A touch-control electrode structure, display panel, and an electronic device are provided. The touch-control electrode structure includes first touch-control electrodes and second touch-control electrodes; the first touch-control electrodes are arranged along a first direction, and each first touch-control electrode extends in a second direction; the second touch-control electrodes are arranged along the second direction, and each second touch-control electrode extends in the first direction; the first touch-control electrode includes first touch-control sub-electrodes arranged along the second direction; the first touch-control sub-electrode includes a grid-shaped structure; the grid-shaped structure includes a first grid portion and second grid portions, the first grid portion is configured to transmit a touch-control signal, and the second grid portions are spaced apart from and insulated from the first grid portion; and in each first touch-control sub-electrode, the second grid portions are periodically arranged along an extending direction of an edge of the first touch-control sub-electrode.
