New Reset Waveform for High Speed Address Under High Ambient Temperature in AC PDP

Based on the assumption that the wall voltage variation affecting the address discharge delay is deeply related to the exo-emission of the MgO surface especially under the high ambient temperature, the effects of two parameters such as the interval time between sustain- and reset period and the ramp-up holding time of the reset period on the wall voltage variation during the address-period are examined under the high ambient temperature in the 50-in. ac-PDP with full-HD resolution. As a result, the new reset waveform with optimal ramp-up holding time is proposed for a high speed address under high ambient temperature.
