Drive circuit and control method thereof, and storage medium

A drive circuit for displaying an image, comprising a plurality of array substrate row driving units which are cascaded, wherein the plurality of array substrate row driving units are controlled by a clock signal and a frame start signal when displaying each of frame images, at least one of the array substrate row driving units comprises a pull-up control module, a first inverting module, a second inverting module, a first pull-down holding module, a second pull-down holding module, a pull-up module and a pull-down module;

• the pull-up control module receives a stage transmission signal and a scan driving signal transmitted by an array substrate row driving unit of a previous stage and is electrically connected to the first inverting module, the first inverting module and the first pull-down holding module are both electrically connected to a first node, the second pull-down holding module and the second inverting module are both electrically connected to a second node, the pull-up module and the pull-down module are both electrically connected to a third node, the pull-down module receives the frame start signal when displaying the each of the frame images, the pull-up module receives the clock signal and outputs a scan driving signal of a current stage and a stage transmission signal of the current stage when displaying the each of the frame images, and the first pull-down holding module and the second pull-down holding module are both electrically connected to an output terminal of the stage transmission signal of the current stage;
• wherein the clock signal has a first level, a second level, and a third level periodically set in timing, a potential of the second level is less than a potential of the first level and greater than a potential of the third level, and the clock signal is at the second level during an image blanking period.
