Apparatus and system for viewing 3d image

A 3D image viewing system, comprising:

• a display apparatus that generates a left-eye image and a right-eye image, alternately displays the generated left-eye image and right-eye image at a predetermined time interval, and outputs 3D image synchronization signals for the displayed left-eye image and right-eye image;
• and
• a 3D image viewing apparatus that receives the synchronization signal from the display apparatus and opens or intercepts a left-eye glass and a right-eye glass in accordance with the synchronization signal,
• wherein the 3D image viewing apparatus includes,
• a synchronization signal receiver that receives the synchronization signal;
• a 3D control signal generator that generates a left-eye glass control signal and a right-eye glass control signal in accordance with the synchronization signal received by the synchronization signal receiver;
• a left-eye glass that opens or intercepts light transmitted to the left-eye glass in accordance with the left-eye glass control signal;
• a right-eye glass that opens or intercepts light transmitted to the right-eye glass in accordance with the right-eye glass control signal;
• a central processor that controls an operation of the 3D control signal generator in accordance with the synchronization signal received by the synchronization signal receiver and transmits the synchronization signal to the 3D control signal generator;
• and
• a power controller that connects or intercepts power supplied to the synchronization signal receiver and the central processor.
