Touch display panel, method for manufacturing and driving the same, and display device

A method for manufacturing a touch display panel, wherein the touch display panel comprises an array substrate comprising matrix-arranged touch electrodes and matrix-arranged pixel units, source and drain electrodes, gate electrodes, gate lines, data lines and a touch chip, wherein

• each of the touch electrodes comprises a plurality of common electrodes, one touch lead is arranged between every two adjacent columns of the pixel units, and each of the touch electrodes is connected to a pin of the touch chip via a corresponding touch lead;
• and
• common electrode signals are applied to the touch electrodes via the touch leads in a display phase, touch scanning signals are applied to the touch electrodes via the touch leads in a touch phase, and a touch signal generated at a touch location is transmitted to the touch chip via a touch lead corresponding to the touch location;
• wherein the method comprises
• forming, on a base substrate, a pattern of the matrix-arranged touch electrodes;
• and
• forming, on the base substrate provided with the pattern of the touch electrodes, a pattern of the touch leads between adjacent columns of the pixel units.
