Abstract: Disclosed are a multi-screen display system and a method of correcting a time synchronization of image signals respectively played by unit display panels. The multi-screen display system includes a multi-screen display apparatus configured to include a plurality of unit display panels and a timing sensing apparatus configured to sense, outside the multi-screen display apparatus, time synchronization information about the unit image frames respectively played by the unit display panels. The timing sensing apparatus calculates a time synchronization error between the unit image frames respectively played by the unit display panels, based on the time synchronization information, and transmits the time synchronization error to the multi-screen display apparatus.
