1. A display panel, wherein the display panel has a display region and at least two functional component regions, wherein the display region at least partially surrounds the at least two functional component regions, and the at least two functional component regions are arranged along a first direction; and
wherein the display panel comprises:
first signal lines located in the display region, wherein at least part of each first signal line of the first signal lines extends in a first direction, and the first signal lines are arranged in a second direction intersecting with the first direction,
wherein the first signal lines comprise at least one first-type signal line and at least one second-type signal line, wherein one of the at least one first-type signal line at least partially surrounds the at least two functional component regions, and at least one of the at least one second-type signal line is broken at two sides of one functional component region of the at least two functional component regions in the first direction;
wherein the display panel has a dummy line extending in the second direction and comprises a first edge and a second edge that are opposite to each other in the first direction, wherein a distance d1 between the first edge and the dummy line and a distance d2 between the second edge and the dummy line satisfy 0.9≤d1/d2≤1.1, and
wherein the at least two functional component regions comprise a first functional component region and a second functional component region, wherein the dummy line passes through the first functional component region, and one of the at least one second-type signal line is broken at two sides of the first functional component region in the first direction.
