  • Patent number: 11410587
    Abstract: Disclosed are a shift register unit and a method for driving the same, a gate drive circuit, and a display device. The pull-down control circuit in the shift register unit is capable of controlling a potential of a second pull-up node under control of the input signal provided by an input signal terminal. The pull-down circuit is capable of performing noise reduction on a first pull-up node and an output terminal under control of the second pull-up node. Since the potential of the second pull-up node is not pulled up due to the bootstrap effect, the threshold voltages of transistors in the pull-down circuit are less shifted, and the service life of the shift register unit is relatively long.
