Abstract

A display device is provided. The display device includes a cover plate, a first adhesive layer, a glass layer, a second adhesive layer, and a buffer layer. The first adhesive layer, the glass layer, and the second adhesive layer are sequentially disposed on a side of the cover plate. The glass layer is made of reinforced ultra-thin glass. Peripheral edges of the glass layer are indented with respect to peripheral edges of the first adhesive layer and the second adhesive layer to form an indented region. The buffer layer is disposed in the indented region.

Claims (34)

1. A display device, comprising:

a cover plate;

a first adhesive layer disposed directly on a side of the cover plate;

a glass layer disposed on the first adhesive layer and made of reinforced ultra-thin glass;

a second adhesive layer disposed on the glass layer, wherein peripheral edges of the glass layer are indented with respect to peripheral edges of the first adhesive layer and the second adhesive layer to form an indented region; and

a buffer layer disposed in the indented region.

2. The display device according to claim 1 , wherein the buffer layer is made of a polymer.

3. The display device according to claim 1 , wherein the first adhesive layer and the second adhesive layer are made of an optically clear adhesive.

4. The display device according to claim 1 , wherein the display device has a main display area and an edge area and further comprises:

a light shielding layer disposed on a side of the cover plate close to the first adhesive layer in the edge area.

5. The display device according to claim 4 , wherein an orthographic projection of the light shielding layer on the cover plate covers an orthographic projection of the indented region on the cover plate.

6. The display device according to claim 1 , further comprising a display module, wherein the display module comprises:

a function control layer disposed on a side of the glass layer away from the cover plate; and a display layer disposed on a side of the function control layer away from the glass layer.

7. The according to claim 6 , wherein the display layer is a flexible organic light-emitting diode (OLED) display panel, and the function control layer is a touch layer or a polarizer.

8. The display device according to claim 6 , further comprising:

a back plate layer disposed on a side of the display module away from the cover plate.

9. A display device, comprising:

a cover plate;

a first adhesive layer disposed directly on a side of the cover plate;

a glass layer disposed on the first adhesive layer, a second adhesive layer disposed on the glass layer, wherein one or more edges of the glass layer are indented with respect to corresponding edges of the first adhesive layer and the second adhesive layer to form one or more indented regions; and

a buffer layer disposed in each of the indented regions.

10. The display device according to claim 9 , wherein the glass layer is made of reinforced ultra-thin glass.

11. The display device according to claim 10 , wherein the edges of the glass layer are indented with respect to corresponding edges of the first adhesive layer and the second adhesive layer by a distance greater than or equal to 0.25 mm.

12. The display device according to claim 9 , wherein the buffer layers are made of a polymer.

13. The display device according to claim 9 , wherein the first adhesive layer and the second adhesive layer are made of an optically clear adhesive.

14. The display device according to claim 9 , wherein the display device has a main display area and an edge area and further comprises:

a light shielding layer disposed on a side of the cover plate close to the first adhesive layer in the edge area.

15. The according to claim 14 , wherein an orthographic projection of the light shielding layer on the cover plate covers orthographic projections of the indented regions on the cover plate.

16. The display device according to claim 9 , further comprising a display module, wherein the display module comprises:

a function control layer disposed on a side of the glass layer away from the cover plate; and

a display layer disposed on a side of the function control layer away from the glass layer.

17. The display device according to claim 16 , wherein the display layer is a flexible organic light-emitting diode (OLED) display panel, and the function control layer is a touch layer or a polarizer.

18. The display device according to claim 16 , further comprising:

a back plate layer disposed on a side of the display module away from the cover plate.
