ABSTRACT:
A source driver output circuit of a thin film transistor (TFT) liquid crystal display (LCD) includes first through n-th voltage generators, first through n-th switching portions, first through n-th sub switching portions, and a voltage-generating portion. The voltage generators receive first through n-th corresponding input voltages and generate first through n-th sub input voltages. The switching portions generate the sub input voltages as first through n-th corresponding output voltages when activated, or cut off the sub input voltages when deactivated. The sub switching portions connect predetermined share lines to the output voltages when activated, or cut off the predetermined share lines when deactivated. The voltage-generating portion receives predetermined first and second voltages and applies predetermined precharge voltages to the share lines. Therefore, the slew rate of a signal input to the panel from the source driver can be improved, and current consumption in the source driver can be reduced.
