The invention discloses a self-contained touch display panel, an array substrate and a touch device thereof. The array substrate comprises a substrate body, grid electrode lines, data lines and pixel units, each pixel unit comprises pixel electrodes, pixel thin film transistors, multiple touch driving thin film transistors, a common electrode layer and a data line gating circuit, grid electrodes of the touch driving thin film transistors are connected with one grid electrode line while first electrodes of the sames are connected with one data line, the common electrode layer comprises multiple touch display electrodes, each touch display electrode is electrically connected with second electrodes of at least two touch driving thin film transistors connected with different grid electrode lines, the touch driving thin film transistors connected with a same grid electrode line and the pixel thin film transistors are different in break-over voltage, and the data line gating circuit is used for controlling set data lines to provide display data signals for set pixel units in a display time sequence period and to provide touch detection data signals for the set pixel units in a touch time sequence period. Making process is simplified, making cost and thickness of the panel are lowered.
