BI-DIRECTIONAL FULL-DUPLEX LOCK SYSTEM APPLIED IN DATA TRANSMISSION INTERFACE AND OPERATING METHOD THEREOF

摘要

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.

1. A bi-directional full-duplex lock system, applied in a data transmission interface, the data transmission interface comprising at least one transmitter and at least one receiver, the bi-directional full-duplex lock system comprising:
a detection module, the detection module detecting a transmitter link state of the at least one transmitter and a receiver link state of the at least one receiver respectively; and a control module, coupled to the detection module, the control module controlling the at least one transmitter to transmit a lock signal to the at least one receiver, controlling the at least one receiver to transmit the lock signal to the at least one transmitter, and controlling a receiver of the at least one receiver to transmit the lock signal to another receiver of the at least one receiver; wherein the lock signal relates to the transmitter link state and the receiver link state; when the at least one transmitter transmits the lock signal to the at least one receiver, a phase of the lock signal is reversed during a specific period of time for the at least one receiver to detect whether a frequency of the at least one receiver is correct.
