Abstract: A shift register, a driving method thereof and a device are provided. A shift register sub-circuit outputs a gate scanning signal, to dive gate lines. The shift register sub-circuit outputs a touch scanning signal to a touch control circuit, so that the touch control circuit conducts a touch electrode with a touch detection signal terminal in response to the touch scanning signal, and thus, touch driving may be performed. Therefore, the shift register provided by the embodiment of the disclosure is not only capable of realizing scanning driving, but also capable of realizing the touch driving of touch electrodes. In addition, the number of arranged touch detection lines may be reduced, and furthermore, the area of a Fan-out region and the area of a non-display region are reduced.
