1. A display panel, wherein the display panel comprises a display area, a light emitting unit located in the display area, and a pixel driving circuit for driving the light emitting unit, the pixel driving circuit is connected to a first electrode of the light emitting unit, and the display panel further comprises:
a base substrate;
a first power line, disposed in the display area of the display panel, wherein an orthographic projection of the first power line on the base substrate is extended along a first direction;
a second power line, disposed in the display area of the display panel, wherein an orthographic projection of the second power line on the base substrate is extended along a second direction, the second direction intersects the first direction, and at least a part of the second power line is connected to at least a part of the first power line through a via hole;
the display area comprises at least a fan-out area and a normal display area, and a portion of the second power line in the normal display area is connected to the first power line through the via hole;
a plurality of first power lines comprise a first sub-power line, the first sub-power line comprises a first sub-power line segment disposed in the fan-out area, and the first sub-power line segment in the first sub-power line is disconnected from remaining part of the first sub-power line;
a plurality of second power lines comprise a second sub-power line, the second sub-power line comprises a second sub-power line segment disposed in the fan-out area, the second sub-power line segment in the second sub-power line is disconnected from remaining part of the second sub-power line, and the first sub-power line segment is connected to the second sub-power line segment; and
a common electrode layer disposed at a side of the base substrate, wherein the common electrode layer is used to form a second electrode of the light emitting unit, and the common electrode layer is connected to the first power line and the second power line.
