MULTI-VIEW DEVICE, DISPLAY APPARATUS AND CONTROL METHODS THEREOF

摘要

A multi-view device includes a lens unit which operates to selectively transmit or block light; a communication unit which communicates with a display apparatus which is displaying an image; and a controller which receives, from the display apparatus via the communication unit, a beacon signal which synchronizes with a display period of the displayed image, controls an operation of the lens unit based on the beacon signal, and changes, via the communication unit, a reception frequency of the beacon signal based on information relating to a wireless communication environment level between the display apparatus and the multi-view device which is extracted from the beacon signal.
