An overdrive method for anti-double edge of LCD uses: a register unit, a signal processing module including a selection unit and a driving-voltage lookup table (ADE LUT) and a plurality of multiplex processing units to effectively save the resources of hardware and to eliminate the double edge phenomenon generated during overdrive liquid-crystal image developing by selecting among present frame driving-voltage values, overdrive voltage values and actually achieved voltage values input from the driving-voltage lookup table and by outputting driving-voltage values suitable for respective situations according to selection signals of a selection unit by the multiplex processing units. The method is added with a complementary table and an operation unit to increase its scope of application, to eliminate double edge generated by different response speeds; and thereby is suitable for various liquid crystal displays.
