    Abstract: The present disclosure provides a driving method and a driver integrated circuit configured to drive a touch screen using such driving method, for shortening a touch time of the touch screen, thereby prolonging a display time of the touch screen and accordingly improving the charging rate of pixels. The touch screen includes a plurality of touch electrodes arranged in an array and is provided with a time period for displaying a frame, which time period is divided into a touch time period and a display time period. The method includes: dividing the plurality of touch electrodes into at least two groups; and during the touch time period of each frame, scanning each group of touch electrodes with a touch scanning duration which the longest one of durations required for scanning the touch electrodes in the group of touch electrodes.

    Abstract: 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.
