Abstract

The disclosure provides a display panel and a flexible display device. The display panel includes: a non-bending region, which includes a first non-bending region and a second non-bending region; a bending region, configured to connect with the first non-bending region and the second non-bending region; a supporting structure, between the first non-bending region and the second non-bending region and close to the bending region, where the supporting structure is configured to support the first non-bending region and the second non-bending region; and a buffer structure, on at least one edge of the supporting structure close to the bending region, and configured to buffer pressing of the edge of the supporting structure on the non-bending region.

Claims (19)

1. A display panel, comprising:

a non-bending region, comprising a first non-bending region and a second non-bending region;

a bending region, configured to connect with the first non-bending region and the second non-bending region;

a supporting structure, between the first non-bending region and the second non-bending region and close to the bending region, wherein the supporting structure is configured to support the first non-bending region and the second non-bending region; and

a buffer structure, on at least one edge of the supporting structure close to the bending region, and configured to buffer pressing of the edge of the supporting structure on the non-bending region;

wherein the buffer structure comprises a slope structure on the edge of the supporting structure close to the bending region.

2. The display panel according to claim 1 , wherein two edges of the supporting structure close to the bending region are symmetrically provided with the buffer structures.

3. The display panel according to claim 1 , wherein the buffer structure comprises a buffer adhesive layer; and

Young's modulus of a material of the buffer adhesive layer is smaller than Young's modulus of a material of the supporting structure.

4. The display panel according to claim 3 , wherein the material of the buffer adhesive layer comprises a plastic resin material.

5. The display panel according to claim 1 , further comprising: a bottom film between the non-bending region and the supporting structure; wherein one side of the bottom film close to the bending region is provided with a bottom film gradual transition region, and a length of the slope structure is no smaller than a length of the bottom film gradual transition region along an arrangement direction of the first non-bending region and the bending region.

6. The display panel according to claim 1 , wherein a shape of a cross section of the slope structure along an arrangement direction of the first non-bending region and the bending region comprises at least one of a slope shape, a circular arc shape, a step shape, a zigzag shape and a wave shape.

7. The display panel according to claim 6 , wherein the shape of the cross section of the slope structure is the circular arc shape, and a center of the circular arc is on one side of the supporting structure away from the bending region.

8. The display panel according to claim 7 , wherein the center of the circular arc is inside the supporting structure.

9. The display panel according to claim 6 , wherein the shape of the cross section of the slope structure is the circular arc shape, and a center of the circular arc is on one side of the supporting structure facing the bending region.

10. The display panel according to claim 6 , wherein the shape of the cross section of the slope structure is the step shape, and the number of steps is no smaller than 1.

11. The display panel according to claim 1 , further comprising: a bonding layer between the supporting structure and the first non-bending region.

12. The display panel according to claim 11 , wherein the bonding layer comprises double-sided tape.

13. A flexible display device, comprising the display panel according to claim 1 .
