1. A touch panel, comprising:
a first touch electrode comprising:
a plurality of first touch electrode blocks sequentially arranged in a first direction and electrically connected;
wherein the first touch electrode block comprises:
a first main body, wherein an outline of the first main body is substantially a quadrilateral, sides of the quadrilateral are sides of the first main body, and top corners of the quadrilateral are corner regions of the first main body,
first side protrusions located on a side of the first main body and extending out in a direction perpendicular to the side, and
a first corner protrusion located in a corner region of the first main body and extending out in a direction perpendicular to a side where the first corner protrusion is located;
wherein two adjacent first touch electrode blocks arranged in the first direction are electrically connected through the first corner protrusions;
the first side protrusions comprise:
an adjacent-type first side protrusion, adjacent to the first corner protrusion and located on a side different from the side where the first corner protrusion is located;
the first side protrusion comprises:
a first side sub-protrusion and a second side sub-protrusion sequentially stacked in the direction perpendicular to and away from the side where the first side protrusion is located; and
the first corner protrusion comprises:
a first corner sub-protrusion and a second corner sub-protrusion sequentially stacked in the direction perpendicular to and away from the side where the first corner protrusion is located; and
a second touch electrode comprising:
a plurality of second touch electrode blocks sequentially arranged in a second direction and electrically connected, wherein the first direction intersects with the second direction;
wherein the second touch electrode and the first touch electrode are crosswise arranged and insulated, the first touch electrode blocks and the second touch electrode blocks are arranged alternatively in a third direction, and the third direction intersects with both the first direction and the second direction;
the second touch electrode block comprises:
a second main body, wherein an outline of the second main body is substantially a quadrilateral, sides of the quadrilateral are sides of the second main body, and top corners of the quadrilateral are corner regions of the second main body,
second side protrusions located on a side of the second main body and extending out in a direction perpendicular to the side, and
a second corner protrusion located in a corner region of the second main body and extending out in a direction perpendicular to a side where the second corner protrusion is located;
wherein two adjacent second touch electrode blocks arranged in the second direction are electrically connected through the second corner protrusions;
the second side protrusions comprise:
an adjacent-type second side protrusion, adjacent to the second corner protrusion and located on a side different from the side where the second corner protrusion is located;
the second side protrusion comprises:
a third side sub-protrusion and a fourth side sub-protrusion sequentially stacked in the direction perpendicular to and away from the side where the second side protrusion is located; and
the second corner protrusion comprises:
a third corner sub-protrusion and a fourth corner sub-protrusion sequentially stacked in the direction perpendicular to and away from the side where the second corner protrusion is located;
wherein an area of at least one of the second corner sub-protrusion and the second side sub-protrusion of the adjacent-type first side protrusion is smaller than an area of the second side sub-protrusion of other first side protrusion; and/or,
an area of at least one of the fourth corner sub-protrusion and the fourth side sub-protrusion of the adjacent-type second side protrusion is smaller than an area of the fourth side sub-protrusion of other second side protrusion.
