Abstract: A timing controller for an LCD panel includes a signal receiver, a data reader, a signal receiver, a logic control unit, and a data conversion unit. The signal receiver receives transmitted signals, and the data reader acquires data from the signal receiver. The logic control unit receives the data acquired by the data reader to generate pixel data, and the data conversion unit receives the pixel data and converts them into serial signals. The timing controller converts the pixel data and the control commands into serial signals, and then they are transmitted in serial to each of the source driver chips.
