Abstract
Official abstract text for this publication.
The present disclosure relates a display device, including a flexible display panel with a bendable region and a flexible support attached to a back side of the flexible display panel, the flexible support includes a flexible support body, and a first part of the flexible support body corresponding to the bendable region is provided with a concave structure.
First claim
Opening claim text (preview).
What is claimed is: 1. A display device, comprising a flexible display panel with a bendable region and a flexible support attached to a back side of the flexible display panel, wherein the flexible support comprises a flexible support body, a first part of the flexible support body corresponding to the bendable region is provided with a concave structure, and a second part corresponding to an unbendable region of the flexible display panel, wherein an orthographic projection of the flexible support body on the plane in which the flexible display panel is located exceeds the coverage range of the flexible display panel at least on one side of the orthographic projection of the flexible support body. 2. The display device according to claim 1 , wherein a depth of the concave structure is less than a thickness of the flexible support body. 3. The display device according to claim 2 , wherein the concave structure comprises a strip groove, and a length extension direction of the strip groove is parallel to a bending axis of the bendable region. 4. The display device according to claim 3 , wherein an opening area of the strip groove is larger than a bottom area of the strip groove. 5. The display device according to claim 4 , wherein a cross section of the strip groove perpendicular to the length extension direction is V-shape, trapezoidal or U-shape. 6. The display device according to claim 3 , wherein the strip groove is at least partially filled with a buffer material. 7. The display device according to claim 1 , wherein a depth of the concave structure is equal to a thickness of the flexible support body. 8. The display device according to claim 7 , wherein the concave structure comprises a strip groove, a length extension direction of the strip groove is perpendicular to a bending axis of the bendable region. 9. The display device according to claim 7 , wherein the concave structure comprises a through hole penetrating the flexible support body in a thickness direction. 10. The display device according to claim 9 , wherein a cross section of the through hole along a direction perpendicular to the thickness direction is rectangular, rhombic or hexagonal. 11. The display device according to claim 1 , wherein the flexible support body is a metal film layer. 12. The display device according to claim 1 , wherein the flexible support body further comprises an adhesive layer, the flexible support body is attached to the flexible display panel through the adhesive layer. 13. The display device according to claim 12 , wherein the adhesive layer is a pressure sensitive adhesive layer. 14. The display device according to claim 1 , wherein a thickness of the flexible support ranges from 15 um to 500 um. 15. The display device according to claim 14 , wherein the thickness of the flexible support ranges from 50 um to 250 um. 16. The display device according to claim 14 , wherein the thickness of the flexible support body ranges from 15 um to 150 um. 17. The display device according to claim 16 , wherein the thickness of the flexible support body ranges from 30 um to 50 um. 18. The display device according to claim 1 , wherein the display device is a foldable display device.
