Abstract
A bi-directional full-duplex lock system applied in a data transmission interface of a liquid crystal display is disclosed. The data transmission interface includes a transmitter and a receiver. The bi-directional full-duplex lock system includes a detection module and a control module. The detection module detects a transmitter link state of transmitter and a receiver link state of receiver respectively. The control module controls transmitter to transmit a lock signal to receiver, controls receiver to transmit the lock signal to transmitter, and controls one receiver to transmit the lock signal to another receiver. The lock signal relates to transmitter link state and receiver link state. When transmitter transmits the lock signal to receiver, a phase of the lock signal will be reversed for the receiver to detect whether its own frequency is correct.
