1. An array substrate, comprising:
a base substrate;
a plurality of first signal lines provided on the base substrate;
a plurality of second signal lines provided on the base substrate, wherein orthographic projections of the plurality of second signal lines on the base substrate intersect with orthographic projections of the plurality of first signal lines on the base substrate;
a plurality of touch sensing blocks provided on the base substrate and spaced apart from each other, wherein each of the plurality of touch sensing blocks comprises a plurality of touch electrodes electrically connected with each other and spaced apart from each other; and
a plurality of touch signal lines provided on the base substrate, wherein at least some of the plurality of touch signal lines are electrically connected with the plurality of touch sensing blocks respectively, wherein
the plurality of touch signal lines extend along an extension direction of the plurality of second signal lines, the plurality of touch signal lines are grouped into a plurality of touch signal line groups, each touch signal line group comprises the touch signal lines adjacent to each other, orthographic projections of the touch signal lines adjacent to each other comprised in a same touch signal line group on the base substrate are respectively provided on two sides of an orthographic projection of a same second signal line on the base substrate, each of the orthographic projections of the touch signal lines adjacent to each other and the orthographic projection of the same second signal line comprises a portion provided between orthographic projections of the touch electrodes adjacent to each other on the base substrate, and a layer in which the touch signal lines adjacent to each other are provided is different from a layer in which the same second signal line is provided;
each of the plurality of touch signal lines comprises a plurality of main portions and a plurality of bent portions, and the plurality of main portions and the plurality of bent portions are alternately provided;
an orthographic projection of each of the plurality of main portions on the base substrate is provided in a region between the orthographic projections of the touch electrodes adjacent to each other on the base substrate.
