The present invention provides a liquid crystal device drive circuit, which includes a gate driver, a source driver, a plurality of gate lines, and a plurality of data lines. The gate lines and data lines define a plurality of pixel units. Each pixel unit includes a thin-film transistor, a common electrode, a pixel electrode electrically connected to the thin-film transistor, a storage capacitor, and a timer switch. The pixel electrode is electrically connected to the thin-film transistor. The common electrode and the pixel electrode constitute a liquid crystal capacitor. The storage capacitor is connected in parallel to the liquid crystal capacitor. The thin-film transistor includes a gate terminal and a source terminal. The gate terminal is electrically connected to the gate line via the timer switch. The thin-film transistor is electrically connected to the gate driver and the source driver respectively by the gate lines and the data lines.
