1. A display substrate having a display area and a peripheral area surrounding the display area, and having a touch function, the display substrate comprising:
a first common voltage line provided in the peripheral area and at least partially surrounding the display area;
a second common voltage line provided in the peripheral area, the second common voltage line being located on a side of the first common voltage line away from the display area and at least partially surrounding the display area; and
an integrated circuit provided in the peripheral area, the integrated circuit being located at a first side of the display area and configured to provide first signals identical to display signals to the first common voltage line and the second common voltage line during a display stage, and provide second signals identical to touch signals to the first common voltage line and the second common voltage line,
wherein the first signals are different from the second signals.
