Abstract

The present disclosure describes a flexible display panel and display apparatus. The flexible display panel comprises: a flexible substrate; an array layer located on the flexible substrate; a display layer located on a side of the array layer facing away from the flexible substrate, the display layer comprising a plurality of light-emitting devices; a shielding film located on a side of the flexible substrate facing away from the array layer; the flexible display panel comprises a bendable area, the shielding film has a plurality of hollow portions at least at the bendable area. The present disclosure can shield the film to relieve the bending stress when the flexible display panel is bent, thereby avoiding the crease of the flexible display panel in the bending area, and achieving performance reliability of the flexible display panel.

Claims (19)

1. A flexible display panel, comprising:

a flexible substrate;

an array layer located on the flexible substrate;

a display layer located on a side of the array layer facing away from the flexible substrate, the display layer comprising a plurality of light-emitting devices; and

a shielding film located on a side of the flexible substrate facing away from the array layer,

wherein the flexible display panel has a bendable area, and the shielding film has a plurality of hollow portions, at least a portion of the plurality of hollow portions being in the bendable area.

2. The flexible display panel according to claim 1 , wherein the shielding film has a thickness between 100 μm and 1 mm.

3. The flexible display panel according to claim 2 , wherein each of the plurality of hollow portions has a shape selected from at least one of a rhombus, a hexagon, a circle, or an ellipse.

4. The flexible display panel according to claim 3 , wherein each of the plurality of hollow portions has a size between 0.1 mm and 1 cm.

5. The flexible display panel according to claim 2 , wherein the shielding film is a mesh shielding film.

6. The flexible display panel according to claim 5 , wherein the mesh shielding film is stretching film is stretchable in one stretching direction.

7. The flexible display panel according to claim 6 , wherein the mesh shielding film comprises a unidirectional stretching pattern along the stretching direction.

8. The flexible display panel according to claim 5 , wherein the mesh shielding film is stretchable in two independent stretching directions, a first stretching direction and a second stretching direction, and

the first stretching direction is perpendicular to the second stretching direction.

9. The flexible display panel according to claim 8 , wherein the mesh shielding film comprises a first unidirectional stretching pattern extending along the first stretching direction, and a second unidirectional stretching pattern extending along the second stretching direction.

10. The flexible display panel according to claim 1 , further comprising an adhesive layer,

wherein the adhesive layer is disposed between the shielding film and the flexible substrate.

11. The flexible display panel according to claim 10 , wherein the adhesive layer comprises a PET mesh double-side tape or an optical tape.

12. A display apparatus, comprising the flexible display panel according claim 1 .
