New reset waveform with dual-slope falling ramp for full high-definition AC-PDP

The new reset waveform with dual-slope falling ramp is proposed to reduce a reset-period without deteriorating the address discharge characteristics for the full HD AC-PDPs. The proposed reset waveform has two different voltage slopes during a falling reset-period. The first ramp falling voltage slope higher than the conventional ramp falling voltage slope causes a decrease of the wall charges accumulating on the X-Y electrodes, whereas the second ramp falling voltage slope lower than the conventional ramp falling voltage slope causes a decrease of the wall charges between the address electrode. The higher X-bias voltage is additionally applied to the X-electrode so as to adjust the reset discharge during a part of the first voltage-slope period. As a result, the proposed dual-slope reset waveform can reduce the. falling reset period by 50%, compared to the conventional falling reset-period.
