Abstract: The present disclosure provides an ADS array substrate, a method for manufacturing the same and a display device. The common electrodes of the ADS array substrate serves as touch electrodes, and each touch electrode is electrically connected to a corresponding signal line. In a touch time period of a time period for displaying one frame of image, it is detected whether a self-capacitance of the touch electrode is changed via a corresponding signal line and then a touch position is determined. Each signal line corresponds to a unique touch electrode, then a detection signal obtained via each signal line corresponds to a unique touch electrode, so even though a plurality of touch electrodes are touched, the corresponding touches positions may be determined exactly.
