In view of this situation, the first connection line 31 in a broken line shape is provided in the embodiment of the present invention, and is connected to the scan line 10 through the second line segment 31b, so as to realize the electrical connection between the scan line 10 and the shift register 20.

In another embodiment, fig. 5 is a partial schematic view of another display panel according to an embodiment of the present invention, fig. 5 only illustrates a corner region of the display panel, and for clarity, the wiring manner of the connection lines 30 is illustrated, and fig. 5 does not illustrate the pixel circuits and the scan lines in the display area AA. As shown in fig. 5, the display area AA has a first edge B1 and a second edge B2 respectively connected to both ends of the arc-shaped corner G; the non-display area NA includes a first non-display area NA1 adjacent to the first edge B1 and a second non-display area NA2 adjacent to the second edge B2; the first non-display area NA1 is located at one side of the display area AA in the first direction x, and at least a part of the shift register 20 is located in the first non-display area NA1; the second non-display area NA2 is positioned at one side of the display area AA in the third direction y. Fig. 5 illustrates that the first edge B1 and the second edge B2 are both straight edges. Wherein at least two first connecting lines 31 are arranged along the third direction y; and the length of the first line segment 31a in the first connecting line 31 gradually decreases in a direction approaching the second non-display area NA 2. This embodiment can realize the echelonment wiring of many first connecting lines 31, can guarantee can not intercrossing between the adjacent first connecting line 31, then can realize setting up first line segment 31a and second line segment 31b and be located the same layer, reduce the rete quantity that first connecting line 31 occupy. The first line segment 31a and the second line segment 31b which extend in different directions can be directly connected in contact without increasing a punching process, so that the manufacturing process of the first connecting line 31 can be simplified. In addition, the plurality of first connecting lines 31 are arranged in a ladder shape, so that the lengths of the plurality of first connecting lines 31 are designed to be gradually transited, and the influence on the display effect caused by sudden change of the load on the corresponding scanning line can be avoided.

In another embodiment, fig. 6 is a partial schematic view of another display panel provided by the embodiment of the invention, as shown in fig. 6, the first connecting lines 31 include first sub-connecting lines 31-1 and second sub-connecting lines 31-2; in the third direction y, the first line segment 31a of the first sub-connection line 31-1 is located at a side of the first line segment 31a of the second sub-connection line 31-2 away from the second non-display area NA 2. The point at which the first line segment 31a and the second line segment 31b are connected is a connection inflection point D of the first connection line 31. As can be seen from fig. 6, in the first direction x, the connection inflection point D of the first sub-connection line 31-1 is located at a distance from the first non-display area NA1 less than the connection inflection point D of the second sub-connection line 31-2 is located at a distance from the first non-display area NA1. That is, the connection inflection point D of the first sub-connection line 31-1 is closer to the first non-display area NA1 than the second sub-connection line 31-2. Since the first and

second segments

31a and 31b of the first connection line 31 extend in different directions, there may be a cross between the second segment 31b of the first sub-connection line 31-1 and the first segment 31a of the second sub-connection line 31-2. In this embodiment, the first line segment 31a and the second line segment 31b may be located at different layers, and the first line segment 31a and the second line segment 31b are connected by a via penetrating through an insulating layer therebetween, so as to ensure that the second line segment 31b of the first sub-connection line 31-1 and the first line segment 31a of the second sub-connection line 31-2 are crossed in an insulating manner. Referring to fig. 2, the second non-display area NA2 can be regarded as a lower frame area of the display panel, the first line segment 31a of the first sub-connecting line 31-1 is located on a side of the first line segment 31a of the second sub-connecting line 31-2 away from the second non-display area NA2, and the shift register 20 connected to the first sub-connecting line 31-1 is further away from the second non-display area NA2, so that the length of the scan line connected to the first sub-connecting line 31-1 is longer. In the embodiment of the present invention, the distance from the connection inflection point D of the first sub-connection line 31-1 to the first non-display area NA1 is smaller than the distance from the connection inflection point D of the second sub-connection line 31-2 to the first non-display area NA1, which is beneficial to increasing the length of the second sub-connection line 31-2, so as to balance the load difference between the scan lines respectively connected to the first sub-connection line 31-1 and the second sub-connection line 31-2, and to ensure uniform display.

In some embodiments, as shown in fig. 6, the plurality of first connecting lines 31 are arranged in the third direction y, and the connection inflection point D of the first connecting line 31 is gradually spaced apart from the first non-display area NA1 in the first direction x in a direction approaching the second display area NA 2. Therefore, the load difference of each scanning line at the position of the lower frame can be balanced.

