1. A touch display structure, comprising a light-emitting substrate and a touch structure provided on at least one side of the light-emitting substrate, wherein
the touch structure includes a plurality of first touch channels extending along a first direction, and a plurality of second touch channels extending along a second direction, and the first direction and the second direction cross each other; and the plurality of first touch channels and the plurality of second touch channels are insulated from each other, wherein
at least one first touch channel includes multiple adjacent first sub-touch channels, and a first sub-touch channel includes multiple first touch electrodes arranged along the first direction and electrically connected in sequence; and in a same first touch channel, two adjacent first sub-touch channels are electrically connected; and/or
at least one second touch channel includes multiple adjacent second sub-touch channels, and a second sub-touch channel includes multiple second touch electrodes arranged along the second direction and electrically connected in sequence; and in a same second touch channel, two adjacent second sub-touch channels are electrically connected;
the touch structure includes a plurality of metal lines, the plurality of metal lines cross each other to form a plurality of metal grid squares, and the plurality of metal grid squares form first touch electrodes and second touch electrodes in the touch structure; and
the light-emitting substrate includes a plurality of sub-pixels, and each sub-pixel includes a light-emitting region; and orthographic projections of light-emitting regions of at least two sub-pixels on a reference surface are located within a range of an orthographic projection of a same metal grid square on the reference surface, and the reference surface is a plane where the light-emitting substrate is located;
wherein the light-emitting substrate includes a plurality of pixel units, and each pixel unit includes multiple sub-pixels capable of emitting light of different colors; and
orthographic projections of light-emitting regions of the multiple sub-pixels of the pixel unit on the reference surface are located within a range of an orthographic projection of at least one metal grid square on the reference surface; and of the multiple sub-pixels of the pixel unit, orthographic projections of light-emitting regions of at least two sub-pixels on the reference surface are located within the range of the orthographic projection of the same metal grid square on the reference surface.
