交流等离子体显示器的红外辐射光谱

Infrared Radiation Spectrum of Alternating Current Plasma Display Panels

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。

To optimize cell structure and driving voltage of alternating current plasma display panel （AC PDP）, the effects of electrode structure parameters, new-type cell configuration with floating electrodes, and sustained voltage pulse parameters on infrared-radiation spectrum from Ne-Xe mixture gas discharge were experimentally studied by using a spectrum measuring system and a macroscopic AC plasma display panel cell. The results show that as the sustaining electrode width increases, the 828 nm infrared radiation from a macroscopic cell is enhanced, while its radiation efficiency almost keeps constant. As the sustaining electrode gap increases or a floating electrode with appropriate width is inserted between two sustaining electrodes, both the intensity and efficiency of 828 nm radiation are improved. Increasing the frequency or amplitude of sustained voltage can enhance 828 nm radiation, but its radiation efficiency will drop.
