1. A three-dimensional (3D) display apparatus comprising:
- a power generator which generates power based on a received alternating current (AC) power signal;
a detector which detects zero crossing points of time of the received AC power signal; and
a controller which generates a reference signal based on the detected zero crossing points of time and transmits the reference signal to at least one other 3D display apparatus,wherein the zero crossing points of time of the received AC power signal are points of time at which the AC voltage is 0V at a moment when the AC voltage changes from positive (+) to negative (−
) or from negative (−
) to positive (+), andwherein the controller outputs an image based on the generated reference signal.

Abstract
Apparatus, method, and system for synchronization and a three-dimensional (3D) display apparatus using the same are provided. The 3D display apparatus includes: a power generator which generates power based on a received alternating current (AC) power signal, a detector which detects zero crossing points of time of the received AC power signal, and a controller which generates a reference signal based on the detected zero crossing points of time and transmits the reference signal to at least one other 3D display apparatus.
