Abstract

A flexible display screen includes a main display portion, a first bending portion, a second bending portion and a corner bending portion. The main display portion includes a first side, an arc-shaped side and a second side that are connected in sequence. The first bending portion is located on a side of the main display portion where the first side is located, and is connected to the first side. The second bending portion is located on a side of the main display portion where the second side is located, and is connected to the second side. The corner bending portion is located on a side of the main display portion where the arc-shaped side is located, and is connected to the arc-shaped side. A plurality of openings are disposed in the corner bending portion, and face a bending direction of the corner bending portion.

a corner bending portion located on a side of the main display portion where the arc-shaped side is located and connected to the arc-shaped side;
wherein the first bending portion, the corner bending portion and the second bending portion are connected in sequence, and constitute a display region together with the main display portion; and a plurality of openings are disposed in the corner bending portion, and face a bending direction of the corner bending portion; and
the plurality of openings have a same shape, the plurality of openings are arranged in a plurality of rows in a radial direction of the arc-shaped side, openings in each row are arranged at intervals along an extending direction of the arc-shaped side, and the openings in each row are arranged in a same arc level along the arc-shaped side.

2. The flexible display screen according to claim 1 , wherein the corner bending portion has a wiring region and a deformation region that are sequentially disposed along a direction from the corner bending portion toward the main display portion; wherein
the deformation region is connected to the arc-shaped side, and the plurality of openings are disposed in the deformation region; and
at least one first signal line is disposed in the wiring region.

3. The flexible display screen according to claim 2 , wherein along a direction from a center of the deformation region toward the first bending portion and along a direction from the center of the deformation region toward the second bending portion,
dimensions of openings in each of at least one row along the radial direction of the arc-shaped side are reduced in sequence; and/or
dimensions of openings in each of at least one row along the extending direction of the arc-shaped side are reduced in sequence.

4. The flexible display screen according to claim 2 , wherein along a direction from a center of the deformation region toward a side boundary of the deformation region along the radial direction of the arc-shaped side and along a direction from the center of the deformation region toward another side boundary of the deformation region along the radial direction of the arc-shaped side,
dimensions, along the radial direction of the arc-shaped side, of openings arranged along the radial direction of the arc-shaped side are reduced in sequence; and/or

5. The flexible display screen according to claim 2 , wherein the deformation region includes a middle region and an edge region, and the edge region surrounds the middle region; wherein
a dimension, along the radial direction of the arc-shaped side, of an opening in the plurality of openings located in the middle region is greater than a dimension, along the radial direction of the arc-shaped side, of an opening in the plurality of openings located in the edge region; and/or
a dimension, along the extending direction of the arc-shaped side, of an opening in the plurality of openings located in the middle region is greater than a dimension, along the extending direction of the arc-shaped side, of an opening in the plurality of openings located in the edge region.

6. The flexible display screen according to claim 5 , wherein dimensions, along the radial direction of the arc-shaped side, of openings in the plurality of openings located in the middle region are substantially same; and/or
dimensions, along the radial direction of the arc-shaped side, of openings in the plurality of openings located in the edge region are substantially same.

7. The flexible display screen according to claim 5 , wherein a dimension of the deformation region along the radial direction of the arc-shaped side is L1, and a minimum distance, along the radial direction of the arc-shaped side, between a boundary of the middle region and a boundary of the deformation region that are close to each other is in a range of ¼ L1 to ⅓ L1; and/or
a dimension of the deformation region along the extending direction of the arc-shaped side is L2, and a distance, along the extending direction of the arc-shaped side, between a boundary of the middle region and a boundary of the deformation region that are close to each other is in a range of ⅙ L2 to ⅛ L2.

8. The flexible display screen according to claim 2 , wherein along a direction from a center of the deformation region toward the first bending portion and along a direction from the center of the deformation region toward the second bending portion, distances, each of which is a distance between two adjacent openings in openings in each of at least one row, are increased in sequence; and/or
along a direction from a center of the deformation region toward a side boundary of the deformation region along the radial direction of the arc-shaped side and along a direction from the center of the deformation region toward another side boundary of the deformation region along the radial direction of the arc-shaped side, distances, each of which is a distance between two adjacent openings in openings arranged along the radial direction of the arc-shaped side, are increased in sequence.

9. The flexible display screen according to claim 1 , wherein the plurality of openings have a strip shape, and a length extending direction of the plurality of openings is substantially same as the extending direction of the arc-shaped side; and/or a length extending direction of the plurality of openings is substantially tangent to the extending direction of the arc-shaped side.

10.
