Abstract:
1. A source driver output circuit of a thin film transistor (TFT) liquid crystal display (LCD), the source driver output circuit comprising: first through n-th (where n is an integer) voltage generators for receiving first through n-th corresponding input voltages and generating first through n-th sub input voltages; first through n-th switching portions for transferring the first through n-th sub input voltages as first through n-th corresponding output voltages when activated and disconnecting the first through n-th sub input voltages when deactivated; first through n-th sub switching portions for connecting predetermined share lines to the first through n-th output voltages when activated and disconnecting the predetermined share lines when deactivated; and a voltage-generating portion for receiving first and second voltages and for applying the first and second voltages to the share lines.
