摘要： Disclosed are a driving circuit of a plasma display panel (PDP) driving circuit and a driving method thereof, which can simplify the driving circuit and stably secure a sustain discharge waveform. The PDP includes a first electrode applying a ramp-up voltage, a ramp-down voltage, a scan pulse voltage and a sustain discharge voltage; a second electrode applying a ground voltage GND and a level voltage of a second electrode; and a third electrode applying a data voltage for selecting discharge cells in an address period. In the driving method using a driving waveform divided into a reset period, an address period and a sustain period, positive and negative sustain discharge voltages are alternately applied to the first electrode and the ground voltage GND is applied to the second electrode in the sustain period.

摘要： An energy recovery circuit for a plasma display panel (PDP) according to the present invention includes an energy recovery unit recovering and storing energy from the PDP; and a switching stabilizing unit electrically connected to the energy recovery unit to stabilize switching of a sustain discharge pulse applied to the PDP. The switching stabilization unit may include one diode, two switches and one capacitor for energy recovery, or include two switches and an external input voltage source that is an external voltage supply. According to the present invention, the difference of voltages applied to both drain and source terminals of a switch (SW2) for applying a sustain discharge voltage (Vsus) is minimized at the time when the switch (SW2) is switched, so that switching can be stabilized by preventing hard switching from being generated when the sustain discharge voltage is applied to a panel. Further, switching and electro-magnetic interference (EMI) noises of the circuit, generated due to the hard switching can be decreased, and therefore, driving reliability of the circuit can be improved.
