Abstract

The present application discloses a display panel including an array substrate, an encapsulation cover plate, an encapsulation layer, and a reinforcement component. The array substrate includes an active area and a non-active area surrounding the active area; the encapsulation layer is disposed between the array substrate and the encapsulation cover plate, and disposed on the non-active area of the array substrate; the encapsulation layer includes an arc-shaped corner; the reinforcement component is disposed between the array substrate and the encapsulation cover plate and disposed outside of the encapsulation layer away from the active area, and the reinforcement component is disposed at one side of the arc-shaped corner away from the active area.

Claims (29)

1 . A display panel, comprising:

an array substrate, comprising an active area and a non-active area surrounding the active area;

an encapsulation cover plate; an encapsulation layer, disposed between the array substrate and the encapsulation cover plate and disposed on the non-active area of the array substrate, the encapsulation layer comprising an arc-shaped corner; and

a reinforcement component, disposed between the array substrate and the encapsulation cover plate;

wherein an arc-shaped corner area is defined between the array substrate and the encapsulation cover plate, and corresponds to one side of the arc-shaped corner of the encapsulation layer, and the one side of the arc-shaped corner is away from the active area; a circle center of the arc-shaped corner is located at another side of the arc-shaped corner adjacent to the active area;

the array substrate and the encapsulation cover plate each comprise a non-arc-shaped corner in the arc-shaped corner area;

a first distance (d 1 ) between the arc-shaped corner of the encapsulation layer and an edge of the array substrate in the arc-shaped corner area is greater than a second distance (d 2 ) between a straight-edge of the encapsulation layer and an edge of the array substrate adjacent to the straight-edge of the encapsulation layer; and

a gap is formed between the reinforcement component and the arc-shaped corner of the encapsulation layer, and the reinforcement component is a single reinforcement block and located in a central region of the arc-shaped corner area;

a cross section of the reinforcement component is in a saw-toothed shape having a plurality of protruding saw teeth, and a sharp angle formed by two edges of each protruding saw tooth proximate to an edge of the display panel is less than a sharp angle formed by two edges of each protruding saw tooth proximate to the arc-shaped corner of the encapsulation layer.

2 . The display panel according to claim 1 , wherein a material of the encapsulation layer is identical to a material of the reinforcement component.

3 . The display panel according to claim 1 , wherein a height of the reinforcement component is a height between the array substrate and the encapsulation cover plate after encapsulation.

4 . The display panel according to claim 1 , wherein the reinforcement component has an upper surface in contact with the encapsulation cover plate and a lower surface in contact with the array substrate.

5 . The display panel according to claim 1 , wherein multiple arc-shaped corners are provided; wherein one reinforcement component is disposed at one side of each arc-shaped corner; and wherein the side of each arc-shaped corner is away from the active area.

6 . The display panel according to claim 1 , wherein multiple arc-shaped corners are provided; wherein reinforcement components are disposed at sides of symmetrical arc-shaped corners; and wherein the sides of the symmetrical arc-shaped corners are away from the active area.

7 . The display panel according to claim 1 , wherein a side surface of the reinforcement component has a protruding portion; wherein an upper surface of the protruding portion is a part of an upper surface of the reinforcement component; and wherein a lower surface of the protruding portion is a part of a lower surface of the reinforcement component.

8 . A display panel, comprising:

an array substrate, comprising an active area and a non-active area surrounding the active area;

an encapsulation cover plate;

an encapsulation layer, disposed between the array substrate and the encapsulation cover plate and disposed on the non-active area of the array substrate, the encapsulation layer comprising an arc-shaped corner; and

a reinforcement component, disposed between the array substrate and the encapsulation cover plate; wherein an arc-shaped corner area is defined between the array substrate and the encapsulation cover plate, and corresponds to one side of the arc-shaped corner of the encapsulation layer, and the one side of the arc-shaped corner is away from the active area; a circle center of the arc-shaped corner is located at another side of the arc-shaped corner adjacent to the active area;

the array substrate and the encapsulation cover plate each comprise a non-arc-shaped corner in the arc-shaped corner area; a first distance (d 1 ) between the arc-shaped corner of the encapsulation layer and an edge of the array substrate in the arc-shaped corner area is greater than a second distance (d 2 ) between a straight-edge of the encapsulation layer and an edge of the array substrate adjacent to the straight-edge of the encapsulation layer;

a gap is formed between the reinforcement component and the arc-shaped corner of the encapsulation layer, and the reinforcement component is a single reinforcement block and located in a central region of the arc-shaped corner area;

a cross section of the reinforcement component is in a saw-toothed shape having a plurality of saw teeth with the same geometry; and a distribution density of saw teeth proximate to an edge of the display panel is less than a distribution density of saw teeth proximate to the arc-shaped corner of the encapsulation layer.

9 . The display panel according to claim 8 , wherein a material of the encapsulation layer is identical to a material of the reinforcement component.

10 . The display panel according to claim 8 , wherein a height of the reinforcement component is a height between the array substrate and the encapsulation cover plate after encapsulation.

11 . The display panel according to claim 8 , wherein the reinforcement component has an upper surface in contact with the encapsulation cover plate and a lower surface in contact with the array substrate.

12 . The display panel according to claim 8 , wherein multiple arc-shaped corners are provided; wherein one reinforcement component is disposed at one side of each arc-shaped corner; and wherein the side of each arc-shaped corner is away from the active area.

13 . The display panel according to claim 8 , wherein multiple arc-shaped corners are provided; wherein reinforcement components are disposed at sides of symmetrical arc-shaped corners; and wherein the sides of the symmetrical arc-shaped corners are away from the active area.

14 . The display panel according to claim 8 , wherein a side surface of the reinforcement component has a protruding portion; wherein an upper surface of the protruding portion is a part of an upper surface of the reinforcement component; and wherein a lower surface of the protruding portion is a part of a lower surface of the reinforcement component.
