Touch display substrate and display device

A touch display substrate, comprising:

• a plurality of sub-pixel units, arranged in an array, each of the plurality of sub-pixel units comprising a pixel unit switch;
• data lines, each of the data lines arranged at a gap between two adjacent columns of the plurality of first sub-pixel units,
• signal lines, each of the signal lines arranged at the gap between the two adjacent columns of the plurality of sub-pixel units,
• wherein the data lines comprise a first data line, and the signal line is at the gap, where the first data line is located, extending in a column direction,
• wherein the first data line comprises a convergence line and two branch lines both connected with the convergence line, the convergence line and the two branch lines are located in a same gap and at least one of the two branch lines is connected with the pixel unit switch.

A touch display substrate, comprising:

• a plurality of sub-pixel units, arranged in an array and comprising a plurality of first sub-pixel units in a first row of sub-pixel units and a plurality of second sub-pixel units in a second row of sub-pixel units, each of the plurality of sub-pixel units comprising a pixel unit switch;
• data lines, each of the data lines arranged at a gap between two of the plurality of first sub-pixel units;
• and
• touch signal lines, each of the touch signal lines arranged at the gap between the two of the plurality of first sub-pixel units and has a bend shape,
• wherein the data lines comprise a first data line, the touch signal line comprises a first touch signal line, the first data line and the first touch signal line are in a same gap, the first touch signal line is adjacent to and at a side of the first data line;
• wherein the first data line is connected to a pixel unit switch of the second sub-pixel unit, an orthographic projection of the first touch signal line on a base substrate is between a drain region of the pixel unit switch of the second sub-pixel unit and the first data line;
• wherein each of the plurality of sub-pixel units further comprises:
• a pixel unit electrode on the pixel unit switch, and the drain region is electrically connected with the pixel unit electrode.
