ABSTRACT:
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.
