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 the display panel 100 provided by the embodiment of the application, 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 of fig. 5, the portion of the second power line 42 in the first non-display area 121 is shorted to a conductive line segment 43, and the portion of the second power line 42 in the first non-display area 121 is electrically connected to the conductive line segment 43, so that when the second power line 42 in the first non-display area 121 is shorted to the conductive line segment 43, the space occupied by the conductive line segment 43 in the first non-display area 121 is smaller, so that the space occupied by the second power line 42 in the first non-display area 121 is greatly reduced, thereby being beneficial to further reducing the space occupied by the second power line 42 and the second data line 22 in the first non-display area 121, and further being beneficial to reducing the frame width of the first non-display area 121, and further being beneficial to realizing a narrower frame width design of the display panel 100.

Optionally, fig. 6 is a partial enlarged view of a first non-display area 121 in the display panel 100 according to an embodiment of the application, 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 is 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, when the portion of the second power line 42 located in the first non-display area 121 is shorted to one or more conductive line segments 43, compared with the manner of not shorting, the resistance of the portion of the second power line 42 located in the first non-display area 121 changes, so that the overall voltage drop of the second power line 42 becomes larger, and after the voltage drop compensation structure 50 electrically connected to the conductive line segments 43 is introduced into the first non-display area 121, the resistance formed by the conductive line segments 43 and the voltage drop compensation structure 50 together is closer to the resistance of the second power line 42 located in the first non-display area 121 when the shorting is not performed, thereby being beneficial to reducing the voltage drop of the second power line 42, and thus being beneficial to improving the display uniformity of the display panel 100 and further beneficial to improving the display effect of the display panel 100.
Optionally, referring to fig. 7, fig. 7 is a cross-sectional view of another BB' of the first non-display area 121 in the display panel 100 according to an embodiment of the present application, where the voltage drop compensation structure 50 and the conductive line segment 43 are arranged in the same layer; alternatively, referring to fig. 8, fig. 8 is a cross-sectional view of another BB' of the first non-display area 121 in the display panel 100 according to the embodiment of the application, the voltage drop compensation structure 50 and the conductive line segment 43 are located in different layers, and are electrically connected through the conductive via 48.

In addition, the voltage drop compensation structure 50 and the conductive line segment 43 are located in the same layer, for example, referring to fig. 7, and the conductive line segment 43 can be formed by a direct contact method, in this embodiment, the conductive line segment 43 and the voltage drop compensation structure 50 are made of the same material and in the same process; of course, the voltage drop compensation structure 50 may also be located in a different layer than the conductive line segment 43, and an electrical connection is formed between the two via the conductive via 48, see fig. 8. The structure that the conductive line segment 43, the voltage drop compensation structure 50 and the second data line 22 are respectively disposed in different film layers in the first non-display area 121 is also beneficial to further reducing 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 being beneficial to realizing the narrow frame design of the display panel 100.
