Abstract

A flexible display module includes a flexible substrate, a display layer disposed on the flexible substrate, a protective layer disposed on the display layer, a strengthening layer disposed between the display layer and the protective layer, the modulus of the strengthening layer being greater than or equal to the modulus of any of the layers in the flexible display module.

Claims (16)

1. A flexible display module, comprising: a flexible substrate, a display layer disposed on the flexible substrate, a protective layer disposed on the display layer, a strengthening layer disposed between the display layer and the protective layer, modulus of the strengthening layer being greater than or equal to modulus of any of the layers in the flexible display module, the strengthening layer needs to be able to withstand bending of 100,000 times or more with a radius of 1 mm-15 mm, modulus of the strengthening layer ranges from 10 Gpa to 200 Gpa, and material of the strengthening layer is inorganic fiber-reinforced organic material.

2. The flexible display module according to claim 1 , further comprising a polarizing layer disposed between the display layer and the protective layer.

3. The flexible display module according to claim 2 , further comprising a touch layer disposed between the polarizing layer and the protective layer.

4. The flexible display module according to claim 2 , wherein the strengthening layer is adjacent to the display layer.

5. The flexible display module according to claim 1 , wherein thickness of the strengthening layer ranges from 10 μm to 150 μm.

6. The flexible display module according to claim 5 , wherein the thickness of the strengthening layer ranges from 30 μm to 120 μm.

7. The flexible display module according to claim 6 , wherein the thickness of the strengthening layer ranges from 30 μm to 100 μm.

8. The flexible display module according to claim 1 , wherein transmittance of the strengthening layer is greater than 90%.

9. The flexible display module according to claim 1 , wherein the strengthening layer is fixed to an adjacent layer by a glue material.

10. A display device comprising the flexible display module according to claim 1 .

11. The flexible display module according to claim 2 , further comprising a touch layer disposed between the polarizing layer and the display layer.

12. The flexible display module according to claim 3 , wherein the strengthening layer is adjacent to the display layer.

13. The flexible display module according to claim 2 wherein thickness of the strengthening layer ranges from 10 μm to 150 μm.

14. The flexible display module according to claim 3 wherein thickness of the strengthening layer ranges from 10 μm to 150 μm.

15. A display device comprising the flexible display module according to claim 2 .

16. A display device comprising the flexible display module according to claim 3 .
