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.
