1. A touch structure, provided on a side of a display substrate, and comprising: a plurality of first touch electrodes and a plurality of second touch electrodes, wherein
the first touch electrodes are arranged at intervals along a row direction, and one of the first touch electrodes comprises a plurality of first electrode blocks arranged at intervals along a column direction and transfer bridges connecting two adjacent ones of the first electrode blocks;
the second touch electrodes are arranged at intervals along the column direction, and one of the second touch electrodes comprises a plurality of second electrode blocks connected in series along the row direction;
one of the transfer bridges is intersected with one of the second touch electrodes, the first electrode block and the second electrode block are located on a same electrode layer and arranged at intervals, the transfer bridge is located on a side of the electrode layer, and an insulation layer is provided between the transfer bridge and the electrode layer;
the first touch electrode and the second touch electrode are mesh structures formed by a plurality of grid lines, grid lines of the first electrode block and the second electrode block are channel lines, the channel lines forming boundaries of the first electrode block are first boundary channel line, and grid lines of the transfer bridge are transfer lines;
the transfer bridge comprises at least two opening parts and a bridge part connecting the opening parts, the opening part and the first electrode block are connected through a via hole penetrating the insulation layer, and the bridge part is intersected with the second touch electrode;
some of the transfer lines of the opening part are boundary transfer lines, and the boundary transfer lines overlap with some of the first boundary channel lines;
the transfer line and the channel line overlapping with each other extend in a same direction; and
among the boundary transfer line and the first boundary channel line overlapping with each other, one side of the boundary transfer line is located on a side of the first boundary channel line close to the adjacent second electrode block, and the other side of the boundary transfer line is located between both sides of the first boundary channel line.
