1. A display substrate, comprising:
a base substrate comprising a display area and a non-display area located around the display area;
a blocking dam located in the non-display area and arranged surrounding the display area; and
a plurality of touch-control lines located in the non-display area, wherein at least some of the touch-control lines comprise conductive winding portions to make resistances of the touch-control lines substantially same, an orthographic projection of a conductive winding portion on the base substrate is located between an orthographic projection of the blocking dam on the base substrate and the display area;
wherein the at least some of the touch-control lines comprise a plurality of first touch-control lines and a plurality of second touch-control lines, a conductive winding portion of each of the first touch-control lines is arranged in an independent winding manner, and conductive winding portions of all the second touch-control lines are arranged in a mutually nested winding manner;
wherein the non-display area comprises a first non-display area for bonding with a touch-control chip;
the display substrate further comprises a plurality of first touch-control electrodes located in the display area, each of the first touch-control electrodes extends in a first direction, at least some of the first touch-control electrodes are electrically connected with the first touch-control lines, and the first direction is a direction from the first non-display area to the display area; and
the first touch-control lines are located in the first non-display area, and conductive winding portions of the first touch-control lines are electrically connected with first touch-control electrodes;
wherein a width of a conductive winding portion of a first touch-control line is substantially the same as a width of a first touch-control electrode in a second direction, and the second direction intersects the first direction.
