Abstract
The present invention provides a driving method and a driving device for liquid crystal pixel unit, and a liquid crystal display device. In the driving method, the liquid crystal pixel unit comprises a first pixel electrode, a second pixel electrode and a first shared capacitor; the driving method comprises: providing a charging connection signal for charging the first and second pixel electrodes to an equivalent voltage using the data signal; providing a shared connection signal with an interval of a first time after the charging connection signal is finished, electrically connecting the first shared capacitor with first pixel electrode and changing the voltage on the first pixel electrode; said first time is larger than or equal to 1/10 and smaller than or equal to ¾ of the display period. The driving method is applicable to the liquid crystal display device of VA mode, especially to that of CS-SPVA mode.
