摘要： The present disclosure discloses a shift register unit and a threshold voltage compensation method thereof, a driving circuit and a display apparatus. The shift register unit includes a cascaded output circuit coupled to a pull-up node, a clock signal input terminal, and a cascaded signal output terminal. The shift register unit is configured to transmit a clock signal from the clock signal input terminal to the cascaded signal output terminal under control of the pull-up node. A compensation circuit has a voltage output terminal coupled to the pull-up node, and is configured to provide an output voltage signal through the voltage output terminal during a blanking phase of a frame. The output voltage signal drives reverse drift of a threshold voltage of the cascaded output circuit.

摘要： 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.
