Claim 0:
1. A driving circuit of a light-emitting device, comprising:
a light-emitting device, connected in series to a light-emitting circuit formed by a first power signal and a second power signal;
a driving transistor, wherein a source and a drain of the driving transistor are connected in series to the light-emitting circuit, and the driving transistor is configured to control a current flowing through the light-emitting circuit;
a data signal writing module, receiving a first scan signal and a data signal, and electrically connected to one of the source and the drain of the driving transistor, wherein the data signal writing module is configured to write the data signal to one of the source and the drain of the driving transistor under control of the first scan signal;
a first power signal writing module, receiving a second scan signal and the first power signal, and electrically connected to a gate of the driving transistor, wherein the first power signal writing module is configured to write the first power signal into the gate of the driving transistor under control of the second scan signal;
a second power signal writing module, receiving a third scan signal and the second power signal, and electrically connected to the gate of the driving transistor, wherein the second power signal writing module is configured to write the second power signal into the gate of the driving transistor under control of the third scan signal;
a light-emitting control module, receiving a light-emitting control signal and connected in series to the light-emitting circuit, wherein the light-emitting control module is configured to control the light-emitting circuit to be turned on or to be turned off based on the light-emitting control signal; and
a storage module, electrically connected to the gate of the driving transistor and receiving the second power signal, wherein the storage module is configured to store a potential of the gate of the driving transistor.
