ABSTRACT:
A apparatus and method for driving a liquid crystal display that minimizes the generation of electromagnetic interference (EMI) in a cost effective manner includes a gate control signal generator that generates a gate control signal using a externally inputted synchronizing signal, a data control signal generator that generates a data control signal using the synchronizing signal, a data aligner that re-aligns externally inputted video data, a plurality of buffers at output terminals of the gate control signal generator, the data control signal generator and the data aligner, and a control unit that applies control signals to the buffers to control current values of signals outputted by the buffers.
