A self-capacitance touch display panel array substrate and

The present invention discloses a self-capacitance touch display panel and the array substrate, the array substrate comprising: a substrate provided with a gate line, a data line and a common electrode layer, an insulating gate lines and data lines intersecting the substrate defining a plurality of pixel cells arranged in an array; pixel cell comprising: a pixel thin film transistor and the pixel electrode; a common electrode layer comprises a plurality of touch units; further provided on the substrate with a plurality of touch driving thin film transistor; touch unit at least a drain connected to two touch driving thin film transistor, the gate of the two touch driving thin film transistor is connected to different gate lines, two touch driving thin film transistor has a source connected to different data lines. Alignment means touch the multiplexed data lines, so as to provide a common signal unit is a touch or a touch signal, without separately deposited metal layer is made of the touch trace unit, simplifying the production process, reducing the manufacturing cost and the thickness of the panel .
