Array substrate, touch display panel and display apparatus containing the same, and method for driving the touch display panel

An array substrate, comprising:

• a bottom substrate;
• a plurality of gate lines and a plurality of data lines arranged on the bottom substrate for defining a plurality of subpixel regions;
• and
• a plurality of common electrode pads, each common electrode pad being located in a corresponding subpixel region,
• wherein:
• two or more neighboring ones of the common electrode pads that are in a same row form at least a portion of a self-capacitance electrode,
• the two or more neighboring ones of the common electrode pads in the same row are connected by a common electrode signal line through via holes,
• the common electrode signal line and the plurality of gate lines are formed in a same layer, and
• one of the plurality of gate lines and the common electrode signal line are arranged in a gap between two adjacent rows of the common electrode pads.
