Display substrate having touch function, method for driving the same and display apparatus

A display substrate having a touch function, comprising a plurality of touch driving electrodes extending in a direction parallel to gate lines, wherein

• the touch driving electrodes are divided into N portions, each portion of the touch driving electrodes is arranged in a direction perpendicular to the gate lines, and each portion of the touch driving electrodes is connected to a driving line, wherein N is a positive integer greater than or equal to 2;
• and
• pixels corresponding to an nth portion of the touch driving electrodes are capable of being reset to have a same grey scale value before a touch driving for the nth portion is started, so that liquid crystal molecules corresponding to the nth portion have a same deflection state, wherein
• n is a positive integer greater than or equal to 1 and less than or equal to N;
• during a touch driving time period for the nth portion, the nth portion of the touch driving electrodes is applied with a touch driving signal;
• and
• during a display scanning time period for the nth portion, the nth portion of the touch driving electrodes is applied with a common electrode signal, the nth portion is a 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 the 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.
