Electronic device, touch display panel and touch display substrate

A touch display panel, comprising:

• a first substrate, and a second substrate disposed opposite to the first substrate;
• and
• a liquid crystal layer disposed between the first substrate and the second substrate, wherein the first substrate comprises:
• a substrate plate comprising a plurality of TFT transistors;
• a first insulating layer disposed on the plurality of TFT transistors;
• a common electrode layer on the first insulating layer, comprising a matrix of touch display electrodes insulated from each other and arranged in a first and a second directions perpendicular to each other, wherein an opening is disposed in each of the of the touch display electrodes, a total area covered by each of the touch display electrodes and a corresponding opening is identical in shape and dimension, and the openings in the matrix decreases areas sequentially along the first direction;
• a second insulating layer disposed on the first common electrode layer;
• and
• a touch display wire layer comprising a plurality of touch display wires disposed on the second insulating layer above the common electrode layer, along the first direction in parallel, separated from each other in the second direction;
• wherein a single electrode of the matrix of touch display electrodes electrically connects to one wire of the plurality of touch display wires in an one-to-one correspondence through via holes in the second insulating layer;
• and
• wherein each of the touch display electrodes in the first direction overlays more of the plurality of touch display wires due to the decreasing areas of the openings.
