1. An array substrate for a self-capacitive touch display panel, comprising:
a common electrode layer comprising a plurality of touch electrodes arranged in an array, each column of the array comprising m touch electrodes, wherein m≧2;
a wire layer comprising a plurality of touch wires;
an insulating layer disposed between the common electrode layer and the wire layer, wherein each touch electrode is electrically connected with a corresponding touch wire through a first interconnection structure; and
a plurality of first electrode blocks disposed in a same layer as the common electrode layer, wherein the plurality of first electrode blocks are separated and insulated from the plurality of touch electrodes wherein the m touch electrodes in the same column correspond to m touch wires, wherein each of the m touch electrodes is electrically connected with one corresponding touch wire through the first interconnection structure, and the m touch electrodes overlaps and is insulated from the rest (m−1) touch wires; and
wherein a plurality of hollow portions are disposed in a portion of the touch electrode where the touch electrode overlaps and be insulated from the rest (m−1) touch wires, and the plurality of first electrode blocks are disposed in the plurality of hollow portions and are electrically connected with the rest (m−1) touch wires through the plurality of second interconnection structures respectively.
