A driving circuit, a display panel, and a driving method thereof are disclosed. The driving circuit includes a light-emitting module, a data signal writing module, and a control module. The light-emitting module emits light under a driving current. The data signal writing module is connected to the light-emitting module and configured to control a magnitude of the driving current. The control module is electrically connected to the data signal writing module and the light-emitting module. The control module is configured to control a light-emitting time of the light-emitting module under a control of a light-emitting time control signal.
