Abstract
The voltage controlled ramp(VCR) waveform has recently been introduced in the reset period prior to addressing for plasma display. However, this method results in the oscillation of the gap voltage when the ramp rate is increased so as to reduce reset period. In this paper a current controlled ramp(CCR) waveform method in the reset period is suggested. This method can suppress the oscillation of gap voltage under the condition of shorter ramp time. Moreover, the reset time can be reduced by about 30 % compared with the VCR method under the same background luminance.
