Abstract
A method for providing the sustaining waveform to a selected discharge cell of a plasma display panel (PDP) is provided. First, a first pulse of a first voltage falls to a reference voltage is applied between sustain electrodes X and Y. Second, the voltage between electrodes X and Y remains at the reference voltage for a first period. Finally, a second pulse of a second voltage remains at the second voltage for a second period, and falls to the reference voltage is applied between sustain electrodes X and Y. The apparatus for providing the sustaining waveform to a selected discharge cell of a plasma display panel (PDP) includes a first energy recovery circuit, a second energy recovery circuit, a first capacitor and a first bi-directional switch, and a second capacitor and a second bi-directional switch. The first energy recovery circuit, which includes a first inductor and four switches, is connected to the first sustain electrode. The second energy recovery circuit, which includes a second inductor and four switches, is connected to the second sustain electrode. Moreover, the first capacitor and the first bi-directional switch are connected in series between the first sustain elec…
