Abstract
The present invention provides an analog buffer and a liquid crystal display apparatus using the same and a driving method thereof capable of reducing power consumption. An analog buffer according to the present invention includes: a comparator including an inverter connected in series to the input line; a feedback switch connected between the input line and the output line; and an output inverter, connected between the comparator and the output line, for pre-charging any one of driving voltages of a first driving voltage and a second driving voltage into the output line for a reset interval, and for cutting-off the first and second driving voltages when the pre-charged voltage is fed back via the feedback switch to the input line so that it is converged to the input voltage for a feedback interval.
