摘要:
研究了荫罩式等离子显示屏(SM-PDP)的驱动电压频率从100 kHz到250 kHz变化情况下,显示单元放电特性的变化.结果表明:随着驱动电压频率的提高,在相同的时间内放电次数增加,使产生的真空紫外辐射能量增加,可以提高显示的亮度,获得更高的对比度和灰度等级,同时壁电荷的积累减小,使单次放电反应变弱、放电效率降低,因而过高的驱动频率,也不能起到改善图像质量的作用; 同时电极上的电流峰值减小,而其随时间的平均值增大,在设计驱动电路时,必须考虑其影响.因此在设计SM-PDP时合理的选择驱动电压的频率,可以使PDP的性能有很大的提高.
Abstract:
The discharge characteristics of shadow mask plasma display panel(SM-PDP)under different frequency of driving voltage from 100 kHz to 250 kHz are investigated. The result indicate that with the increase of the frequency of driving voltage, the number of discharge is added,then the energy of ultraviolet photon becomes larger and the brightness is enhanced, more grey levels and contrast can be realized. Meanwhile the wall charge becomes little, individual discharge gets weaker and the discharge efficiency reduces. The maximum current on the electrodes reduces and the average current increases, this should be taken into account in design of driving circuit of SM-PDP. Therefore, by reasonably choosing the frequency of driving voltage in design of SM-PDP, the PDP can be made with better performance.
