A full-bridge driver circuit comprising four controllable switches (S1, S2, S3, S4) supplies a voltage (Vp) having alternating polarities between a first and a second electrode (E1, E2) of a flat panel display (FP),wherein a series arrangement of a capacitance (Cp) present between the first and a second electrode (E1, E2), an inductor (L1), and a diode (D1) is arranged in parallel with one of the switches (S1), and the diode (D1) is poled to be conductive during a resonance phase (P3) wherein the control circuit (CC) closes one of the switches (S1) so that the inductor (L1) and the capacitance (Cp) form a resonant circuit to reverse the polarity of the voltage (Vp) in an energy-efficient way without requiring any other controllable switches than the ones forming the full-bridge driver circuit.
