Abstract:
1. A driving method for a liquid crystal display panel, comprising the steps of: applying a couple of scanning signals to a pixel on the liquid crystal display panel, wherein the scanning signals allow voltages to be separately written into a control electrode and a pixel electrode during two adjacent horizontal scanning periods or a vertical scanning period, and a coupled voltage is induced on the control electrode due to a potential variation of the pixel electrode during a next horizontal scanning period or the vertical scanning period, wherein the pixel includes thin film transistors including only a first thin film transistor and a second thin film transistor respectively coupled to the pixel electrode and the control electrode as well as respectively coupled to two adjacent scanning lines, and the first thin film transistor and the second thin film transistor of the same pixel are turned on together during a duration in the vertical scanning period, wherein the scanning signals have the same pulse width, and wherein each of the first and second thin film transistors includes a gate electrode, a first electrode and a second electrode, and the first and second electrodes of the first thin film transistor do not connect to the first and second electrodes of the second thin film transistor, and wherein a potential of the control electrode synchronously changes with a polarity of the pixel electrode such that when a polarity of the pixel is positive the driven potential of the control electrode is higher than a potential of the pixel electrode, and when the polarity of the pixel is negative the driven potential of the control electrode is lower than the potential of the pixel electrode.
