A liquid crystal display enabling circuitry wherein the backplate electrode of a liquid crystal display is activated by a four-level voltage while the respective segment electrodes thereof are activated by a two-level voltage. This includes at least two input terminals, five output terminals, a voltage dividing resistor network and complementary MOSFET switching means and thereby provides the four-level voltage for the backplate electrode and the four-level voltage for the segment electrodes. In addition, this may be implemented with MOS integrated circuitry technology (and not bipolar integrated circuitry technology).
