The variation of the electrical properties of the panel component of alternating current plasma display panels with varying power frequencies was investigated and the effects of parasitic factors on the panel were studied. The 42-in. panel exhibited capacitive properties up to 400kHz, showing a self-resonant frequency (f(SR)) at approximately 400kHz, whereas it exhibited inductive properties above 400kHz. As the panel area decreased, the f(SR) of the panel shifted from 400kHz to 650kHz. In addition, as the panel diagonal size increased from 32 to 72 in., the f(SR) decreased from 500kHz to 175kHz. This implies that the panel becomes more sensitive with increasing panel area because the f(SR) approached the typical sustain frequency (approximate to 200kHz). Furthermore, we propose a different energy recovery circuit (ERC) to lower the power consumption in the high-frequency waveform, where the capacitive component in the ERC should be changed to an inductive component when the frequency of the driving waveform is higher than the f(SR).
