Abstract: A driving circuit and a synchronization method thereof for a multi-panel display device are provided. The driving circuit includes a first driving chip and a second driving chip which share a power circuit. One of the first driving chip and the second driving chip is set as a master driving chip or a slave driving chip based on a control signal. The master driving chip transmits a power enable signal and a control signal to the power circuit, which triggers the power circuit providing power voltages to the master driving chip and the slave driving chip. When the master driving chip transmits a timing control signal to the slave driving chip, the slave driving chip performs a power synchronization operation to synchronize with the master driving chip based on the timing control signal.
