Abstract
A liquid display panel driving method to drive a plurality of pixels of a liquid display panel in a frame period comprising a plurality of data input intervals is provided. Each pixel comprises first and second capacitors coupled to a first and second common electrode respectively. The liquid display panel driving method comprises the steps of: keeping the second common electrode at the same voltage level; modifying the voltage of the first common electrode of each pixel along a row of scan line to perform a first pre-charge before the data input interval; turning on the pixels to make each pixel receive the data voltage from the data lines during the data input interval; and turning off the pixels and modifying the voltage of the first common electrode to further set the voltage of each of the pixels to a target level after the data input interval.
