Abstract
A first transistor comprises a gate coupled to a first scan line, a source coupled to a data line, and a drain coupled to the first storage capacitor. The second transistor comprises a gate coupled to a second scan line, a source coupled to the first storage capacitor, and a drain coupled to the second storage capacitor. A first polarity voltage applied on the data line is stored into the first storage capacitor during a first time period which the first transistor is turned on. The first storage capacitor discharges due to a connection between the first capacitor and the second capacitor during a second time period which the second transistor is turned on. By using such driving method, the difference in voltage between the liquid crystal capacitor and a common voltage is reduced from charge sharing for improving a color washout effect of the LCD panel.
