A sleep state synchronization method between docked terminals and docking system using the same is disclosed. The state synchronization method between docked terminals includes determining whether or not a first terminal is docked on a second terminal, turning off signal transmitted to a TMDS data line when it is determined that the first terminal is not docked on the second terminal, and the entering by the second terminal into sleep mode. Accordingly, the docked terminals are able to enter into sleep mode together, enabling interlocked operations of the docked terminals instead of operating independently, which would prevent confusion to users when using the docked terminals. In addition, by the aforementioned method, it is unnecessary to make settings for each docked terminal separately, and it is possible to enter into sleep mode easily using TMDS signal of a HDMI interface without going through complex algorithms.
