Abstract

Embodiments of the present disclosure are directed to a driving circuit, a driving method, and a display panel. The driving circuit includes a driving transistor, a writing module, a compensation module, a light-emitting control module and a light-emitting device. The driving transistor has a first gate connected to a first node, a second gate connected to a second node, a source connected to a first power supply terminal, and a drain connected to the third node. The writing module is connected to the first node and the third node. The compensation module is connected to the first node, the second node and the third node. The light-emitting control module is connected to the third node and the fourth node. An anode of the light-emitting device is connected to the fourth node, and a cathode of the light-emitting device is connected to the second power supply terminal.
