1. A method for driving a display substrate having a touch function, comprising steps of:

  • dividing touch driving electrodes comprised in the display substrate and parallel to gate lines into N portions, wherein each portion of the touch driving electrodes is arranged in a direction perpendicular to the gate lines, and N is a positive integer greater than or equal to 2; and

    resetting pixels corresponding to an nth portion of the touch driving electrodes before a touch driving for the nth portion is started, so that the pixels have a same grey scale value, whereinn is a positive integer greater than or equal to 1 and less than or equal to N;

    a touch driving time period for the nth portion of the touch driving electrodes that is close to touch sensing electrodes, and merely the pixels corresponding to the nth portion are reset, wherein the touch driving time period for the nth portion of the touch driving electrodes occurs within a time period of a display scanning time period for at least another portion of the touch driving electrodes; and

    the touch driving time period for each portion of the touch driving electrodes occurs prior to the display scan time period for each portion of the touch driving electrodes.
