    Abstract: The embodiments of the present disclosure provide a driving circuit, a driving method thereof and a display apparatus, and relates to the field of display technology. The driving circuit is configured to drive a to-be-driven element and includes a driving element. The driving element and the to-be-driven element are coupled in series between a first operating voltage terminal and a second operating voltage terminal. The driving element comprises a driving sub-circuit, a writing sub-circuit and a gray scale control sub-circuit. The writing sub-circuit writes a first data voltage provided by the first data signal terminal into the driving sub-circuit. The gray scale control sub-circuit transmits the first operating voltage provided by the first operating voltage terminal to the driving sub-circuit. The driving sub-circuit generates a drive current. The gray scale control sub-circuit also controls an on-state duration of the current path.
