1. A display substrate, comprising a display region and an opening located in the display region, wherein the opening penetrates through the display substrate, and the display substrate comprises:
a base substrate;
a driving circuit layer, provided on the base substrate and comprising a first signal line at least partially surrounding the opening;
a light-emitting component layer, provided on a side of the driving circuit layer away from the base substrate;
an encapsulation layer, provided on a side of the light-emitting component layer away from the base substrate; and
a touch control layer, provided on a side of the encapsulation layer away from the base substrate and comprising a touch control electrode and a touch control compensation electrode, the touch control compensation electrode being electrically connected to the touch control electrode and at least partially surrounding the opening; and
the first signal line at least partially overlaps with the touch control compensation electrode in a direction perpendicular to a main surface of the base substrate,
the touch control electrode comprises a second touch control electrode extending along a second direction, the second touch control electrode comprises a third sub-touch control electrode, the opening is immediately opened on only one third sub-touch electrode, and an area of the third sub-touch electrode is greater than an area of the opening;
the second touch control electrode further comprises a third sub-touch control electrode first sub-electrode and a third sub-touch control electrode second sub-electrode that are located on opposite sides of the opening in a first direction;
the touch control compensation electrode comprises a first touch control compensation electrode, the first touch control compensation electrode comprises a first sub-compensation electrode and a second sub-compensation electrode both extending along an edge of the opening and located on opposite sides of the opening in a second direction, and the first direction intersects with the second direction; and
both ends of the first sub-compensation electrode and both ends of the second sub-compensation electrode are electrically connected to the third sub-touch control electrode first sub-electrode and the third sub-touch control electrode second sub-electrode respectively.
