Abstract
Three dimensional (3D) glasses and a 3D display apparatus are provided. The 3D glasses receive a sync signal from the 3D display apparatus through at least one of an infrared signal and a radio frequency signal.
Claims20
Three-dimensional (3D) glasses comprising:
- an infrared receiving unit which receives an infrared signal from a 3D display apparatus;
- a radio frequency (RF) communication which communicates with the 3D display apparatus via an RF signal;
- and
- a control unit which controls to receive a sync signal from the 3D display apparatus via at least one of the infrared signal and the RF signal.
1 more element
A three-dimensional (3D) display apparatus comprising:
- an infrared transmitting unit which transmits a sync signal to 3D glasses via an infrared signal;
- a radio frequency (RF) communication unit which communicates with the 3D glasses by using an RF signal;
- and
- a control unit which controls to transmit the sync signal to the 3D glasses through at least one of the infrared transmitting unit and the RF communication unit.
1 more element
A method of synchronizing three-dimensional (3D) glasses and a 3D display device, the method comprising:
- the 3D glasses receiving an infrared signal and a radio frequency (RF) signal from the 3D display apparatus;
- the 3D glasses selecting a sync signal from one of the infrared signal and the RF signal;
- the 3D glasses controlling a left eye glass and a right eye glass according to the selected sync signal.
