1. A touch display panel, comprising:

  • a base substrate,a plurality of gate lines provided on the base substrate,a plurality of data lines provided on the base substrate,a common electrode layer formed by a plurality of self-capacitance electrodes arranged in an M*N array;

    a drive integrated circuit; and

    a plurality of touch detection signal lines;

    wherein the plurality of gate lines and the plurality of data lines are insulated from and intersecting with each other to define a plurality of sub-pixels, at least three adjacent sub-pixel columns of the plurality of sub-pixels constitute one pixel column, each sub-pixel column is parallel to an extending direction of the plurality of data lines;

    each of the plurality of touch detection signal lines is located between two adjacent pixel columns, the plurality of touch detection signal lines connects the plurality of self-capacitance electrodes with the drive integrated circuit, at least a part of the two adjacent pixel columns is not provided with the touch detection signal line therebetween;

    in a display stage, the drive integrated circuit provides a common signal to the plurality of touch detection signal lines;

    in a touch stage, the drive integrated circuit provides a touch detection signal to the plurality of touch detection signal lines.
