Zusammenfassung: | A flat panel display device includes switching elements QA 3 and QA 4 , respectively connected to a voltage Vs and ground to be applied to a panel capacitance Cp when performing light emission relating to image display, for clamping the voltage of the panel capacitance; coils LA 1 and LA 2 each having one end connected to the panel capacitance; a path separation circuit DLA 1 and DLA 2 , connected to the other ends of the coils, for separating paths through which charge/discharge currents flow; a switching element QA 1 connected between the voltage Vs and the path separation circuit; a switching element QA 2 connected between the ground and the path separation circuit; and diodes connected in parallel to the switching elements, in which the resonance reference voltage relating to a power recovery operation is set to a maximum voltage and a minimum voltage to be applied to the panel capacitance, and the paths through which the charge/discharge currents flow are separated to thereby improve the recovery efficiency in a power recovery circuit and enable realization of stable image display operation. |
