TILED DISPLAY DEVICE AND SYNCHRONIZING METHOD THEREOF

摘要

A tiled display device includes a first display device including a first display panel configured to sense a touch thereon and display an image signal, and a first controller configured to control the first display panel and transmit a reference signal wirelessly, and a second display device including a second display panel configured to sense a touch thereon and display the image signal, and a second controller configured to control the second display panel and transmit a first ACK signal to the first controller after receiving the reference signal, in which the first controller is configured to determine a first latency time of the second display device by using the reference signal and the first ACK signal and synchronize touch information of the first and second display devices according to the first latency time.
