A touch screen, a driving method thereof and a display device. Common electrodes (9) of at least part of pixel units (5) on an array substrate (1) form a plurality of touch driving electrodes (3) each comprising at least one common electrode (9); the plurality of touch driving electrodes (3) are grouped into a plurality of touch driving electrode groups (101, 102) each comprising at least one touch driving electrode (3), and a plurality of touch sensing electrodes (4) are formed on a color filter substrate (2), the touch driving electrodes (3) and the touch sensing electrodes (4) are disposed to be intersected horizontally and vertically. Further, a driving circuit (10) is further provided, during a display period in a display time for one frame of picture, a common electrode signal is transferred by the driving circuit (10) to all of the touch driving electrodes (3), while during a touch period in the display time for the one frame of picture, a touch scan signal is only transferred by the driving circuit (10) to the respective touch driving electrodes in one of the touch driving electrode groups (101, 102).
