Abstract: A source driver system includes a scan driver and a data driver. The data driver has a signal controller, a data bus, a connector and a plurality of data driver units. The signal controller is connected with the connector with via the data bus to form a first connection relationship such that the data bus is capable of transmitting control signals from the signal controller to the connector. The connector connects with the data driver units via the data bus to form a second connection relationship such that the data bus is capable of transmitting the control signals from the connector to the corresponding data driver units. In a preferred embodiment, the data bus is further arranged to form a third connection relationship among the data driver units such that the data bus is capable of communicating a serial connection signal among the data driver units.
