Modified reset waveform to widen driving margin under low address voltage in AC-PDPs

In this paper, a new reset driving waveform is proposed to widen a driving margin under the low address voltage in AC-PDPs, The proposed reset waveform can alter the wall charge distribution between the X-Y electrodes by applying the X-ramp bias(ΔVx) prior to an address-period, thus resulting in lowering the minimum level of the scan pulse(ΔVy) during an address-period without a misfiring discharge in off-cells. As a result of adopting the proposed reset waveform, the address discharge time delay is reduced about by 200 ns at an address voltage of 35 V and the related dynamic driving margin is observed to be wide under a low address voltage condition, and its related phenomenon is examined by the Vt close-curve method.
