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.
