1. A method for driving thin-film electroluminescent displays comprising:

  • generating an alternating signal and providing an output thereof;

    coupling said alternating signal output to an inductance-capacitance resonant tank circuit to produce and maintain a resonant sinusoidal output;

    coupling said resonant sinusoidal output to the backplane electrode of a thin-film electroluminescent display having a backplane electrode and a plurality of segment electrodes by coupling said electroluminescent display in electrical parallel with the capacitance of said resonant tank circuit; and

    controlling each of said plurality of segments to selectively produce a luminous display.
