PURPOSE: A converter box is provided to receive an IR signal which is transmitted from a three-dimensional display device and to transmit an RF signal to a liquid crystal shutter glass. CONSTITUTION: An IR(Infrared Ray) receiving unit(10) of a converter box(50) receives an IR signal from a three-dimensional display device(200). A noise cancelling unit(20) of the converter box removes interference of the signal. A signal converting unit(30) of the converter box converts the IR signal into an RF signal. A signal transmitting unit(40) of the converter box transmits the RF signal to liquid crystal shutter glasses. |
