Abstract: A display device includes a timing controller which transmits an image control signal and at a same time receive a feedback signal, a source driver which transmits the feedback signal and receive the image control signal, and a duplex communication path between the timing controller and the source driver, where the timing controller detects a voltage level of a signal received through the duplex communication path and recovers the feedback signal according to the detected voltage level.
