1. A touch control display panel, comprising:

  • an array substrate and a plurality of pixel units arranged in an array on the array substrate, wherein,the array substrate further comprises a plurality of self capacitance touch control electrodes, the plurality of self capacitance touch control electrodes are arranged in an array, each of the self capacitance touch control electrodes comprises a plurality of electrode blocks, which are corresponding to the plurality of pixel units;

    the array substrate further comprises a plurality of touch control lead wires, which have a one-to-one correspondence relationship with the plurality of self capacitance touch control electrodes, the touch control lead wires are provided in gaps between adjacent columns of pixel units, which are corresponding to the plurality of self capacitance touch control electrodes, and the plurality of self capacitance touch control electrodes are connected with a touch control chip through the corresponding touch control lead wires;

    the plurality of self capacitance touch control electrodes are configured to function as common electrodes in a display period, while function as touch control electrodes in a touch control period;

    the touch control lead wires are configured for transmitting a common electrode signal to the common electrodes in a display period, while transmitting a touch control scanning signal to the self capacitance touch control electrodes in a touch control period, the touch control lead wires are also configured for transmitting a touch control signal to the touch control chip, and the touch control signal is generated by the self capacitance touch control electrodes at a position where the touch control operation occurs;

    wherein, a data line of the array substrate is provided above the touch control lead wires, and the data line and the touch control lead wires are insulated with each other; and

    an orthographic projection of the data lines on the array substrate and an orthographic projection of the touch control lead wires on the array substrate overlap with each other.
