利用所研制的模拟AC PDP放电特性测量装置,对(CaSr)O,(MgSr)O等不同材料形成的保护膜对AC PDP放电特性的影响进行了研究,确定了新颖膜材料的选择方向,探索了使用高发射性能保护膜材料所必须解决的问题,研究结果表明,用(CaSr)O等混合氧化物制成的保护膜的AC PDP具有比单一氧化物低的工作电压和好的老化特性,但工作电压稳态范围却较窄。研究结果还表明氧化物混合的比例不同,ACPDP的工作电压和稳态范围不同,大约在CaO(或MgO)与SrO的重量比达到1:3时,器件的工作电压最低。 相似文献

In this paper, the operation characteristics of an ac plasma display panel (PDP) with Si-doped MgO protecting layer are investigated. The test panels are fabricated with the protecting layers of conventional MgO and Si-doped MgO, and the operation voltage margin, luminous efficacy, and address discharge time lag are observed. Even though the test panel with Si-doped MgO protecting layer showed lower operation voltages, higher luminous efficacy, and shorter statistical discharge time lag, its addressing discharge characteristics become deteriorated as the scanning time is increased from the end time of the reset period. The photon-induced surface conductivity increased by Si doping into MgO, and surface charges on the Si-doped MgO protecting layer showed faster decay characteristics compared to those on the conventional one. It is believed that the impurity doping into the protecting layer can improve the short-period characteristics of an ac PDP, but the long-term stability of surface charge retention is deteriorated. 相似文献

A protecting layer for the dielectric in AC plasma panels 总被引:1,自引:0,他引:1
《Electron Devices, IEEE Transactions on》1976,23(3):313-318
One of the important problems in the development of ac plasma panels is to produce panels that maintain stable characteristics for a long time. A new idea for using a protecting layer over the dielectric layer which isolates the electrodes from the gas was examined and good results were obtained. Moreover, besides stability, a considerable improvement of operating characteristics was achieved, including low-voltage operation capability. Sputtering of the protecting layer, which is thought to govern the life of plasma panels, occurs even to heat-resisting oxides of large binding energy, but the sputtering rate appears to be so slow that it hardly affects the panel life. Also, the rate of decomposition accompanying sputtering is small. The problem of cracks in the protecting layer, which is the cause of defective life characteristics in such respects as migration of the lead component of the dielectric layer onto the protecting layer and the direct exposure of the dielectric-layer glass to the discharge, was solved by process-technique improvements. This paper describes the merit of using a protecting layer, required performance for this layer, and experimental results, and discusses voltage stability and the results of selection of materials for it. 相似文献
