Abstract
The application provides a display driving circuit, an array substrate, a circuit driving method, and a display device. The array substrate comprises a plurality of rows of scan lines, a plurality of columns of data lines, and a plurality of pixel units being defined by intersecting of the plurality of rows of scan lines and the plurality of columns of data lines; each column of data lines being connected to a reset module; each column of data lines being further connected to a current control module configured to form a first current flowing from a data line connected thereto to a reference voltage line, wherein the pixel unit includes a first transistor and a second transistor, the first transistor and the second transistor have device parameters that are the same or in a predetermined proportion, and a second electrode of the second transistor is connected to the output terminal.
