1. A display panel having a display region, a fan-out region located on a side of the display region, a bonding region located on a side of the fan-out region away from the display region, and a peripheral region surrounding the display region, wherein the peripheral region includes a first sub-peripheral region, a second sub-peripheral region, a third sub-peripheral region and a fourth sub-peripheral region; the first sub-peripheral region and the second sub-peripheral region are respectively located on two opposite sides of the display region in a first direction, the third sub-peripheral region and the fourth sub-peripheral region are respectively located on two opposite sides of the display region in a second direction, and the first direction is substantially perpendicular to the second direction; and the fan-out region and the bonding region are located in the fourth sub-peripheral region;
the display panel comprising:
a plurality of data lines extending from the display region to the fan-out region;
a plurality of data fan-out leads disposed in the fan-out region; wherein each data line is electrically connected to a data fan-out lead; and the plurality of data fan-out leads are gathered to the bonding region;
a gate driving circuit disposed in the display region;
a plurality of control signal lines electrically connected to the gate driving circuit and configured to transmit respective control signals to the gate driving circuit; wherein the plurality of control signal lines extend from the display region to the fan-out region; and
a plurality of first fan-out leads disposed in the fan-out region; wherein each control signal line is electrically connected to a first fan-out lead; and the plurality of first fan-out leads are gathered to the bonding region; wherein
the control signal line includes a first line segment and a second line segment that are electrically connected to each other;
of first line segments of the plurality of control signal lines, some first line segments extend from the third sub-peripheral region, along the first sub-peripheral region, to the fan-out region;
some other first line segments extend from the third sub-peripheral region, along the second sub-peripheral region, to the fan-out region;
second line segments of the plurality of control signal lines extend from the display region to the third sub-peripheral region; and
an end of the first line segment is electrically connected to an end of the second line segment extending to the third sub-peripheral region, and another end of the first line segment is electrically connected to the first fan-out lead.
