1. A touch screen, comprising:
a plurality of touch electrode blocks electrically insulated from each other;
a plurality of leads, electrically connected to the plurality of touch electrode blocks, respectively, wherein the plurality of leads and the touch electrode blocks are arranged in the same layer, and the plurality of leads are arranged in a gap between adjacent columns of touch electrode blocks among the plurality of touch electrode blocks,
wherein each of the plurality of touch electrode blocks comprises a main body portion extending along a first direction and a sawtooth portion electrically connected to the main body portion, and the sawtooth portions opposite to each other in adjacent touch electrode blocks are nested with each other,
wherein the main body portion comprises two first edges opposite to each other and two second edges opposite to each other, a length of the first edges is greater than a length of the second edges, both the first edges and the second edges are provided with the sawtooth portion, and the sawtooth portion provided on the first edges is a first sawtooth portion, and the sawtooth portion provided on the second edges is a second sawtooth portion,
wherein the plurality of touch electrode blocks comprise a first touch electrode block and a second touch electrode block that are nested with each other; the second sawtooth portion of the first touch electrode block comprises a plurality of protrusions extending along the first direction, and the first sawtooth portion of the second touch electrode block comprises a plurality of protrusions extending along a second direction, in which one of the plurality of protrusions is disposed on an end of the main body portion of the first touch electrode block, wherein the one of the plurality of protrusions of the second touch electrode block comprises a sub-sawtooth structure having a plurality of sub-protrusions extending along the first direction,
wherein ends of the sub-protrusions of the second touch electrode block are substantially aligned with ends of the plurality of protrusions of the second sawtooth portion of the first touch electrode block in the second direction perpendicular to the first direction.
