout wire are electrically conductive.

6. The flexible display panel of claim 4 , wherein the fanout wire segments of one zig-zag fanout wire are located alternately in two layers.

7. The flexible display panel of claim 4 , wherein the fanout wire segments of different zig-zag fanout wires are capable of being located in the same layer.

8. The flexible display panel of claim 1 , wherein the driver IC or the gate driver on array circuit is disposed at any position outside and near to each of the four corners of the display area.

9. The flexible display panel of claim 1 , wherein in the fanout area, the fanout wire segments in different layers intersect with each other respectively and the fanout wire segments in the same layer are parallel with each other respectively.

10. A display apparatus comprising the display panel of claim 1 .

11. The display apparatus of claim 10 , wherein one zig-zag fanout wire of the fanout area is used to connect one pin of the driver IC with the display area, or one zig-zag fanout wire of the fanout area is used to connect one pin of the gate driver on array circuit with the display area.

12. The display apparatus of claim 10 , wherein the fanout wire segments positioned on opposite sides of the bending point are made of one kind of metal material or two kinds of metal material.

13. The display apparatus of claim 10 , wherein the fanout wire segments positioned on opposite sides of the bending point are positioned in different layers.

14. The display apparatus of claim 13 , wherein the fanout wire segments positioned on opposite sides of each bending point of one zig-zag fanout wire are electrically connected through a via hole at the bending point so that the whole zig-zag fanout wire are electrically conductive.

15. The display apparatus of claim 13 , wherein the fanout wire segments of one zig-zag fanout wire are located alternately in two layers.

16. The display apparatus of claim 13 , wherein the fanout wire segments of different zig-zag fanout wires are capable of being located in the same layer.
