A study on the driving discharge characteristics of the AC PDP packaged with in-situ vacuum sealing with the MgO layer coated by optimum evaporation rate

AC PDP with MgO protective layer coated with the optimum evaporation rate of 5 Å/s can generate more enhanced efficiency through the vacuum in-line sealing process. However, the optimized process conditions still require the optimum driving scheme on the ramp-up and ramp-down slope of the reset waveform for enhancing discharging efficiency. For the in-situ vacuum sealed PDP with the optimum evaporation rate of MgO protective layer, the delay times of address discharge were investigated with various slopes of ramp waveforms during a reset ramp-up and ramp-down period. And the optimal driving scheme was also obtained.
