Abstract
A driving circuit for a liquid crystal display includes a plurality of driving units each including a first OP amplifier, a second OP amplifier and a plurality of switches for switching outputs and feedback paths of the OP amplifiers. Because the switches are disposed in the feedback paths of the OP amplifiers of the driving unit, an output impedance of the driving unit can be effectively reduced and the stable time of the output voltage can be shortened.
