为优化交流等离子体显示器(AC PDP)的单元结构和驱动电压,采用光谱测量系统和交流等离子体显示器宏单元对电极结构参量、带有浮动电极的新型单元结构及维持电压脉冲参量对Ne-Xe混合气体放电辐射的红外光谱的影响进行了实验研究。结果表明,随着维持电极宽度增加,单元放电辐射的828 nm红外光谱的强度提高,而其辐射效率基本保持不变;随着维持电极间隙增大或在维持电极间加有适当宽度的浮动电极,红外辐射光谱的强度及其辐射效率均提高;提高维持电压脉冲频率或幅度,可增加红外辐射强度,但辐射效率降低。
In order to optimize the cell structure and driving voltage of the AC PDP, a spectroscopic measurement system and an AC plasma display panel were used to measure the electrode structure parameters, the new cell structure with floating electrodes and the sustaining voltage pulse parameters. The influence of infrared radiation on mixed gas discharge was studied experimentally. The results show that with the increase of the sustaining electrode width, the intensity of the 828 nm infrared radiation of the cell discharge increases while the radiation efficiency remains basically unchanged. With the increase of the sustaining electrode gap or the floating electrode with appropriate width between the sustaining electrodes, , The intensity of the infrared radiation spectrum and its radiation efficiency are all raised. Increasing the frequency or amplitude of the sustaining voltage pulse can increase the intensity of the infrared radiation but reduce the radiation efficiency.
