3D display apparatus and system

摘要

Disclosed are a display apparatus and a system including the same. A 3-dimensional (3D) display apparatus includes a display unit; a video signal processor which extracts frame sync signals corresponding to a left-eye image and a right-eye image from a predetermined 3D video signal, and processes the left-eye image and the right-eye image to be alternately displayed on the display unit; and a first communication unit which communicates with an external 3D display apparatus, and transmits a display sync signal based on the extracted frame sync signal to the external 3D display apparatus so that a 3D image displayed in the external 3D display apparatus can be synchronized with order of the left-eye image and the right-eye image displayed on the display unit.
