摘要： An LCD panel driving method and device with charge sharing is disclosed. The LCD panel includes a plurality of switches, a plurality of data lines, a signal driving circuit for generating a plurality of image signals, a charge sharing common voltage driving circuit and a common capacitor having one end connected to the charge sharing common voltage driving circuit through a common voltage node. The method turns the switches on to thereby form the charge sharing common voltage driving circuit and the signal driving circuit as a short circuit, such that charges stored in the common capacitor flow into the data lines to drive the common voltage node to enter in an inverse phase state in order to sequentially turn the switches on and then off to accordingly sample the respective data lines.

摘要： An operational amplifier driver capable of canceling an offset voltage of an operational amplifier includes the operational amplifier, first to third switches and a capacitor. The operational amplifier has a chopper, first and second input terminals and an output terminal. The first switch receives an input voltage and is connected to the first input terminal. The second switch is connected to the first input terminal and the output terminal. The third switch is connected the second input terminal and the output terminal. The capacitor is connected to the second input terminal. Because the operational amplifier driver directly charges/discharges the capacitor through the output terminal, and the polarities of the first input terminal and the second input terminal may be changed, the operational amplifier driver can shorten a charge/discharge time of the capacitor and cancel the offset voltage without increasing a level of an input signal.

摘要： 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.
