摘要： A plasma display device and a driving method according to the present invention erase more wall charges formed on electrodes by controlling a voltage applied to a sustain electrode and a scan electrode during a falling period of a reset period of the next subfield as the number of sustain discharge pulses applied to the scan electrode and the sustain electrode during a sustain period of a previous subfield increases. Different waveforms may be used during the falling period of the reset period for different subfields, to vary a number of wall charges that may be erased.

摘要： An apparatus and method for driving a plasma display panel. In an idle period, a lowest voltage is applied to each circuit of a driving board of a plasma display panel so that a bootstrap capacitor of a switch driving circuit may enter a chargeable state. Therefore, it is possible not only to make the capacity of the bootstrap capacitor of each circuit small, but also to effectively prevent an abnormal discharge or an abnormal operation of each circuit when an abnormal image is inputted.

摘要： A PDP having a driving circuit that reduces the reset voltage of the PDP driving waveforms to make it possible to use low-voltage elements and to achieve high contrasts is disclosed. Since conventional PDP waveforms require very high reset voltages, it causes a problem of intense background light emissions, low contrasts, use of high-voltage components, and increased circuit costs. According to the driving waveforms of the present invention, relative voltage differences between the address electrode and the X electrode and between the X electrode and the Y electrode are considered to design waveforms of low reset voltages, thereby providing high contrasts and low-cost circuit.
