Patent ID: 7394443

Claim:
A driving apparatus for a liquid crystal display, comprising: a gate control signal generator that generates gate control signals using an externally inputted synchronizing signal; a data control signal generator that generates data control signals using the synchronizing signal; a data aligner that re-aligns externally inputted data; a plurality of buffers provided 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 plurality of buffers to control characteristics of signals outputted by the plurality of buffers, wherein said plurality of buffers includes: a first buffer that receives the gate control signals outputted from the gate control signal generator at a first current value and outputs the received gate control signal at a second current value in accordance with a control signal outputted by the control unit; a second buffer that receives the data control signals outputted from the data control signal generator at a first current value and outputs the received data control signal at a second current value in accordance with a control signal outputted by the control unit; and a third buffer that receives the re-aligned data outputted from the data aligner at a first current value and outputs the received data at a second current value in accordance with a control signal outputted by the control unit.
