在AC-PDP中，随着面板温度的升高，最小驱动电压增加。因此，驱动电压裕度在高温下是不够的。本文研究了高温下驱动电压裕度减小而产生误放电的机理。高温误放电的主要原因是氧化镁表面电子发射能力的增强。我们已经确认，在地址期间，墙上的电荷损失是驾驶期间中最大的。我们证明了高温下的壁电荷损耗不仅与电压差有关，而且与施加电压差的时间有关。因此，壁电荷损失受先前子场中维持放电的数量和地址负载的影响。最后，我们在50英寸高清分辨率面板上采用较窄的扫描时间和较高的扫描电压，改善了高温下的驱动电压裕度。
As the temperature of the panel increases in AC-PDPs, the minimum driving voltage increases. Thus, the driving voltage margin is not sufficient at high temperature. In this paper, we have investigated the mechanism of a misdischarge which is generated due to the decrement of the driving voltage margin at high temperature. The main factor of the high-temperature misdischarge is the increased electron emission ability from the MgO surface. We have confirmed that the wall charge loss in the address period is the largest among the driving periods. We have verified that the wall charge loss at high temperature depends on not only the voltage difference but also the time when the voltage difference is applied. Therefore, the wall charge loss is influenced by the number of sustain discharges in the previous subfield and address load. Finally, we have improved the driving voltage margin at high temperature using a narrow scan time and a high scan voltage in a 50-in panel with HD resolution.
