Optionally, in the display panel 100 provided in the embodiment of the present application, the plurality of second power lines 42 are shorted to at least one conductive line segment 43 in the first non-display area 121. For example, referring to fig. 5, fig. 5 is a partial enlarged view of a first non-display area 121 in a display panel 100 provided in the present embodiment, because each second power line 42 on the display panel 100 is equipotential, the second power lines 42 can be shorted together, in the embodiment shown in fig. 5, a portion of the second power line 42 in the first non-display area 121 is shorted to form a conductive line segment 43, and a portion of the second power line 42 in the first non-display area 121 is transmitted by the conductive line segment 43, so that when the second power line 42 in the first non-display area 121 is shorted to form a conductive line segment 43, a space occupied by the conductive line segment 43 in the first non-display area 121 is smaller, a space occupied by the second power line 42 in the first non-display area 121 is greatly reduced, thereby further reducing a space occupied by the second power line 42 and the second data line 22 in the first non-display area 121, further, the frame width of the first non-display area 121 is reduced, which is more favorable for implementing a narrow frame design of the display panel 100. It should be noted that fig. 5 only shows a situation that the second power line 42 is shorted to one conductive line segment 43 in the first non-display area 121, in some other embodiments, the second power line 42 may also be shorted to two or more conductive line segments 43 in the first non-display area 121, as long as the number of the conductive line segments 43 is less than the number of the second power lines 42 in the display area 11, which is beneficial to reducing the space occupied by the second power line 42 in the first non-display area 121, and is beneficial to implementing a narrow frame design of the first non-display area 121.
Optionally, fig. 6 is another partial enlarged view of the first non-display area 121 in the display panel 100 provided in the embodiment of the present application, where the display panel 100 further includes a voltage drop compensation structure 50, the voltage drop compensation structure 50 is located in the first non-display area 121 and electrically connected to the conductive line segment 43, and the voltage drop compensation structure 50 and the second data line 22 located in the first non-display area 121 are located in different layers.
Specifically, referring to fig. 6, in the display panel 100 provided in the embodiment of the present application, the voltage drop compensation structure 50 is introduced into the first non-display area 121, and when a portion of the second power line 42 located in the first non-display area 121 is shorted to form one or more conductive line segments 43, compared with a method without shorting, a resistance of a portion of the second power line 42 located in the first non-display area 121 changes, so that an overall voltage drop of the second power line 42 becomes larger, in the present application, after the voltage drop compensation structure 50 electrically connected to the conductive line segments 43 is introduced into the first non-display area 121, a resistance formed by the conductive line segments 43 and the voltage drop compensation structure 50 is closer to a resistance of the second power line 42 located in the first non-display area 121 when the conductive line segments 43 are not shorted, which is beneficial to reducing the voltage drop of the second power line 42, thereby being beneficial to improving the display uniformity of the display panel 100, thereby facilitating to improve the display effect of the display panel 100.

In addition, the voltage drop compensation structure 50 and the conductive line segment 43 may be located on the same layer, for example, as shown in fig. 7, and the two may be electrically connected by direct contact, in this embodiment, the conductive line segment 43 and the voltage drop compensation structure 50 may be formed by using the same material and in the same process; of course, the voltage drop compensation structure 50 may also be located in a different layer from the conductive line segment 43, see fig. 8, and electrically connected thereto through the conductive via 48. The conductive line segment 43, the voltage drop compensation structure 50 and the second data line 22 in the first non-display area 121 are respectively disposed in different film layers, which is also beneficial to further reduce the space occupied by the conductive line segment 43, the voltage drop compensation structure 50 and the second data line 22 in the first non-display area 121 after the voltage drop compensation structure 50 is introduced, thereby also being beneficial to realizing the narrow frame design of the display panel 100.
