The present invention provides an array substrate and a manufacturing method thereof, a touch screen and a display apparatus. The array substrate comprises: a substrate base; and gate lines, data lines and a common electrode layer formed on the substrate base, wherein the gate lines and the data lines define pixel units, and the common electrode layer comprises touch scan electrodes and touch sense electrodes, and wherein common electrode signals are loaded on the touch scan electrodes during a display period and touch scan signals are loaded on the touch scan electrodes during a touch period, and common electrode signals are loaded on the touch sense electrodes during the display period and the touch sense electrodes output touch sense signals during the touch period. In the present invention, as the touch scan electrodes and the touch sense electrodes are formed in the common electrode layer, there is no need to add a new film layer or add new process steps in the manufacturing process, thereby the manufacturing cost is reduced and the production efficiency is improved.
