1. A shift register configured to be applied to a display apparatus, the display apparatus including a plurality of rows of sub-pixels; the shift register being configured to be electrically connected to at least one row of sub-pixels; the shift register comprising a first scan unit and a black insertion circuit; wherein
the first scan unit includes a first input circuit and a first output circuit;
the first input circuit is electrically connected to a display input signal terminal and a first pull-up node; the first input circuit is configured to, in response to a display input signal received at the display input signal terminal, transmit the display input signal to the first pull-up node; and
the first output circuit is electrically connected to the first pull-up node, a first clock signal terminal and a first scan signal terminal; the first output circuit is configured to, in a case where the first input circuit transmits the display input signal to the first pull-up node, transmit a first clock signal received at the first clock signal terminal to the first scan signal terminal under control of a voltage of the first pull-up node, so as to drive the at least one row of sub-pixels to display an image; and
the black insertion circuit is electrically connected to a first control signal terminal, a black insertion cascade signal terminal, a second control signal terminal, a black insertion input signal terminal, the first pull-up node and a first voltage signal terminal; the black insertion circuit is configured to transmit a black insertion input signal received at the black insertion input signal terminal to the first pull-up node under control of a first control signal transmitted by the first control signal terminal, a black insertion cascade signal transmitted by the black insertion cascade signal terminal and a second control signal transmitted by the second control signal terminal; wherein
the first output circuit is further configured to, in a case where the black insertion circuit transmits the black insertion input signal to the first pull-up node, transmit the first clock signal to the first scan signal terminal under control of another voltage of the first pull-up node, so as to drive the at least one row of sub-pixels to display a black image.
