摘要： Disclosed herein are a 3D TV and a system using RF wireless communication and a method for synchronizing a 3D TV system using the same. In the 3D TV system using the RF wireless communication according to an exemplary embodiment of the present invention, two or more 3D TVs transmit and receive synchronous signals through the RF wireless communication, thereby locking the screen synchronization and synchronous signals of the 3D TVs. Thereafter, when the 3D TVs transmits the synchronous signals to the 3D spectacles, the synchronous signals including the time offset are transmitted, having different time difference. As a result, the 3D spectacles can be synchronized with images displayed on the 3D TVs by using time offset information.
