摘要： A shift register unit, a gate drive circuit, a display device and a drive method. The shift register unit comprises an input circuit (110), a first node reset circuit (120), an output circuit (130) and a noise reduction touch circuit (140). The input circuit (110) is configured to control the level of a first node (PU) in response to an input signal; the first node reset circuit (120) is configured to reset the first node (PU) in response to a reset signal; the output circuit (130) is configured to output a drive signal to an output end (OUT) under the control of the level of the first node (PU); and the noise reduction touch circuit (140) is configured to reset the first node (PU) in response to a turn-on touch signal. The shift register unit can effectively control the potential of the first node in a touch scanning phase, improving the display quality of a display device comprising the shift register unit.

摘要： A gate drive circuit, a touch display device and a driving method are provided. The gate drive circuit (10) includes a plurality of cascaded shift register units (200) and a voltage stabilization circuit (100). Each of the plurality of cascaded shift register units (200) includes a touch scanning control terminal; and the voltage stabilization circuit (100) is connected to a first shift register unit (201) and at least one second shift register unit (202) after the first shift register unit (201), of the plurality of cascaded shift register units (200), and configured to compensate a level of a first node of the group of second shift register units (202) in response to the touch scanning control signal.
