Abstract

A display panel comprising a display region, a non-display region around the display region, and a transition display region located between the display region and the non-display region, wherein the display panel comprises: a display base plate; an encapsulation cover plate located on the display base plate and configured to seal the display base plate; a support column disposed between the display base plate and the encapsulation cover plate, and configured to support the encapsulation cover plate. In the transition display region, a surface of the encapsulation cover plate close to the display base plate is provided with a first groove, and/or a surface of the display base plate close to the encapsulation cover plate is provided with a second groove.

First claim

What is claimed is:

1 . A display panel comprising a display region, a non-display region around the display region, and a light-transmitting region located in the display region, wherein the display panel comprises:
a display base plate; an encapsulation cover plate, located on the display base plate and configured to seal the display base plate; a support column, disposed between the display base plate and the encapsulation cover plate, and configured to support the encapsulation cover plate; and wherein the support column further comprises a second annular support column located in the display region close to the light-transmitting region and arranged around the light-transmitting region.

2 . The display panel of claim 1 , wherein the support column comprises a first annular support column located in the display region close to the transition display region and arranged around the transition display region.

3 . The display panel of claim 2 , wherein the first annular support column is an annular support column arranged concentrically with a center of the transition display region.

4 . The display panel of claim 2 , wherein the first annular support column comprises at least two arc-shaped sub-support columns spaced apart from each other.

5 . The display panel of claim 1 , wherein a depth of the first groove is greater than or equal to 10 μm and less than or equal to 100 μm.

6 . The display panel of claim 1 , wherein a depth of the second groove is greater than or equal to 10 μm and less than or equal to 100 μm.

7 . The display panel of claim 1 , further comprising a light-transmitting region located in the display region,
wherein, in the light-transmitting region, the surface of the encapsulation cover plate close to the display base plate is provided with a third groove.

8 . The display panel of claim 1 , further comprising a light-transmitting region located in the display region,
wherein, in the light-transmitting region, the surface of the display base plate close to the encapsulation cover plate is provided with a fourth groove.

9 . The display panel of claim 1 , further comprising a transition display region located between the display region and the non-display region
wherein, in the transition display region, a surface of the encapsulation cover plate close to the display base plate is provided with a first groove, and/or a surface of the display base plate close to the encapsulation cover plate is provided with a second groove.

10 . The display panel of claim 9 , wherein the second annular support column comprises at least two arc-shaped sub-support columns spaced apart from each other.

11 . The display panel of claim 7 , wherein a depth of the third groove is greater than or equal to 10 μm and less than or equal to 100 μm.

12 . The display panel of claim 8 , wherein a depth of the fourth groove is greater than or equal to 10 μm and less than or equal to 100 μm.

13 . The display panel of claim 1 , further comprising a light-transmitting region located in the display region and a light modulation layer located in the light-transmitting region,
wherein the light modulation layer is sandwiched between any adjacent light-transmitting layers covering the light-transmitting region, the light modulation layer is configured that at least a part of the light modulation layer is capable of improving a light transmittance of light with a preset wavelength between the adjacent light-transmitting layers sandwiching the light modulation layer, and a refractive index of the light modulation layer is between refractive indices of the adjacent light-transmitting layers sandwiching the light modulation layer.

14 . The display panel of claim 13 , wherein the light modulation layer is sandwiched between the encapsulation cover plate covering the light-transmitting region and the display base plate, and the refractive index of the light modulation layer is between the refractive index of the encapsulation cover plate and the refractive index of the display base plate.

15 . The display panel of claim 1 , wherein a material of the support column comprises at least one of photosensitive siloxane and photosensitive polyimide photoresist.

16 . The display panel of claim 1 , wherein at least part of the support column is doped with at least one of a rigid bar and a rigid particle.

17 . The display panel of claim 13 , wherein the light-transmitting region comprises a blind hole structure;
wherein the display base plate comprises a substrate; wherein the light modulation layer is arranged between the substrate and the encapsulation cover plate; wherein the refractive index of the light modulation layer is between the refractive index of the substrate and the refractive index of the encapsulation cover plate.

18 . The display panel of claim 1 , wherein the light-transmitting region comprises a blind hole structure, the display base plate comprises a substrate, and the substrate is provided with a fifth groove.

19 . The display panel of claim 18 , wherein a depth of the fifth groove is greater than or equal to 10 μm and less than or equal to 100 μm.

20 . A display device, comprising:
a display panel of claim 1 ; and a photosensitive assembly disposed corresponding to the light-transmitting region of the display panel; wherein the display panel comprises a first surface and a second surface opposite to the first surface; wherein the first surface is a display surface; and wherein the photosensitive assembly is located on a side of the display panel where the second surface is located.

21 . A display panel comprising a display region, a non-display region around the display region, and a light-transmitting region located in the display region, and a light modulation layer located in the light-transmitting region, wherein the display panel comprises:
a display base plate; an encapsulation cover plate, located on the display base plate and configured to seal the display base plate; a support column, disposed between the display base plate and the encapsulation cover plate, and configured to support the encapsulation cover plate; and wherein the light-transmitting region comprises a blind hole structure, the display base plate comprises a substrate; and the light modulation layer is arranged between the substrate and the encapsulation cover plate.

22 . The display panel of claim 21 , further comprising a transition display region located between the display region and the non-display region,
wherein, in the transition display region, a surface of the encapsulation cover plate close to the display base plate is provided with a first groove, and/or a surface of the display base plate close to the encapsulation cover plate is provided with a second groove.
