1. An array substrate, comprising a display area and a peripheral area surrounding the display area, wherein the display area is provided therein with display units and comprises a curved edge, the peripheral area is provided therein with a plurality of shift register units cascaded, and wherein
at positions corresponding to the curved edge of the display area, an extending direction in which a first edge of each shift register unit extends is parallel to an outer tangent line of the curved edge or is consistent with an extending direction in which the curved edge extends, and the first edge is an inner edge of each shift register unit close to the curved edge;
each of the shift register units comprises a cascade line connected with an output terminal and a first control terminal of the shift register unit, and the cascade line is arranged along the first edge of the shift register unit;
each of the shift register units further comprises an input unit, a pull-down unit, a pull-down control unit, an output unit and an output control unit, and wherein
the input unit is configured to write a signal of an input terminal into a pull-down node in response to the signal of the input terminal, write a signal of a first voltage terminal into a pull-up node in response to a signal of a first control terminal, and write a signal of a second voltage terminal into the pull-up node in response to a signal of a second control terminal;
the output control unit is configured to write a signal of a third voltage terminal into the output terminal in response to a signal of a first clock terminal;
the output unit is configured to write a signal of a second clock terminal into the output terminal under control of the output control unit and the pull-up node;
the pull-down control unit is configured to write the signal of the first clock terminal into a pull-down control node in response to the signal of the first clock terminal; and
the pull-down unit is configured to write the signal of the third voltage terminal into the pull-down node under control of the pull-down control node and the pull-up node.