In another embodiment, fig. 7 is a partial schematic view of another display panel provided by the embodiment of the invention, as shown in fig. 7, a first sub-connecting line 31-1 and a second sub-connecting line 31-2 are adjacent to each other and form a connecting line pair 30Z, and at least two connecting line pairs 30Z are arranged in a third direction y; for the adjacent two pairs of connecting wires 30Z, one is the first pair of connecting wires 3Z1 and the other is the second pair of connecting wires 3Z2, the first sub-connecting wire 31-1 in the first pair of connecting wires 3Z1 is adjacent to the second sub-connecting wire 31-2 in the second pair of connecting wires 3Z 1. In the first direction x, a distance from the inflection point D of the first sub-link 31-1 in the first pair of link lines 3Z1 to the first non-display area NA1 is a first distance, a distance from the inflection point D of the second sub-link 31-2 in the second pair of link lines 3Z2 to the first non-display area NA1 is a second distance, and the first distance is less than the second distance. That is, the plurality of first connecting lines 31 are arranged in the third direction y, and the connection inflection points D of the plurality of first connecting lines 31 are alternately disposed at large and small distances from the first non-display area NA1. The arrangement can ensure that the length difference between the first connecting lines 31 is not large, the load difference on the corresponding scanning lines cannot be overlarge, and the influence on the display effect caused by the sudden change of the load on the corresponding scanning lines can be avoided.

In the embodiment of fig. 7, the first line segment 31a and the second line segment 31b may be disposed at different layers to ensure that the adjacent first connecting lines 31 are insulated from each other when crossing each other.

In some embodiments, as shown in fig. 5, the connection line 30 further comprises a second connection line 32 extending along the first direction x; in the third direction y, the second connection line 32 is located on a side of the first connection line 31 away from the second non-display area NA. In the embodiment of the present invention, the shift registers 20 in the corner non-display area NAG are adapted to the contour shape of the arc-shaped corner G for arrangement, so that there is a misalignment between the shift registers 20 in the corner non-display area NAG and the pixel circuit rows corresponding thereto, the misalignment distance between the shift registers 20 and the pixel circuit rows corresponding thereto is relatively small at the position close to the first non-display area NA1, and the misalignment distance between the shift registers 20 and the pixel circuit rows corresponding thereto is relatively large at the position far from the first non-display area NA1. That is, the misalignment distance between the shift register 20 and the pixel circuit row corresponding thereto is larger as the distance from the first non-display area NA1 is longer. The second connection line 32 led out from the output terminal of the shift register 20 at a position close to the first non-display area NA1 can extend to the display area AA to overlap with the corresponding scan line 10, and the second connection line 32 can be electrically connected to the scan line 10 at the overlapping position through the via hole of the insulating layer without being disposed in a zigzag shape. In the embodiment of the present invention, the line shape of the connection line 30 is designed according to the misalignment between the shift register 20 and the corresponding pixel circuit row, so that the connection line 30 is prevented from being excessively wound in the display area AA, which increases the line length. The influence on the load of the scan line 10 can be reduced, and the connecting line 30 can be prevented from occupying too much space in the display area AA to influence the arrangement of other circuit structures.

In some embodiments, as shown in fig. 5, for adjacent first and second connection lines 31 and 32: the length of the second connection line 32 is smaller than that of the first connection line 31. The second connection line 32 adjacent to the first connection line 31 is the closest one of all the second connection lines 32 to the first connection line 31. The second connection lines 32 are located on a side of the first connection lines 31 away from the second non-display area NA2, and as understood in conjunction with fig. 2, the length of the scan lines connected to the second connection lines 32 is greater than the length of the scan lines connected to the first connection lines 31. The adjacent first connecting line 31 and the second connecting line 32 are junction positions of the two connecting lines, and the length of the second connecting line 32 at the junction position is smaller than that of the first connecting line 31 in the embodiment, so that the complex difference on the scanning lines respectively connected with the first connecting line 31 and the second connecting line 32 at the junction position can be ensured to be small, and the influence on the display effect due to the sudden change of the load on the corresponding scanning lines is avoided.

In some embodiments, as shown in fig. 5, the display panel includes at least two second connection lines 32; the length of the second connection line 32 is gradually decreased in the third direction y and in a direction away from the second non-display area NA 2. In this embodiment, the lengths of the second connecting lines 32 that are continuously arranged are designed to be gradually changed, so that the load difference between the scan lines correspondingly connected to the second connecting lines 32 that are continuously arranged is gradually changed, and the influence of the sudden change of the load on the corresponding scan lines on the display effect is avoided.

In other embodiments, the display panel includes at least two second connection lines 32, and the lengths of the second connection lines 32 are equal, which is not illustrated in the drawings.
