Abstract: A shift register circuit includes a first input sub-circuit, an output sub-circuit and an output control sub-circuit. The first input sub-circuit transmits a signal received at a second signal input terminal to a pull-up node. The output sub-circuit transmits a signal received at a first clock signal terminal to a shift signal output terminal, and transmits a signal received at an output signal transmission terminal to a first scan signal output terminal. The output control sub-circuit transmits a signal received at a chamfering signal terminal to the first scan signal output terminal in a predetermined time before the first scan signal output terminal stops outputting the signal from the output signal transmission terminal. The chamfering signal terminal transmits a signal with a voltage amplitude within a variation range of a voltage amplitude of a signal of the first scan signal output terminal.
