Zusammenfassung:	Provided is a video display system and a signal synchronization device applied in the same. The video display system comprises a video source, a video projection device and a liquid crystal shading device. The video source supplies a video electrical signal and a first clock electrical signal; the video projection device is in signal connection to the video source, and a video projection photosignal and a second clock electrical signal are generated according to the video electrical signal and the first clock electrical signal; the liquid crystal shading device is arranged on a path of the video projection photosignal and is in signal connection to the video source or the video projection device, and the liquid crystal shading device comprises multiple liquid crystal molecules and controls the shading degree of the liquid crystal molecules according to the phase changes of the first clock electrical signal or the second clock electrical signal.
