Display panel and display device
The application discloses a display panel and a display device. The display panel includes a substrate. The substrate includes a bonding region and a bend region connected to the bonding region. The substrate further includes a support block disposed corresponding to the bend region and the bonding region and disposed on a side of the substrate facing away from a display surface. The maximum thickness of the support block located in the bonding region is greater than the maximum thickness of the support block located in the bend region.
1. A display panel, comprising:
a substrate, comprising a bonding region and a bend region connected to the bonding region; and
a support block, disposed corresponding to the bend region and the bonding region and disposed on a side of the substrate facing away from a display surface, wherein a maximum thickness of the support block located in the bonding region is greater than a maximum thickness of the support block located in the bend region.
2. The display panel of claim 1 , wherein
a thickness of a side, away from the bonding region, of the support block located in the bend region is less than or equal to a thickness of any other part of the support block located in the bend region.
3. The display panel of claim 2 , wherein the maximum thickness of the support block located in the bend region is less than or equal to the minimum thickness of the support block located in the bonding region.
4. The display panel of claim 3 , wherein
along a direction from the bend region to the bonding region, a thickness, perpendicular to the substrate, of the support block located in the bend region increases gradually.
5. The display panel of claim 4 , wherein
the thickness of the support block located in the bend region increases continuously or stepwise.
6. The display panel of claim 3 , wherein
a thickness of the support block located in the bend region changes in a wave shape.
7. The display panel of claim 2 , wherein
the thickness of the side, away from the bonding region, of the support block located in the bend region is less than or equal to a minimum thickness of the support block located in the bonding region, and a minimum thickness of the support block located in the bend region is in a range of 5-30 μm.
8. The display panel of claim 1 , wherein the support block located in the bend region is uniform in thickness.
9. The display panel of claim 1 , wherein a thickness of a side, away from the bonding region, of the support block located in the bend region is less than or equal to a minimum thickness of the support block located in the bonding region.
10. The display panel of claim 9 , wherein the maximum thickness of the support block located in the bend region is less than or equal to the minimum thickness of the support block located in the bonding region.
11. The display panel of claim 10 , wherein
along a direction from the bend region to the bonding region, a thickness, perpendicular to the substrate, of the support block located in the bend region increases gradually.
12. The display panel of claim 11 , wherein
the thickness of the support block located in the bend region increases continuously or stepwise.
13. The display panel of claim 10 , wherein
a thickness of the support block located in the bend region changes in a wave shape.
14. The display panel of claim 1 , wherein
at least part of the support block located in the bonding region is uniform in thickness.
15. The display panel of claim 14 , wherein
the support block located in the bonding region is uniform in thickness.
16. The display panel of claim 14 , wherein
along a direction from the bend region to the bonding region, a thickness of the support block located in the bonding region increases and then remains unchanged.
17. The display panel of claim 1 , wherein
the substrate further comprises a first region, and the first region is located on a side of the bend region away from the bonding region; and
the display panel further comprises a support layer disposed corresponding to the first region and disposed on the side of the substrate facing away from the display surface, and with the bend region being bent, the support block located in the bonding region and having the maximum thickness abuts a side of the support layer facing away from the substrate.
18. The display panel of claim 17 , further comprising a buffer layer and a heat dissipation layer, wherein the buffer layer is disposed on the side of the support layer facing away from the substrate and the heat dissipation layer is disposed on a side of the buffer layer facing away from the support layer.
19. The display panel of claim 17 , wherein with the bend region being bent, the bonding region is disposed in parallel with the first region.
20. A display device, comprising the display panel of claim 1 .
