When the first feedback signal FRT1 and the second feedback signal FRT2 coincide with each other, the synchronization controller 121 may wait to receive the next feedback signal (S30).

However, if the first feedback signal FRT1 and the second feedback signal FRT2 do not coincide, the synchronization controller 121 may generate a synchronization signal Sync (S120). The synchronization signal Sync may include running time time difference information between the first feedback signal FRT1 and the second feedback signal FRT2.

It has running time information corresponding to the end of the sixth video frame.

Accordingly, the synchronization controller 121 may generate a synchronization signal Sync corresponding to the time difference ΔRT between the first feedback signal FRT1 and the second feedback signal FRT2. The image control module 120 may hold the output of the second image data Data2 by the time difference ΔRT according to the synchronization signal Sync.
