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： The present disclosure relates to display technologies and particularly to a pixel driving circuit and a pixel driving method and a display device. The pixel driving circuit includes a first switching element, a second switching element, a first compensation element, a second compensation element, a driving transistor, a capacitor, and a third switching element. The present disclosure can eliminate the influence of the threshold voltage of the driving transistor on the driving current and ensuring the uniformity of the display brightness of each pixel.
