Array substrate, display panel, and display device having a notched display area

1. An array substrate, comprising:

a substrate comprising a display area and a non-display area adjacent to the display area, wherein the non-display area of the substrate away from an end of the display area has a first notch, and a first edge of the first notch disposed near the display area of the substrate is provided with a binding area; and

a chip on film bound to the binding area and passing through the first notch to be bent to a side of the substrate facing away from the display area;

wherein the first notch divides the non-display area of the substrate away from the end of the display area into a first non-display area and a second non-display area; and

wherein a length of the first non-display area along a first direction is same as a length of the second non-display area along the first direction.

2. The array substrate according to claim 1 , further comprising a cell test pad and an Ag glue pad, wherein the cell test pad and the Ag glue pad are both disposed on the first non-display area and/or the second non-display area, and the cell test pad and the Ag glue pad are staggered.

3. The array substrate according to claim 2 , wherein a length of the binding area along a first direction is less than or equal to a length of the first notch along the first direction, and the first direction is perpendicular to a direction in which the non-display area points to the display area.

4. The array substrate according to claim 3 , further comprising a plurality of input pads arranged along the first direction and equally spaced apart from the binding area, wherein a ratio of a length of each of the input pads along the first direction to a length of each of the input pads along a second direction ranges between ⅓ and 100, and the second direction is a direction in which the non-display area points to the display area.

5. The array substrate according to claim 1 , wherein the first direction is perpendicular to a direction in which the non-display area points to the display area.

6. A display panel, comprising:

an array substrate comprising a substrate, wherein the substrate comprises a display area and a non-display area adjacent to the display area, the non-display area of the substrate away from an end of the display area has a first notch, and a first edge of the first notch disposed near the display area of the substrate is provided with a binding area;

wherein the first notch divides the non-display area of the substrate away from the end of the display area into a first non-display area and a second non-display area; and

wherein a length of the first non-display area along a first direction is same as a length of the second non-display area along the first direction, and the first direction is perpendicular to a direction in which the non-display area points to the display area.

7. The display panel according to claim 6 , wherein the array substrate further comprises a cell test pad and an Ag glue pad, the cell test pad and the Ag glue pad are both disposed on the first non-display area and/or the second non-display area, and the cell test pad and the Ag glue pad are staggered.

8. The display panel according to claim 7 , wherein a length of the binding area along a first direction is less than or equal to a length of the first notch along the first direction, and the first direction is perpendicular to a direction in which the non-display area points to the display area.

9. The display panel according to claim 8 , wherein the array substrate further comprises a plurality of input pads arranged along the first direction and equally spaced apart from the binding area, a ratio of a length of each of the input pads along the first direction to a length of each of the input pads along a second direction ranges between ⅓ and 100, and the second direction is a direction in which the non-display area points to the display area.

10. The display panel according to claim 6 , wherein the array substrate further comprises a chip on film bound to the binding area and passing through the first notch to be bent to a side of the substrate facing away from the display area.

11. A display device, comprising:

the display panel according to claim 6 ; and

a backlight module comprising a second notch corresponding to a position of the first notch of the display panel.

12. The display device according to claim 11 , wherein a vertical projection of the display panel on the backlight module is positioned in the backlight module.

13. The display device according to claim 11 , wherein the display panel further comprises a chip on film configured to sequentially pass through the first notch and the second notch to be bent to a side of the backlight module facing away from the display panel.

14. The display device according to claim 13 , wherein a bending apex of the chip on film is positioned within the second notch.

15. The display device according to claim 14 , wherein a ratio of a vertical distance from the bending apex of the chip on film to the first edge along a second direction to a length of the first notch along the second direction ranges between 0.8 and 1.2, and the second direction is a direction in which the non-display area points to the display area.
