1. A touch control structure, comprising a plurality of first touch electrodes arranged in a plurality of rows and a plurality of second touch electrodes arranged in a plurality of columns;
wherein the plurality of rows of the plurality of first touch electrodes respectively extend to a first edge of the touch control structure;
a respective row of the plurality of rows comprises a plurality of non-edge first electrode blocks and a first edge electrode block, the first edge electrode block being along the first edge;
the plurality of non-edge first electrode blocks have a same shape;
electrode blocks of the plurality of first touch electrodes and the plurality of second touch electrodes are in a same layer, and respectively comprises a main portion and protrusion portions;
the plurality of column of the plurality of second touch electrodes comprise a plurality of non-edge columns and an edge-adjacent column, the edge-adjacent column being directly adjacent to multiple first edge electrode blocks respectively from the plurality of rows of the plurality of first touch electrodes;
the edge-adjacent column comprises a plurality of edge-adjacent electrode blocks electrically connected;
a respective one of the plurality of edge-adjacent electrode blocks comprises a truncated protrusion, and multiple non-truncated protrusions;
an edge of the truncated protrusion is spaced apart from the first edge by a gap;
a gap part of the first edge electrode block is in the gap;
the truncated protrusion extends from a respective main portion of the respective one of the plurality of edge-adjacent electrode blocks along a first direction; and
an area of the truncated protrusion is less than an area of a respective non-truncated protrusion of the multiple non-truncated protrusions.
