Abstract
A driving circuit for an electric charge recycling TFT-LCD and a method thereof which are capable of preventing a characteristic deterioration of an LCD and TFT by reducing a power consumption of a dot inversion and column inversion methods. The circuit includes a connector unit, e.g., a recycling unit, having a plurality of transmission gates and/or pass transistors connected between the data driving unit and the LCD panel, that recycles electric charges charged in the data line DL in accordance with an electric charge recycling control signal CR during a blank time.
