Abstract
A touch screen, a driving method thereof and a display device. Common electrodes () of at least part of pixel units () on an array substrate () form a plurality of touch driving electrodes () each comprising at least one common electrode (); the plurality of touch driving electrodes () are grouped into a plurality of touch driving electrode groups () each comprising at least one touch driving electrode (), and a plurality of touch sensing electrodes () are formed on a color filter substrate (), the touch driving electrodes () and the touch sensing electrodes () are disposed to be intersected horizontally and vertically. Further, a driving circuit () 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 () to all of the touch driving electrodes (), 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 () to the respective touch driving electrodes in one of the touch driving electrode groups ().
