Provided are a sequence controlled timing controller, a bridge integrated circuit, and a method of driving thereof. The bridge integrated circuit which controls an interface unit, an image converting unit, and a transceiver to transmit image to the timing controller when a loading completed signal is received from the timing controller can be provided. Further, the method of driving the bridge integrated circuit and the timing controller to transmit and receive the loading completed signal so that the bridge integrated circuit converts image data and transmits the converted image data to the timing controller can be provided.
