1. A touch-control display panel, comprising:
a plurality of first touch-control electrodes, wherein each first touch-control electrode comprises a plurality of first sub-electrode groups sequentially arranged along a first direction, adjacent first sub-electrode groups are connected through a bridge;
a first sub-electrode group comprises a plurality of first sub-electrodes sequentially arranged along a second direction and connected, a first sub-electrode comprises two first pattern blocks, a second pattern block located between the two first pattern blocks, and a first connection portion that connects the second pattern block and a first pattern block, which are arranged along the first direction; and
a plurality of second touch-control electrodes, wherein each second touch-control electrode comprises a plurality of second sub-electrode groups sequentially arranged along the second direction and integrally connected; a second sub-electrode group comprises a plurality of second sub-electrodes sequentially arranged along the second direction and connected, a second sub-electrode comprises: two third pattern blocks, a fourth pattern block located between the two third pattern blocks, and a second connection portion connecting a third pattern block and the fourth pattern block, which are arranged along the first direction; and the second sub-electrode is located within a region surrounded by the first sub-electrode, and has substantially a same pattern as the surrounded region, and the second touch-control electrode and the first touch-control electrode are insulated from each other,
wherein the first pattern block, the second pattern block, the third pattern block, and the fourth pattern block are convex polygons,
wherein the first touch-control electrode and the second touch-control electrode are disposed in a same layer and of a same material,
wherein the touch-control display panel comprises a base substrate, a display layer located between the base substrate and the first touch-control electrode, a metal layer located between the display layer and the first touch-control electrode, and an insulation layer located between the metal layer and the first touch-control electrode; and
the metal layer comprises a bridge portion that electrically connects first sub-electrodes of adjacent first sub-electrode groups through a via penetrating through the insulation layer.
