摘要： The present disclosure provides a touch module, a driving method thereof and a display device. The touch module includes a touch electrode layer, a touch region determination unit and a touch position detection unit. The touch electrode layer includes a plurality of touch electrode blocks arranged in an array form and independent of each other, and the plurality of touch electrode blocks is divided into N number of touch regions, where N is an integer greater than 1. The touch region determination unit is configured to determine whether each touch region is being touched, and when there is a touch region which is being touched, transmit a detection control signal to the touch position detection unit. The touch position detection unit is configured to, upon the receipt of the detection control signal, detect a position of a corresponding touch electrode block which is being touched in the touch region which is being touched.
